\_ I should have mentioned this before.  The SCSI drive is *supposed* to
\_ be the faster drive.  It's a 7200 RPM drive whilst the IDE drives are
\_ only 5400 RPM drives.  When I bought these drives, I *really* did
\_ not expect them to perform better than my SCSI drive.

\_ I don't understand what you mean by the 1-1 pairing bit.  At the moment,
\_ there's only one disk on the SCSI bus.  It's the IDE drives which are
\_ mirrored.

SCSI is designed for 

1 adapter -> N devices

IDE is happier when

1 adapter -> 1 device

I bet if you do  ide_adapter -> 4 devs and scsi_adapter -> 4 devs,
you'll see a significant favor in scsi.

Craig: IIRC is available from the jargon file, AFAIK.   Still like the
'Big Room' the best.
