Hitachi Ships The One Terabyte Hard Drive


Hitachi today announced that it has met its commitment to begin shipping the world's first one-terabyte hard drive (HDD) to retail customers within the first quarter of 2007.

The Deskstar 7K1000 began shipping to retailers and e-tailers in March 2007 with inventories reaching critical mass in April 2007. It's suggested retail price is $399 (USD).

The Deskstar 7K1000 hard drive is built on the 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.

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.
