Hitachi's One Terabyte Hard Drive
May 7, 2007 Hitachi’s Deskstar 7K1000 http://www.hitachi.com/
, announced at CES 2007 as the world’s first one-terabyte hard drive has now been shipping for a month and inventories have reached critical mass. With a suggested retail price of US$400, the drive offers colossal storage capacity and is well-suited for high-performance, gaming and media center PCs and external storage devices. The drive uses perpendicular magnetic recording technology, allowing Hitachi to extend capacity beyond that available in current products. The hard drive features a 3.0Gb/s Serial-ATA (SATA) interface and large 32 MB data buffer to provide the performance required for high-end PC applications. Along with the Deskstar 7K1000 for the retail market, Hitachi has launched the CinemaStar version of the 1TB hard drive, which provides optimised capabilities specifically designed for digital video recording (DVR) applications.
Leveraging a track record for reliability from previous-generation products, the Deskstar 7K1000 hard drive is built using a 5-platter design with relaxed areal density for greater reliability. To further ensure data integrity, the hard drive features a ramp load/unload design to increase shock protection and Thermal Fly-height Control (TFC) to maintain a consistent fly-height during the read/write process.
CinemaStar specifications will be available at the time of product shipment – see Legend Performance Technologies http://www.legendcorporate.com/
