Remember you should also have backups.. Many people make the mistake and 
assume that RAID is a substitute for a good old fashioned backup.. So in 
the unlikely event that you loose 2 disks in a RAID 5 array you should 
still have the data availible on another source..

Personally I run RAID in Server A, B and C, rsync the important data 
from Server A, B and C to Server D (also RAID) and from their backup all 
the synced data to tape.. Server D does not have to be a big expensive 
server either.. I use an old Compaq Deskpro P2 400 with lots of drive 
space (enough for all the synced data anyway) and a DAT drive..

Don't know if that helps anyone..
