Technical Specifications:Hitachi wrote:SAN JOSE, Calif., April 4, 2006 – Hitachi Global Storage Technologies ( Hitachi) today announced two new 3.5-inch hard drives that extend the company's long-standing tradition of performance and capacity leadership. The Deskstar® T7K500 and Deskstar 7K160 feature 7,200 RPM spin speeds and 3Gb/s SATA interfaces to deliver maximum performance in mainstream and high-performance PCs, gaming systems and low duty cycle servers. The new drives use 160GB+ per platter technology to deliver up to one-half terabyte (500GB) of storage capacity in a one-, two- and three-disk design. The reduced platter count and proven Deskstar design platform optimize the drives for high-volume manufacturing and streamlined product qualifications.
