Subject: IDE vs SCSI drives

\_ 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.
