Podporován jako standardní SCSI disk, netřeba nic nastavovat.

Poznámka

# hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   5472 MB in  1.99 seconds = 2744.96 MB/sec
 Timing buffered disk reads:  164 MB in  3.03 seconds =  54.13 MB/sec

V současnosti (listopad 2007) jde o největší běžně dostupnou velikost 2.5" disku. Začínají se již ale objevovat větší exempláře s velikostí 300 GB. Tento konkrétní model je podle Tom's Hardware nejrychlejším 250 GB 2.5" diskem na trhu.

S výsledky testu plně souhlasím a potvrzuji, že disk se v systému chová mimořádně svižně. Dále je velmi příjemná jeho hlasitost, není totiž slyšet ani když systém zuřivě hrabe na disk a kontrolka aktivity se může ublikat
