IBM presents new generations of hard drives
IBM recently presented two new hard drive series. For the desktop market the Deskstar-120GXP series and for the mobile market the Travelstar 40GN series and the high-end model Travelstar 60GH. The 120GXP series is now catching up with the competition with up to 3 disks (platters) á 40GB in terms of roof density.
The new hard disks rotating at 7200 rpm will be available in 40, 80 and 120GB increments. They will be compatible with the standard UltraATA-100 interface, i.e. they will not support the new ATA133 standard created by Maxtor and will have 2MB of local cache. According to IBM, the average access time is 8.5 ms.
The top model, the Travelstar 60GH operated with 5400 rpm, and the somewhat smaller 40GN series with 10 to will be available in the notebook market this year 40GB storage space and a rotation speed of 4200 revolutions. The average access time for both series is 12 ms, which indicates a higher data density for the 40GN disks. Both will have ABLE (Adaptive Battery Life Extender) power saving technology.
