Raid is backup right?
of course /s
It protects against drive failure. That is the threat I am most worried about, so it's fine for me.
Perhaps unintended but very much relevant singular. Unless you're doing RAID 6 or the like, a simultaneous failure of two drives still means data loss. It's also worth noting that drives of the same model and batch tend to fail after similar amounts of time.
This is why when you buy hard drives, you should split the order across several stores rather than buying all of them from one store. You're much more likely to get drives from different batches.
Oh, don't worry they're a random mix of old drives I had lying around, they're most certainly not the same model, let alone batch!
(But yes, fair call if you have a big Nas. I have 2TB in my desktop)
