#Novachips 4TB / 8TB SSD Review – HLNAND Sees 8TB Sizes & Higher, Speed & Low Power
#Size, #speed, #reliability, and #value are the variables that have determined SSD #success since it’s introduction back in 2007. Today’s consumer can buy a SSD with blistering speeds of 2.5GB/s, another with 2TB of storage, both will last longer than their need requires, and now we can find prices at or below .25/GB. Two things still create a bottleneck in SSD capacity though, these being the mechanics of today’s SSDs along with flash pricing. Novachips hopes to tackle this with the introduction of their Scalar family of 4 and 8TB notebook size SSDs, now available to oem, enterprise and even the consumer.
NAND pricing aside, the difficulty with producing a higher capacity SSD has been the fact that higher volume chips were not yet available and too many memory chips were required to make a #notebook SSD feasible. In result, multiple controllers would be required to power so many chips, as well as ensuring an adequate level of performance for the #SSD
. Add to this the fact that the inevitable heat would make the idea of containing 4TB, much less 8TB of storage within a notebook solution unrealistic….that is until Novachips engineered a new memory solution called #HLNAND (or #HyperlinkNAND).
This report will demonstrate both the Novachips Scalar Series 4TB and 8TB SSDs and both are 2.5″ SSDs, the 4TB being 7mm in height while the 8TB is 15mm. Both contain a single SSD controller, present no additional heat concerns than we might experience from a typical SSD, and both are 6Gbps SSDs that perform at the top of the SATA 3 bandwidth. This is something that we have never seen in any similar capacity prior, short of Samsung’s recently announced #enterprise only PM1633a. The PN1633a is a 16TB SAS SSD that has never been seen in the wild and will never be available outside of large quantity enterprise purchase. Also, stay tuned because before long, we we will have the Novachips NVMe SSD in our hand, capable of 1.5GB/s and 16TB of storage space.
SPECIFICATIONS AND #WARRANTY
Novachips Scalar SSDs are SATA 3 SSDs and are available in 2, 4 and 8TB capacities right now. All are capable of 520MB/s read and 500MB/s write throughput with up to 70K random read IOPS and 80K random write. Power consumption is listed at up to 6.09W (active) and 2.73W (Idle) average for the 8TB version and all have 256-Bit AES encryption which may be enabled, as well as thermal protection and power loss data protection. Reliability is listed at 3,900TBW and the Scalar comes with a 3-year limited warranty. Initial pricing has just been released at $2499 for the 4TB and $4999 for the 8TB and immediate purchases can be made at the Novachips Shopify website.
WHAT IS HLNAND?
In its simplest form, HLNAND is much like Thunderbolt in many ways. It uses a daisy-chain, or ‘Ring’ topology to connect memory chips, much unlike the present parallel bus architecture that is very limited.
Up to 255 memory chips can be connected in the ‘Ring’ and each only connects to the next, meaning that each only receives and transmits a single load. Each module shown in this below left diagram can be broken down to 4 banks and the HLNAND interface as we see to the right of that.
Because of this single load transfer, memory speed is maintained throughout the ring and power requirements are significantly lower than that of a multi-controller parallel bus architecture.This then results in significantly less heat as well. Now consider the capacity in this AIC, considering that each module in the sample can now be 256GB of RAW storage, and all chips running into a single controller design.
THE NOVACHIPS NVS3800 CONTROLLER
Novachips NVS3800 controller (Codename Bugatti 2) is Novachips second generation proprietary design and is based on 28nm low-power technology. It is a quad-combo single chip ARM-based eight channel controller and capable of supporting four different hardware combinations, SATA, PCIe, ONfi or Toggle NAND, or HLNAND. It’s maximum SSD capacity is 32TB and the maximum supporting NAND channel speed is up to 400MB/s (ONfi/Toggle) or up to 800MB/s (HLNAND).
Our SSD Quick Search on the left tab of this page enables a search of similar SSDs with the same components and reviews, along with links to Amazon for a price check.
The Novachips NVS3800 supports all modern memory sizes (1y/1x/2x/3xnm) and types (SLC/MLC/TLC/ONFI/TOGGLE) as well as Novachips own HLNAND. It supports AES 256-Bit encryption, TCG OPAL 2.0 and even DEVSLP in SATA mode. The only hiccup (and it really isn’t considering their target sales) is that the maximum storage capacity available for all except HLNAND is 1TB, whereas, it is 16TB with HLNAND.
BREAKING DOWN HLNAND
HLNAND is not a new type of memory bore from silicon wafers that are in the control of Novachips, but rather a total package comprised of NAND components and a HL (Hyper-link) bridge.
n the case of both of these SSDs, each NAND module contains 16 NAND dies stacked, each of these being SK Hynix 16nm 128Gbt MLC NAND flash memory. The total RAW capacity of each memory module is 256GB. Now to break down NAND packages and channel structure, the 4TB Scalar SSD uses 8 channels x 2 packages per channel (16 packages x 256GB=4TB) while the 8TB Scalar SSD utilizes 8 channels x 4 packages per channel (32x256GB=8TB).
And for the more technically minded, HLNAND adopted Intelligent Packet-based Chip-Select (IPCS) technology over the old-style CE# (Chip-Enable #) based Chip-select, which is selecting NAND dies in ONFi or Toggle system. IPCS technology does not require physical CE# signals which are responsible for much signal-integrity headaches and takes too much PCB area for large capacity SSD design. IPCS technology is, however, based on the existing data packet concept which is sharing 8-bits of DQ signals for Command/Addressing/Data transaction for NAND flash access, by simply adding “Device ID/Bank Address/LUN Address” in front of every Command Packet.
NOVACHIPS HLNAND SSD COMPONENTS
We have both the 4TB and 8TB versions of the NS370 in hand. Both are 2.5″ notebook SATA 3 SSDs with the 4TB version being 7mm thick while the 8TB version is 15mm thick. The increased thickness of the 8TB version is due to the dual PCB design. Both are encased in a two piece aluminum exterior and secured with 4 screws. This is the 4TB PCB and it contains the NVS3800 flash processor, 16 pieces of HLNAND, and two Samsung DRAM cache memory chips
The 8TB Novachips Scalar NS370 contains a dual PCB combination of which the first PCB contains the NVS3800 flash storage processor, two Micron DRAM cache memory chips, and 16 pieces of HLNAND memory (HL7G2T44BHBB) with each piece containing 256GB of RAW memory, for a total of 4TB.
The second PCB also contains 16 HLNAND flash modules, but also contains 40 power capacitors (20 on each side) for complete power loss data protection. You might notice that the Novachip Scalar 8TB has a whopping 40 power capacitors (20 front and back of daughterboard) compared to the 4TB version which has significantly less, three in fact. Novachips assures us that regardless of capacity, the user is fully protected against data loss should a power failure occur.
