I have both an ST157N and several ST251 (w/Adaptec 4000A SCSI translator)
drives, among others, connected to my system.  The ST157N is the MLC-0 part
(40mS) as are the ST251 drives.  Without question, the ST157N outperforms
the ST251 drives.  Significantly.

In general, the embedded SCSI controller drives really scream (even with 1.2).

Another example: Maxtor XT-3380 embedded SCSI is consistently averaging over
55KBytes/sec vs. the Maxtor XT-2190 (with Adaptec 4000A) getting ~42KBytes/sec.

tests conducted under 1.2 (with a Supra 4x4 host adapter on an A1000) using
DiskPerfA and AutoTest.

The ST157N is available in Silicon Valley for "around" $600 if memory serves;
the local Amiga dealer (HT Electronics) carries that and the ST138N in stock.
