MK6015GAA
Komerèní informace
Toshiba Storage Device Division představuje nový pevný disk 1,8'' 60 GB - MK6015GAA. Jednotka MK6015GAA používá rozhraní ATA-4 a podporuje rychlost přenosu dat 66 MB/s. Došlo zde ke zvýšení standardní hodnoty 512 bajtů dat na sektor na hodnotu 1 kilobajt, což je potřebné pro řídicí struktury, informace nutné ke správě jednotky, vyhledávání dat a vykonávání dalších funkcí. Z důvodu snížení hladiny hluku a zamezení snížení akustické kvality disponuje jednotka 3600 ot/min.
Tato nová jednotka byla navržena výhradně pro ultrapřenosná spotřební elektronická zařízení. Vyznačuje se vysokou plošnou hustotou, nízkou spotřebou energie, nízkou akustickou hlučností a kompaktními rozměry 54 x 71 x 5 mm.
