I see you've dealt a bit with those rare creatures (in my world at least).
The most expensive I've bought so far was a 170GB SCSI3-160 drive a few years
ago. It does still run, but was to small for what we needed it to. Some time
ago we bought a used HP server with a 6x 32GB raid array. I had exchange those
for 6x 73GB SCSI3-360 SCA drives. Those six drives still cost less than that
single 170GB drive. In this case this was RAID as it was meant to be,
relatively inexpensive. 8-)
