In reply to the doctor, in part the reason for the marked difference in rotational speed (and some other features) is precisely so as to allow a differential on performance (and price).

Very often the drives in a mechanical sense are *very* similar - so (in principle a 10000-15000 rpm IDE drive should be possible). In the old days (when I was young and had somewhat more hair) SCSI drives were guaranteed to be free of defects - whereas IDE drives only guaranteed the first cylinder (the integrated controller IDE then avoided the errors using data hidden in the "engineering" track also recorded on the disk). This meant fewer IDE platters were rejected (so they could be manufactured at lower cost than there SCSI siblings).

You can also add many more SCSI devices (including drives) compared to standard IDE (IDE being 4 and SCSI either 7 or 15). SerialATA will reduce this advantage somewhat - though initially won't be able to match SCSI Ultra160 for performance (SerialATA-2 though should prove better).
