Spinning and flash.
FLASH! AAAAAAAA
The world needs those two gifs combined so we can more easily (and awesomely!) answer this question in the future.
Why does it need to be two types? Can't I have 2 spinning?
You put them in a safe. Safe falls down, spinning is gone.
You put them in a safe and forget about them for some time. Flash is gone, spinning still has data.
Good point!
You can do two spinning but then you should at least use drives from different manufacturers to reduce the risk of them failing at (roughly) the same time.
if you have off-site backup, that could potentially count as the two types, but probably not in the spirit of the backup.
I have two spinning disks, a SATA SSD cache, and off-site backup
