RAID Boxes are QUITE expensive, hence the software route for data
protection.  The cost/gig is very uneffective.  Something like the AMI RAID
controller makes a bunch of disk act as a raid set and represents them as a
logical unit.  Something like a Raid box has a higher cost/gig.
	DPT has a raid module for their SCSI cards.  I have no idea about drivers
for these, as they may not exist.
