Not too mention it is a lot more common to accidentally delete a file,
than to have a hard drive fail. RAID doesn't protect from that either.

Probably the nicest thing about using RAID is that a single hard drive
failure can be recovered from very rapidly. (I.e. you don't need to wait
for a replacement drive to show up before ou can use your computer again.)
