?????? RAID1 can only handle 1 failure also!!
If you are a decent administrator, you'll act when a disk becomes flaky, or as soon as it fails. (Of course, if 2 disks go at the same time, you're hosed, but that's the case for RAID1 also...)
Hmmm, probably I wasn't very clear.
What I mean here is that if you stuff an array of 10 RAID 5 disks the chance that two disks will fail at the same time will be quite high.
Much higher than with two mirrored disks. So, statistically, a small array is safer than a big one.
Moreover if two disks in an array of ten fail, you will lose the content of nine disks. If a mirrored pair fail you lose just one disk.
I would say that the use of a spare disk is recommended in any case. ;)
