But the controllers and subsystems are completely different.  Little CPU usage
by SCSI and almost 100% by IDE,  multiple queueing of requests rather than
single request at a time.

I will, performance when used lightly does not look at all aspects.  Speed
alone measurements only strengthen my argument.  Total thru put is much more of
an issue in a server.
