Built for Failure

[Brian Cluff]

How many drives are you talking about using.  If you have a bunch of 
them, like 6 to 9 drivers, you could combine them into
2 or 3 groups of roughly equal size and then make a each chunk a RAID 0 
and then RAID those chunks up with either RAID1 or RAID5/6 depending on 
how much redundancy you want.   You could also reserve a couple of 
drives as spares if you wanted then to be able to automatically rebuild 
the drive if any of the drives fail.
