SCSI controllers at this point are easier to hang other devices on (such as
a tape drive) but seem to be slower.  ESDI drives are faster but you'd need
another controller card if you use a high-capacity tape backup system.

There seems to be no cost difference between the ESDI and SCSI versions of
the same drive.

I'm using an Adaptec 1540A controller with CDC 340MB SCSI and 660MB 
Micrpolis SCSI drives and a Cipher 150MB streaming tape.  Although there
is an MS-DOS partition on the primary drive (CDC) the system runs under
SCO XENIX V 2.3.3 almost all of the time.
