Dave_5280 :
Wouldn't that be true of all RAID levels except 0?
I'm going to use cloud backups.
Yes.
Delete a file on my drive, it's deleted.
Delete it with a RAID 1, it is the exact same result. Just deleted from 2 drives.
If you're going to have backups elsewhere, the RAID is really, really not needed.
If I have a few applications installed on a secondary drive, and it dies....no problem. I still have the install disks and can redo it in an hour. If I were running a webstore or something, that hour to rebuild translates into lost sales. $$$.
But for me here at home? Trivial.
The extra hassle is not worth it.
