A good scsi controller (like the 2842) has swapping properties looking like this
CPU: humm need to swap CPU: queue this page, this page this page... controller - go do it DISK: OK
IDE is
CPU: humm need to swap CPU: this page DISK: data ? CPU: copy copy copy copy copy copy
So while IDE may be very fast all the time one process is swapping out isnt available to others (which is very bad as busy processes swap idle ones out)
Note that the triton IDE is far far better.
