Thanks for this information. I will have to look closer at RAID 6 for
my new file server.
Naturally, in order to provide the additional redunancy, you sacrifice
more disk space. In a RAID5 set, the parity is stored on the equivalent
of the volume of one disk. Your available space is N-1, where N is the
size of the smallest disk used. In RAID6, the available space is N-2.
The additional redundancy is good if you have a large set of disks, but
if you've got just three, it's probably overkill. RAID5 is the best
solution for a 3 disk set.
