Toshiba annonce par communiqué de presse mettre sur le marché le premier disque dur à double plateau de 1,8 pouces avec une capacité de stockage de 240Go: Il est notamment destiné au PMP (Portable Multimedia Player), caméscopes et Mobile PC (120Go par plateaux)
Le constructeur japonais a également présenté des versions de 120Go (MK1231GAL) et 80 Go (MK8031GAL). Tous ces disques tournent à une vitesse de 4200rpm, ce qui en fait toutefois des disques plus lents que les dernières générations intégrées dans les Tablet PC; en effet le HP EliteBook 2730p intègre des disques durs à 5400 tours/min mais limités à 120 Go
