   I'm not sure if the RamFAST supports SCSI-2 drives at all. If they
can be connected with exactly the same set of conenctors, and more
importantly, they support the SCSI protocol and pinouts, they should
work.  On the otherhand, except for size, SCSI-2 is no use on the
IIGS. 

   With a RamFAST, my 13ms Quantum drive is definitely not stressed
out by disk operations. Far from that; with the IIGS's bus's 1MHz
limit, the problem seems to be the computer. When performing large
operations (verifying files/ verifying a volume/ loading large (>200K)
files/ whatever), the drive light flickers for fractions of a second
as it reads/writes large amounts of data, then waits for the RamFAST
to feed the IIGS data as fast as it can take it.
