We peformed the same upgrade, except we went to the Jamica to 8x18.2GB
drives @ RAID 1.  If performance is an issue, you definately want RAID
1 not RAID 5.  The Autoload 12H is supposed to automatically use RAID
1 if under a certian usage percent (i think 50%), and switch to RAID 5
if over.  If you then add more drives to the unit, and it decreases
below the RAID 1 maximum percent, its supposed to switch back to RAID
1 again.  The process was flawless, "EXCEPT" we needed a powerpatch
for the Autoload 12H.  Be sure your OS/patch level will allow you to
use the Autoload 12H before you start the install!

Good Luck!  --zah
