There is no right or wrong answer to whether or not you want an SD card. It IS
wrong to declare that there is a universal answer.
It depends on YOUR OWN PERSONAL needs.
I, for example, prefer having my 64GB SD card. Why?
1. I rooted my phone, which opens up tons of capabilities, one of which is full, local backups, which I can do in short time without using any data plan bytes. Then I can restore
from those backups, in very short order, from any backup. There's no cloud way to do that. iCloud is FANTASTIC, but you can't do a full OS backup with it and you can't have multiple backups to it and you can't use it when you're in a dead zone or slow zone.
2. Apps CANNOT run from the cloud. They MUST be installed locally. I install A LOT of apps. I use an app called FolderMount
that let's me move any folder to my SD card without screwing up apps that depend on the folder being in a certain place... It makes a fake path in the original location, so it works with all apps.
3. I don't always have access to high speed data.
4. Security: There are some files that I don't want on the cloud. I do back them up to my PC though, but I don't want them on the cloud.
There ARE plenty of legitimate reasons to use SD cards. They are NOT 100% functionally interchangeable with cloud storage. Both cloud and SD storage have their pros and cons. That's why i use BOTH and for somewhat different reasons.
I currently have unlimited data, but not everybody does, so cloud storage just isn't a realistic option in some of those cases nor is it a realistic option for people that are frequently in dead zones or low speed zones. And, if you can have it all locally, immediately, well, I can't see a downside. Of course, as always, make sure you also
back it up, either to another device you own or to the cloud or both.
But, if cloud storage meets your needs, then more power to you. I love cloud storage too, that's why I have an account on all of the popular cloud storage services and I use them.
