i am looking to by another disc drive and i would like to know which
will give you better performance, an HPIB disc drive (using a
high-speed HPIB of course) or a SCSI disc?  i believe that there are
two types of SCSI controller cards: asynchronous and synchronous.

from what i know a high speed HPIB has about 1meg/sec bandwidth, the
async SCSI has 1.5meg/sec bandwidth and the sync SCSI has 4meg/sec
bandwidth.

will the synchronous SCSI really be that much faster?  will the disc
actually transmit data that quickly?  can a HP9000/370 receive data
that quickly?  does anybody have a recommendation on a _fast_ disc
that has >150meg.  (preferably 300meg or so)
