Sui dischi sono stati condotti test prestazionali al fine di verificarne il comportamento. Ottimi risultati sono stati ottenuti dall'unità Fujitsu; suoi i migliori risultati nel test Iometer di Intel.<BR>
Ovviamente stiamo considerando solo i dischi a 10.000 giri, escludendo il modelllo Seagate da 15.000 giri al minuto in quanto appartenente ad un'altra categoria. Non ha brillato l'unità di IBM; si tratta però di un modello ormai datato, il cui sostituto è atteso nelle prossime settimane.
