I don't usually write reviews, not really my thing, but QUBEX did such incredible work for me, I am happy to highly recommend them. My computer crashed with over 5 years of company data and programs on it, and no backup (lesson learned). Apple tried to recover the data, but couldn't. They recommended a few places, but said that QUBEX had the highest success rate. I immediately took my computer over, and Max was extremely friendly and knowledgeable. Within a very short time, he assessed that everything could be recovered, and I had 100% of it on a hard drive within two days (over Mother's Day weekend no less)!! Max verified everything with me on his own computer before I left, and showed me how to transport the old data onto my new computer. Max kept me updated with progress over the entire process, and worked hours I wouldn't expect anyone to work. This was greatly appreciated, as it allowed me to get my business back on track with barely a blip in operations. I couldn't give a more positive recommendation than Max and QUBEX!

This is the most reliable and friendly place I've ever been to to recover the lost data not to mention their competitive pricing and deep computer knowledge. I went to a lot of places before this one and all of them told me my Solid State Drive was dead and they could try to recover it for unbelievable price...well, Max at Qubex exceeded all of the expectations, he did diagnostics on my SSD telling me what was the issue the day after and he recovered my data the next week. Reviews say everything. So do not hesitate and go straight to Qubex if you have any problem with your computer. I would give infinite amount of stars for this review if I could. Thank you so much for the recovered data.

I had a problem with an overheating GPU in my laptop and I took it to him. He cleaned out the old thermal paste and replaced some newer paste in there, and now my laptop's running much cooler. Got it to him at about 5:00 PM, and I got it back by 6:00 on the same day, all for a very reasonable price. Very fast and efficient service, especially since all the other computer repair sites were saying that I had to wait at least 2 or 3 days before they could even begin service. I would definitely recommend him to anyone who has a problem with their computer.

If I could rate more stars I definitely would! My computer crashed last night, the day before my third quarter of an accelerated grad program at DU. I know some basics about computers and I tried everything, ultimately giving up due to a crashed hard drive. After burying myself in bed and crying over my lost capstone, internship notes, essays, research, scholarship applications, resumes, and work projects, I decided to look up local data recovery places. Thank God I found Qubex!!!! Took my laptop in first thing in the morning- hoping for the best. I was told a FREE diagnostic would take a couple of hours and we could go from there. I found out my hard drive was fried but (I never got his name so we will call him Max cause that's what the other reviews say!) Max said he could retrieved ALL of my files and have my computer up and running- BY THE END OF THE DAY. He was there well after closing, just to help me out before classes start tomorrow!!! What an excellent human being!!!! Hanging out and waiting for your repair is like talking with a buddy. We worked out a price I could afford. Very flexible when it comes to payment. He really does just want to help you out and make customers happy. Data recovery isn't cheap and it's hard work so don't expect a miracle. But expect a fair and reasonable price for him salvaging your livelihood. My laptop is top notch now and I am less stressed going into the new quarter. He even advised me on which kind of hard drive I should use, what the pros and cons were, etc. so I could make an informed decision based on more than just price. I cannot emphasize enough how ABSOLUTELY AMAZING this guy is. He is kind, caring, and will teach you a few things about computers while you wait. Hands down THE BEST customer service experience I have ever had in ANY setting!

Recently my hard drive crashed. The local computer repair shop was unable to fix or even access the hard drive. Max at QUBEX was able to completely recover all of my data and offered one day service as well. He also allowed me to review the data to ensure that I had the particular files I needed before payment. For their professional, prompt and quality service I recommend QUBEX.

Max was great. I had a hard drive with broke arm and scratched disk (total loss of unrecoverable data). In my case nothing could be done to fix this except a time machine with a flux capacitor. Max was very upfront about the cost and percentage chance data retrieval. He acted in good business integrity that allowed me to weight the cost of trying a fix. I chose not to, but in the long run he won my future business with all things digital. This is a company I would gladly support in the future.

These guys are great. This is the first time I had to recover any information off any hard drives and I had three hard drives that needed repairing. I had no idea where to go and had heard that getting hard drives fixed was a pain, not to mention costly. So, I Googled up data recovery places and used Thumbtack to reach out to a few businesses in the area. Max contacted me and was really the only one out of few people who offered such a generous price for their services. Their communication with their customers is fantastic. Both Max and Mike stayed in contact with me and allowed me to think about whether or not to move forward with the repairs without being pushy or anything. Once I agreed to let them fix my hard drives they were quick to fix them and even allowed me to preview all of my files before I agreed to pay them. They recovered all of my information and the process couldn't have been more pleasant. They're good guys and they're good at what they do. should go to Qubex if you want your hard drives fixed. Trust me on that.

Transcend has New High-Capacity USB 3.0 Flash Drives Models
Transcend, a maker of flash memory and SSD drives, announced several new USB flash drives in 128 GB and 256 GB capacities. They include the 256 GB JetFlash 780, the rugged 128 GB JetFlash 810, the classic JetFlash 700/730 and the capless JetFlash 790K/790W.
Along with one of the highest capacities on the market, the JetFlash 780 flash drive supports read speeds of up to 210 MB/s and write speeds of up to 140 MB/s, which should make transferring files blazing fast.
At 256 GB, in terms of storage capacity it's almost like you'd be carrying a whole computer drive with you, but in a much smaller package. Transcend said its 256 GB flash drive can store up to 120,000 images, 64,000 mp3s or 64 hours of Full HD video. There are also JetFlash 780 variants that range from 8 GB up to 128 GB.
The JetFlash 810 is a "rugged" flash drive that is splash, dust and shock resistant. It has a rubber housing that meets U.S. MIL-STD-810G 516.6 standards for drop-tests. The drive is available in five colors for each storage capacity.
The JetFlash 700/730 flash drives come in white and black, with a classic design and a LED indicator that turns on when the drives are in operation. The USB 3.0 drives offer speeds of up to 90 MB/s read and up to 40 MB/s write. The 700/730 flash drives are available in storage options from 4 GB to 128 GB. The JetFlash 790K/790W offers a choice of capless and retractable designs that protect the drives and their contents. They also offer USB 3.0 speeds of 90 MB/s read and 40 MB/s write and can be found in capacities from 8 GB to 128 GB.

Toshiba Demonstrates High-Performance Ethernet HDD And SMR Technology
Toshiba has two new Ethernet-connected HDDs on display at OpenStack Summit 2015 that are designed for object storage environments. One device is a standard HDD with a built-in Ethernet connection that leverages SMR (Shingled Magnetic Recording) technology, marking the introduction of the first SMR HDD from Toshiba. The other offering is an innovative combination of an SSD and an HDD in a 3.5" package that connects via Ethernet and runs an open-source Linux kernel on the drive itself.
Object storage is gaining momentum and is shaping up to be the platform of choice for large scale-out applications, primarily because it circumvents many of RAID's limitations. Object storage will address the majority of bulk storage applications, such as primary storage, unstructured data, information governance, analytical data, and archival and cold storage.
The only problem with key/value stores (object storage) is that it isn’t known for its performance. System-level enhancements (such as caching metadata information in server RAM or pools of SSDs) help to cure the speed ailment. However, the entire premise of an Ethernet-HDD architecture is to reduce the number of servers. In the chart above, we see that the use of Ethernet HDDs removes the need for more servers in this deployment due to the fact that each drive presents itself as a node. This is the key value proposition (pun intended) of the approach because it removes the CPUs; RAM and the associated cost, power and management requirements that come with a server cluster. This equates to big cost savings.
However, reducing the servers also reduces the DRAM that is typically used for metadata caching, and it also diminishes the pools of SSDs in the equation. Toshiba's new SSD/HDD Ethernet hybrid, which is currently only referred to as Key Value Drive P (Performance), merges the SSD and HDD into a 3.5" enclosure that can plug into existing Open Kinetic-compatible drive enclosures.
Adding in the ability to run an open-source Linux kernel on the drives' processor unlocks almost endless possibilities. Details are slight on the design, but it is easy to imagine the embedded Linux kernel controlling the SSD and HDD, which could automate caching of the hot data and/or metadata while also allowing new capabilities, such as in-situ information processing. A cluster of these Linux-enabled drives could be designed to coordinate together to create mini-compute clusters for analytics routines, data scrubs, erasure coding calculations and dispersal (without host interaction or traffic), and so on.
Leveraging an open source Linux kernel is key because it will allow the hyperscalers, who will likely be the first to implement this type of architecture, to program their own unique capabilities into the system.
the refined storage stack and hardware implementation possible with an archival or bulk storage application. This type of implementation would not require high performance, and Toshiba proffers its Key Value Drive C (Capacity) product for this use case. The Capacity variant also leverages the Ethernet connection, but it brings SMR into the picture. SMR incurs performance penalties during random write workloads, but this is of little concern for the target use case. The increased density, which provides lower Watts-per-TB metrics, is a welcome addition to vast data repositories (or lakes).
Toshiba is leveraging the Open Kinetic platform, which was pioneered by Seagate. The wisdom behind this decision is important; it will allow Toshiba to interface directly with Open Kinetic APIs and hardware. The emergence of an industry standard for Ethernet HDDs is also important to the long-term viability of this new class of product. All too often, we witness extremely promising technologies that languish in the lab due to a lack of broad acceptance.
HGST also has Ethernet-HDDs in the works that can run an embedded Linux kernel on the drive, so this can help to create broader adoption of techniques to unlock the vast untapped resources that lie in the idling HDD processors deployed by the millions in the datacenter.
Toshiba's unique take on object storage HDDs, with the infusion of SSDs and SMR technologies, offers it an advantage in certain use cases in comparison to the other vendors. The multi-device key value Ethernet drive technology demo is showcased at booth P1 during OpenStack Summit 2015 held in Vancouver, and Toshiba has additional resources available online.

Asus Laptop came in for data recovery service. Laptop Model is G74SX-DH71 with Dual WD 750GB SATA hard drives in RAID-0 array Hard DRIVES MODEL: WD7500BPKT-80PK4T0. Owner claimed that laptop started giving blue screen errors along with instant random shutdowns. Was getting very hot at the bottom and fans were very noisy, then it just would not turn on anymore. Well, if you take a look at the pictures we have made of this laptop, it certainly needed some fresh air and cleaning inside and outside. Besides clogged air duct, this laptop video card has burnt out due t over heat, as well as both hard drives died. DC jack also just melted...This is gaming computer that needs adequate cooling to work properly, which is not the case for this laptop, that's why it has failed. QUBEX data recovery engineers quickly diagnosed it and upon consultation and approval from client we were able to fully recover data from this failed laptop with RAID-0 stripe array on dual western digital drives. We have also repaired video card and replaced DC jack, so owner can continue to enjoy his ownership.
Should you have data loss situation with your laptop, desktop or server - call QUBEX DATA RECOVERY SPECIALIST, we offer free consultation and free diagnostic as well as competitive prices for data recoveries on all devices.

We have received multiple requests, pointing to the fact that there is missing one of the most important information pieces - prices. So it was decided to write a separate article about this.

While we totally understand your desire to know EXACT price for recovery of your hard disk drive or any other storage media, hardware, here on our FB page, when you are looking around the web trying to find best price for data recovery services and comparing various sites and pages in search for it. We would like you to try to understand a few things that affect final price for our or anyone else's data recovery service.

- Nature of the problem
       - Liquid Damage (physical damage)
       - Accidental drop (physical damage)
       - Power Loss (physical, Logical or Both)
       - Firmware Corruption (Logical, mostly)
       - Power Problems ( Both Physical, Logical damages)
       - Virus attack (Logical)
       - Other
 While various liquids have very good penetration abilities, that varies by viscosity, contents, hazardous level, exposure time etc. It is very easy, for any of them, to get inside of your hard disk drive and damage internal components or drive controller board electronic components, some liquids are not so aggressive as others and do not corrode Controller or electronic boards that fast, while others are extremely corrosive or active and oxidize all naked metal parts inside and outside of the storage.
 Hard drive drops causing severe damages inside of the drive. Depending on height, mechanical nature as well as it matters a lot if drive was actually in the process or reading - writing or heads parked and drive is in sleep or off line mode. 
 POWER LOSSES usually do not cause mechanical or physical damages, but again some hard disk drive models have tendency to get mechanical damages while parking heads to the parking ramp. Most of the drives and laptops especially are equipped with free fall sensors or shock sensors to quickly move head stack to the safe position. Power losses can also cause FIRMWARE CORRUPTION or Service Area (a special area on the drive that holds certain data related to the EXACT drive) While hard disk drive manufacturers trying to duplicate that data to a level of redundancy either on different platters, areas, flash chips etc  it is still possible that this crucial data will get corrupted. 
 Another type of a problem is a VIRUS attack, some viruses infect your files or data and cause it to be useless, some viruses delete certain or all data and some encrypt your data, demanding ransom.  

- Level or Severity of the damage
       - Scratched platters
       - Bent Head suspension
       - Residue, Dust inside of a chamber
       - Defunct motor
       - Burnt Electronic Components on PCB controller board
       - Bent or thorn connectors
       - Other
SCRATCHED PLATTERS is common physical or mechanical problem that our data recovery experts see on daily basis. Usually this happens when heads are touching surface due to an impact or shock caused by improper handling or usage of the drive unit, causing permanent damage. Some platters can even shutter (ceramic or glass platters inside of HITACHI or Seagate models for example) If this happens recovery most likely will be impossible to successfully complete. User actions, after something like this happens, are CRITICALLY IMPORTANT. Most you probably will try to turn your laptop on or connect your drive to an external enclosure trying to see if drive survived... this is very bad and dramatically decreasing chances for successful data recovery, no matter what kind of tools you have or how sophisticated your software is. Many of users start looking for data recovery videos on Youtube in search for quick and easy fix for a data loss situation they are in. Again, this will most likely cause more bad than good. While we wow do-it-yourself techniques on average user level, you should think twice before attempting anything at home. In most cases you will need clean room environment or clean bench to do anything with drives. Good soldering skills and programming skills will benefit but wont guarantee success in data recovery. Big companies spend millions of dollars in R&D (research and development) trying to find out best way to recover data from various hard drive brands and models. Which will be covered in the next section.

- Brand Name and Model of Hard Disk Drive, Media
       - Seagate
       - Western Digital 
       - Toshiba
       - Samsung
       - Hitachi
       - Fujitsu
       - Other
Various Brands keep their know-how in strict secret, patent it and wont any one else even sneak peak on it, outside of the strict level of access for own engineers. While certain open source information is available for all, to avoid legal litigation that may cost millions or even billions of dollars in additional costs. No one wants it. So this information is kept secret. Manufacturers trying to improve or evolve their methods of data storage, data reading and writing techniques all the time, having uber geeks with lots of experience and knowledge to design storage that will meet present time requirements of mass storage, they also need to meet certain computer standards without sacrificing speed, affordability of an end product. What we trying to say is that every brand has their own peculiarities that will affect overall data recovery process or technique with necessity to have certain hardware or software tools and more or less time to alter or fine tune things, which again will count in to the total price of data recovery process.  

- Type of a storage media
       - Server RAID (Multiple physical drives, one more logical)
       - Hard disk drive
       - Solid State Drive 
       - Flash Drive 
       - Optical Disk
       - Tape or Floppy etc.
       - Other
This section is pretty self explanatory. Server RAID arrays are probably most complicated recoveries, thus costing thousands of dollars. Not only it may have multiple hardware problems with drives, but logical or software problems too. Different level of RAID arrays have their own pros and cons, number of minimum required drives and logical structure. Flash drives and Solid state drives dont have any moving parts inside, instead of a spinning platters they use FLASH memory chips to store data. We will not go in to the depths of flash memory chips data recovery or solid state drive principals of functionality, we just say, working with it resembles RAID functionality, thus raising the price for data recovery.
- Parts availability and price
       - New models are hard to find
       - Old models are hard to find
       - Unusual media
       - Other
Many new hard drives, solid state drives, basically any storage device that is new on the market is has not been researched enough by data recovery enthusiasts or data recovery companies and does not have enough failures varieties to have statistical data, that can be used to address data recovery price. Data recovery engineers may need to spend hours or days, researching functionality of the unit before they will find out the way to gain access to user area or user data. Plus newer generations of drives using encryption more and more... There are various so called SELF ENCRYPTING DRIVES with high security systems implemented on hardware or software level. Besides various types of encryption used, the depths of encryption are differ too, 32 bit, 64 bit, 128 bit, 256 bit, 512 bit,1024 bit,  2048 bit or even more. Making it practically impossible to decrypt even on super computers. This requires lots of trial and errors, spent dollars, hours of precious time and more. Older drives  may be hard to recover due to outdated software, interface or absence of parts. Some MFM or RLL drives are extremely costly to recover nowadays. Certain streamer tapes are hard to recover due to simple absence of drive that can read this tape or perhaps tape itself deteriorated or lost magnetic properties.

- Type of Data, Size
       - Picture
       - Video
       - Data Base
       - Virtual Machine file
       - Size of a single file
       - Encryption
       - Operating System or File System
       - Other
Many Picture files or system files have small sizes thus easily recoverable even in case of a physical damages, this is because drives nowadays are writing data in various patterns using certain chunks of data to store in a single physical cell or logical sector. In case of a multiple platters, most modern drives, data is being split between heads, platters, surfaces to achieve fast turnaround and data availability, so in case you have multiple surface damage, reading from those surfaces would be hard or impossible, but other platters can still be read, thus smaller the file size the bigger chance it resides on one side of a platter. In turn big files such as Virtual machine files, virtual disks or databases reside on multiple platters and if certain platter is damaged whole file may be damaged and rendered unusable. Sometimes data recovery in such cases may require multiple donor parts which in turn raises total data recovery price.

- Occupancy of the drive, media (how full it is)
       - 5%
       - 50%
       - 100%
       - Other
Occupancy of the drive matters too, the more data is on the drive, the bigger possibility that required data will be corrupt. Please see above section.

While above mentioned factors are very general, this information should give you a clue why we are not writing our prices - because EACH and EVERY data recovery case is UNIQUE. Price also depends on particular company policies and business models, we strongly advise you to get familiar with all details before submitting the case. Do you own diligent research, check online feedback, reputation and so on. While we DO provide BULK PRICE information during initial conversation we PREFER to have your media evaluated by professional data recovery expert. You will not only increase your chances for recovery, but will avoid lots of aching. Many data recovery companies offer FREE EVALUATION or FREE DIAGNOSTIC of your drive as well as FREE RETURN SHIPPING in case you live far away.

Data loss prevention is very important. Do backups, use cloud services (use cloud wisely ;-) create redundancy.

We see in last months new SSD's are appearing in various form factors and working on different protocols or buses, therefore we decided to shed some light on one of them, which currently gaining popularity along enthusiasts and server users - NVMe aka NVM Express
NVM Express, NVMe, or Non-Volatile Memory Host Controller Interface Specification (NVMHCI), is a specification for accessing solid-state drives (SSDs) attached through the PCI Express (PCIe) bus. "NVM" stands as an acronym for non-volatile memory, which is used in SSDs. As a logical device interface, NVM Express has been designed from the ground up, capitalizing on the low latency and parallelism of PCI Express SSDs, and mirroring the parallelism of contemporary CPUs, platforms and applications. By allowing parallelism levels offered by SSDs to be fully utilized by host's hardware and software, NVM Express brings various performance improvements.
NVM Express SSDs exist both in form of standard-sized PCI Express expansion cards and as 2.5-inch drives that provide a four-lane PCI Express interface through an SFF-8639 connector. SATA Express storage devices and the M.2 specification for internally mounted computer expansion cards also support NVM Express as the logical device interface.
Historically, most SSDs used buses such as SATA, SAS or Fibre Channel for interfacing with the rest of a computer system. Since SSDs became available in mass markets, SATA has become the most typical way for connecting SSDs in personal computers; however, SATA was designed primarily for interfacing with mechanical hard disk drives (HDDs), and has become increasingly inadequate as SSDs have improved. For example, unlike hard disk drives, some SSDs are limited by the maximum throughput of SATA.
High-end SSDs have been made using the PCI Express bus before, but using non-standard specification interfaces. By standardizing the interface of SSDs, operating systems only need one driver to work with all SSDs adhering to the specification. It also means that each SSD manufacturer does not have to use additional resources to design specific interface drivers. This is similar to how USB mass storage devices are built to follow the USB mass-storage device class specification and work with all computers, with no per-device drivers needed.
The first details of a new standard for accessing non-volatile memory emerged at the Intel Developer Forum 2007, when NVMHCI was shown as the host-side protocol of a proposed architectural design that had ONFI on the memory (flash) chips side.A NVMHCI working group led by Intel was formed that year. The NVMHCI 1.0 specification was completed in April 2008 and released on Intel's web site.
Technical work on NVMe began in the second half of 2009.The NVMe specifications were developed by the NVM Express Workgroup, which consists of more than 90 companies; Amber Huffman of Intel was the working group's chair. Version 1.0 of the specification was released on 1 March 2011, while version 1.1 of the specification was released on 11 October 2012. Major features added in version 1.1 are multi-path I/O (with namespace sharing) and arbitrary-length scatter-gather I/O. It is expected that future revisions will significantly enhance namespace management. Because of its feature focus, NVMe 1.1 was initially called "Enterprise NVMHCI". An update for the base NVMe specification, called version 1.0e, was released in January 2013.In June 2011, a Promoter Group led by seven companies was formed.
The first commercially available NVMe chipsets were released by Integrated Device Technology (89HF16P04AG3 and 89HF32P08AG3) in August 2012. The first NVMe drive, Samsung's XS1715 enterprise drive, was announced in July 2013; according to Samsung, this drive supported 3 GB/s read speeds, six times faster than their previous enterprise offerings. The LSI SandForce SF3700 controller family, released in November 2013, also supports NVMe. Sample engineering boards with the PCI Express 2.0 ×4 model of this controller found 1,800 MB/sec read/write sequential speeds and 150K/80K random IOPS.A Kingston HyperX "prosumer" product using this controller was showcased at the Consumer Electronics Show 2014 and promised similar performance. In June 2014, Intel announced their first NVM Express products, the Intel SSD data center family that interfaces with the host through PCI Express bus, which includes the DC P3700 series, the DC P3600 series, and the DC P3500 series. As of November 2014, NVMe drives are commercially available.
In March 2014, the group incorporated to become NVM Express, Inc., which as of November 2014 consists of more than 65 companies from across the industry. NVM Express was formed as an industry association to define a new storage interface protocol, NVM Express, to enable the full performance potential provided by the storage technology based on non-volatile memory. NVM Express specifications are owned and maintained by NVM Express, Inc., which also promotes industry awareness of NVM Express as an industry-wide standard. The NVM Express, Inc. is directed by a thirteen-member board of directors selected by the promoter group, which includes Avago Technologies, Cisco, Dell, EMC, HGST, Intel, Micron, NetApp, Oracle, PMC, Samsung, SanDisk and Seagate
Comparison with AHCI
While Advanced Host Controller Interface (AHCI) interface has the benefit of legacy software compatibility, it does not deliver optimal performance when an SSD is connected via PCI Express bus. This is because AHCI was developed back at the time when the purpose of a host bus adapter (HBA) in a system was to connect the CPU/memory subsystem with a much slower storage subsystem based on rotating magnetic media. Such an interface has some inherent inefficiencies when applied to SSD devices, which behave much more like DRAM than like spinning media.
NVMe has been designed from the ground up, capitalizing on the low latency and parallelism of PCI Express SSDs, and fulfilling the parallelism of contemporary CPUs, platforms and applications. At a high level, the basic advantages of NVMe over AHCI relate to its ability to exploit parallelism in host hardware and software, manifested by differences in depth of command queues, interrupts processing, the number of uncacheable register accesses etc., resulting in various performance improvements.

Samsung To Release Magician 4.6 and 840 EVO Firmware Update — Performance Degradation Fixed At Last?
Some owners of Samsung 840 EVO SSDs were among an unfortunate group that began to experience performance degradation over time. (We previously covered this here and here) In a nutshell, their drives could not read “cold” data (that had sat unmodified for an extended period of time) at full speed. This issue thus far has been mostly limited to 840 EVO SSDs with 19nm TLC NAND (planar, not 3D-VNAND).
The first attempt at fixing the issue was via a combination of a firmware update and a software tool. The software tool initiated a one-time “refresh”, causing all stale data to be rewritten. Although this restored performance back to optimal speeds, many users were skeptical (and rightly so) that their drives would eventually deteriorate back to the same state over time.
Allyn Malventano over at PC Perspective has been involved in this issue from its first appearance, and has worked directly with Samsung in helping identify the underlying problem, and beta-testing the “fixes”. You can read his review of the combination of the latest firmware update, and of Samsung Magician 4.6 here. There is a nice little “Q & A” between Allyn and Samsung about what the firmware update and the new Samsung Magician 4.6 software are able to accomplish.
The initial conclusion is that the firmware update does its own periodic refreshing of data, to eliminate the “stale data” issue altogether. Along with the revised firmware there is an “Advanced Performance Optimization” function that can be triggered within Samsung SSD Magician. For owners who never tried the one-time “Performance Restoration Tool” stop-gap fix, they can skip that completely and update to the new firmware, and hopefully be good to go.
Once users have downloaded the latest Samsung Magician 4.6 software, they will see an “Advanced” tab under “Performance Optimization.” The “standard” optimization merely triggers the TRIM function to execute on all empty portions of the SSD. The “Advanced” performance optimization triggers the same action that was triggered by the previous “Performance Restoration Tool.” The original was for one-time usage; but this version available through Samsung SSD Magician can be triggered whenever, or as frequently as desired.
Allyn’s review demonstrates “before firmware update”, “after firmware update”, and “after firmware update and after advanced optimization” results. These results show that merely updating the firmware enables a large improvement in read speeds of the stale data. This may indicate that the read algorithm has been tweaked to compensate for “cell drift over time”. Running the advanced optimization function refreshes the data (likely in a sequential pattern), showing that randomly written files are restored to an even better state than they were previously.
t took Samsung a little while, but it appears that they have finally resolved the 840 EVO performance degradation issue. In the process, Samsung has given the 840 EVO an added feature via the “Advanced Performance Optimization” tool. As Allyn puts it, “….so in trying to fix one problem, they have actually added a useful feature to this product line.” It will be interesting to see if this feature is made available for any other Samsung SSDs, particularly the “non-840 EVO” other SSDs that utilize TLC NAND.

HGST Announces VMware VSAN Support And Increases 12 Gb/s SAS SSD MTBF
HGST, a Western Digital Company, announced that a broad swath of its products have been certified for VMware Virtual SAN (VSAN). The move to software-defined storage architectures is fueling a broad rethinking of the status quo for datacenter architectures, and VSAN is one of the industry's key approaches to migrating away from centralized SAN storage appliances.
HGST has certified a range of its hard drives and SSDs to work with VSAN, giving users the option to leverage multiple interoperable storage tiers with HGST products in VSAN environments. VMware added a spate of HGST devices to the VMware Compatibility Guide, including the Ultrastar He6 SAS 512n, the C10K1800 SAS 512n and the C15K600 SAS 512n HDDs. We recently posted a competitive performance analysis of the 4Kn C15K600 in the HGST Ultrastar C15K600 15K Enterprise HDD review.
4Kn HDDs aren't included on the VSAN compatibility list, but this is due to VMware's lethargic response to 4Kn compatibility in general. 4Kn format HDDs are poised for broader penetration into the enterprise at large, but until VMware pulls the trigger, the company will remain one of the primary inhibitors to 4Kn's broader adoption. VMware has signaled that it will support 4Kn in the future, but it has not provided a meaningful timeline.
HGST's VSAN-certified SSD products include the entire HGST FlashMAX PCIe SSD family, the s1122 PCIe Accelerator, the S842 and S846 SAS SSDs, and the entire family of 12 Gb/s SAS Ultrastar SSD800MH.B and SSD1600MM SSDs.
Mike Cordano, President of HGST, indicated at last year's HGST Press and Industry Analyst Briefing that a 2 million hour MTBF is the trademark of HGST products. He might need to expand upon that statement, as HGST also announced that the entire range of Ultrastar 12 Gb/s SAS SSDs are now also rated for a 2.5 million hour MTBF. The usual rating for enterprise SSDs is 2 million hours, so this represents a 25 percent increase in comparison to the majority of competing products. The announcement of a 2.5 million hour MTBF for SSDs follows HGST's recent announcement that all of its helium products are also certified for the higher MTBF period.
Server side flash is a hot segment that is growing much faster than the all-flash array market. According to Gartner's latest reports, server flash sales expanded by 51 percent, and server SSD revenue weighs in at $3.9 billion. HGST has a commanding lead in the enterprise SAS SSD market, partly due to its JDA (Joint Development Agreement) with Intel. The JDA combines the experience of both companies to collaborate in SAS SSD development efforts, and it also gives HGST direct access to Intel flash. Whether the supply agreement extends beyond SAS SSDs isn't disclosed publicly.
During a recent tour of Intel's SSD validation labs at the Folsom NSG campus, we spotted several HGST SSD products (upper right hand corner of this thermal testing chamber) among the Intel products in Intel's reliability testing lab. HGST announced the new 2.5 million hour MTBF rating in Ulrich Hanson's (Vice President, SSD Product Marketing at HGST) blog post, but the post doesn't indicate if Intel was part of the validation effort. With the existing JDA between the two companies, and our past observations of HGST's SAS products in Intel's validation labs, it's safe to speculate that Intel's labs were involved as well.
HGST still has a few products in its arsenal that remain at the 2 million hour MTBF level, namely the air-based HDDs, but it appears as if the company is transitioning to providing a 2.5 million hour MTBF for all of its products as it transitions into its all-helium HDD future.

2015 Spring, PCIe SSD Roundup & Review - Samsung SM951 NVMe vs. AHCI, XP941, SSD 750
There's been a lot of recent talk about the Samsung SM951 M.2 PCIe SSD. It was supposed to launch as an NVMe product, but ended up coming out in AHCI form. We can only assume that Samsung chose to hold back on their NVMe-capable iteration because many devices are unable to boot fron an NVMe SSD. Sitting back for a few months was a wise choice in this case, as an NVMe-only version would limit the OEM products that could equip it. That new variant did finally end up launching, and we have rounded it and the other Samsung M.2 PCIe SSDs up for some much awaited testing.
These are all OEM products, but here are some specs from various sources:
Form Factor: M.2 2280
Capacity (GB): 128, 256, 512
Host Interface: PCI-Express 2.0 x4
MTBF: 1.5 Million Hours
Uncorrectable Bit Error Rate (UBER): < 1 sector per 1015 bits read
Power Consumption (Active/Idle): 5.8W / 80mW
Peak Read Sequential Performance: Up to 1170 MB/s
Peak Write Sequential Performance: Up to 930 MB/s
Peak Random Performance Reads: Up to 122k IOPS
Peak Random Performance Writes: Up to 72k IOPS
Physical Dimesions: 22 x 80 x 4 mm
Weight: 8.5g
SM951 (AHCI):
Form Factor: M.2 2280
Capacity (GB): 128, 256, 512
Host Interface: PCI-Express 2.0 x4
Controller: Samsung UBX 3-Core

Peak Random Performance Reads: 90k IOPS
Peak Random Performance Writes: 70k IOPS
Physical Dimesions: 22 x 80 x 4 mm
SM951 (NVMe):
Form Factor: M.2 2280
Capacity (GB): 256, 512
Host Interface: PCI-Express 2.0 x4
Flash: Samsung 16nm MLC (verified visually)
Peak Read Sequential Performance: 1.08, 1.17 GB/s *
Peak Write Sequential Performance 800, 931 MB/s *
Peak Random Performance Reads: 120k, 122k IOPS
Peak Random Performance Writes: 60k, 72k IOPS

Intel Shows Off New Thunderbolt 2 Products At NAB 2015
The yearly National Association of Broadcasters (NAB) show gives media professionals from multiple disciplines the chance to meet and peddle their wares. Every year, NAB spurs a flood of new product releases from a variety of vendors, and this year is no exception. NAB has it all, from enterprise storage products to the latest in displays and client storage technology.
Intel is a strong proponent of Thunderbolt technology, and it has a number of new products in its booth from multiple vendors to highlight the expanding number of Thunderbolt 2 products on the market. Thunderbolt 2 is well suited to media professionals due to its flexible nature and high bandwidth. The jump to Thunderbolt 2 actually didn't increase bandwidth, but it provides channel aggregation of the previously-separated 10 Gbps channels. This enables new capabilities, such as simultaneously transferring and displaying 4K video.
Thunderbolt users can connect up to six devices, such as 4K monitors and storage products, through a single port that carries both DisplayPort and PCIe data. What kind of craziness does this spawn? Let's start with the "world's first" 4K Thunderbolt 2 monitor.
LG Electronics 31MU97Z
LG ships five different Thunderbolt 2 monitors, but the LG 31MU97Z steps away from the pack as it's a 4K display. The 31" monitor sports two Thunderbolt 2 ports and pushes a 4096 x 2160 resolution (17:9) to the IPS panel. The display will certainly set you back a few clams, but details are sparse and LG isn't commenting on the list price or availability as of yet.
The monitor also allows a direct connection to the Thunderbolt cable in lieu of the pesky adapters or docks with DisplayPort/HDMI connections that are required with other monitors. Thunderbolt 2 works as advertised, and the capability to both display and simultaneously transfer 4K video streamlines workflows.
QNAP Thunderbolt 2 NAS
QNAP is making an entrance into an entirely new category with its Thunderbolt NAS solution. The QNAP Thunderbolt NAS features two Thunderbolt 2 ports that provide enough speed to transfer 4K video in real time. QNAP has yet to make an official announcement of the new product, so we don't have many details, but it is a compelling product because of the fast transfer speeds that rival 10 GbE.
We'll follow up with more details once they're available.
The Thunderbolt booth at NAB 2015 also has several demos, including Thunderbolt NAS, 4K content creation with card reader, and Thunderbolt networking. A bevy of Thunderbolt product releases were announced this week, including the new LaCie Rugged Thunderbolt enclosure with a 1TB SSD; the Pegasus2 R2+ RAID 0/1 media station with an included USB 3.0 port; the Sonnet Fusion PCIe Flash Drive in 256 GB and 512 GB capacities; and the m.2-powered JMR PCIe Flash Drive in 128, 256 and 512 GB capacities; among many others.
The leading-edge Thunderbolt 2 products highlight some of the new features we can expect to see in the future. As more ports make their way onto motherboards with Intel chipsets, we can expect the ecosystem to continue to expand. Thunderbolt 2 is much faster than USB 3.1, but we wouldn't hold our breath on it usurping the ol' USB standby for most external devices in the near future due to cost concerns.

Transcend Launches New eMMC 4.51 Flash Memory Chip
Transcend Information, a Taiwan-based company focused on manufacturing digital storage products, announced the launch of its new EMC210 eMMC storage solution. The flash memory chip comes with an integrated memory controller, which leads to a faster product development.
The eMMC, or embedded multi-media card products, are usually found in mobile devices such as the so-called "internal storage." Internal storage tends to have faster speeds than most mainstream SD cards on the market, and Transcend's new flash memory chip is no exception.
The EMC210 is compliant with the JEDEC 4.51 specification and offers read speeds of up to 140 MB/s and write speeds of up to 60 MB/s. This is in contrast to, for example, Samsung's eMMC 5.1-compliant memory chips that promise read speeds of up to 250 MB/s and write speeds of up to 125 MB/s.
eMMC 5.1 is the latest JEDEC specification for flash memory chips. Samsung's chips also promise 11,000 IOPS read and 13,000 IOPS write performance. Transcend didn't mention its chips' IOPS performance in its press release, but it's likely to have a significantly lower write speed.
The eMMC standard is about to be replaced by the even faster UFS 2.0, which Samsung already uses in the Galaxy S6; Xiaomi has also hinted at using it this year in its phones. However, the eMMC standard will continue to be used in lower-cost smartphones and tablets for the foreseeable future, especially considering that the biggest volume of smartphone sales is represented by low-cost devices.
It's important to note that the flash chips' speeds tend to be significantly slower in the real world, and the ones promised are more theoretical than anything else. Still, the official numbers give us a rough idea about how they compare to each other.
Trascend's eMMC solution will come in capacities of 8 GB, 16 GB and 32 GB. This, along with the support for an older and lower performance JEDEC specification, implies that the chip is meant for lower-cost devices, which don't tend to have more than 32 GB of internal storage.
Transcend's EMC210 includes a number of extra features such as Enhanced Reliable Write, which ensures there won't be any data loss in case of sudden power loss during a write operation. It also comes with Automatic Sleep Mode, which tries to put the chip in standby after a short period of inactivity to minimize power consumption.
Other features include Quick Health Info to help with monitoring the erase count of the flash, TRIM, ECC and Secure Erase. Secure Erase is a feature that can be useful for when you want to sell your phone. Data isn't completely erased when you reset/format a phone, but Secure Erase can purge all the leftover data to clean the flash chip. Details here:…/transcend-emmc-4.51-flash-mem…
