	This is like saying that any purported benefits from ST506 are negated by
the need to translate to/from SCSI, as is done with any SCSI controller (as
opposed to an SCSI host adapter). ESDI is a controller/drive interface spec,
as are ST506 or ST412. More than likely, the lack of expected performance
improvement is due to another factor. I would suspect the Adaptec
cotroller, judging from their rather poor performance in the SCSI/St506 area.
