My own tests show that 15K RPM ultra 320 SCSI drives are considerably
faster than any IDE storage.
This ATA drive:

Performs as well or better than many SCSI drives, and are not terribly
expensive. Therefore, these are a very good choice if price performance
is more important than absolute performance.
But if you need absolute horsepower, then one of these (or other 15K
Ultra320 equivalent) won't be beaten:
