I still have another 500 or so messages ahead of me, but I figured I
would answer this one before I forgot about it.

I have a Starboard with a ST-157N.  Running Diskperf on a nearly empty
partition give me read values of about 190K/sec.

Microbotics includes a command called FASTMODE (or some such name; I
can't remember now and I'm typing this on a MacII instead of my Amiga)
that pulls some shortcuts on the SCSI protocol and speeds up transfers
by a factor of two or so.  The only restriction is that you cannot be
in FASTMODE when you low-level format the drive.

You can also specify FASTMODE directly from the mountlist.  You have
to change the

Flags=

value to 12336 (which is from memory and could be wrong -- I'll check
the next time I'm in front of my Amiga).
