You might want to look at products available from Core International; 7171 N.
Federal Highway; Boca Raton, FL 33431; (305) 997-6055.  They have fast drives
(down to 15ms, I believe) and ESDI controllers (which operate at 10 Mbits/sec
instead of 5).  I haven't timed the combination, but I have used it and it
makes a significant difference.  You should also try a disk optimizing program
(if you haven't already).  Fragmented disks can run very slowly.
