It's been a while, but I think that RAID originated in academia, though Cray 
may well have been one of the earlier commercial users.

What I was referring to wasn't RAID but rather single drives with parallel 
(multiple tracks concurrently) transfer, just like the 807/808.  Does that ring 
any bells?
