I disagree that the data xfer rates of a IIgs SCSI card are higher than
that of any Mac except the Mac2.  Probably the transfer rates of any mac
are >2X faster than the II.  The scsi card can handle a 3:1 interleave
barely.. (Due to on board ram to buffer things)  The company I work for
builds fast drives on the Mac, sustainable transfer rates of 1.4 MBytes
per second on a Mac2.  I think people to watch the access times because
date throughput is so slow on the II.  On the other hand, Prodos's
file/directory management is so disk intensive, a faster access time may
help.  One thing nice about Apple's SCSI drives is that you need not
use a foreign formatter to format the disks.  3rd party scsi drives need
custom formatters, which no doubt will need maintenance with future
ROM/OS updates.
