The Hitachi Travelstar 5K500 will begin to ship in February 2008, maxing out at 500GB â€“ half a terabyte â€“ making it the largest capacity mobile hard drive in the 2.5-inch diameter league. The Travelstar 5K500 will retail at $400, with a 400GB version at $350.
Previous 2.5-inch HDD record holders include Fujitsu with 300GB and Toshiba with its 320GB drive. Hitachiâ€™s pole vault to 500GB is a 36% increase in one leap.
To get to 500GB, Hitachi adopted a 3-platter design, departing from the usual two-platter tango for a 2.5-inch drive. It also incorporates Hitachiâ€™s RVS technology, or Rotational Vibration Safeguard.
Already, Asus of Taiwan wants the new Hitachi drives. The notebook maker plans to offer the 500GB drive in a striped RAID configuration to provide 1 terabyte of storage, a 1TB notebook PC!
