Hitachi Unveils First Terabyte Hard Drive
Hitachi Global Storage Technologies announced the industry's first terabyte hard drive. Hitachi's Deskstar 7K1000 will begin shipping to retail customers in the first quarter of 2007 at a suggested retail price of $399 (USD).
Along with the Deskstar 7K1000 for the retail market, Hitachi also announced a CinemaStar version 1TB hard drive, which provides optimized capabilities specifically designed for digital video recording (DVR) applications. The CinemaStar 1TB hard drive will be available in the second quarter.
The 3.5-inch, 7200 RPM Parallel-ATA/Serial-ATA hard drives are built on the perpendicular magnetic recording technology, first established with Hitachi's Travelstar 2.5-inch and 1.8-inch product lines.
Finally, an enterprise version of the TB drive designed for lower duty-cycle, high-capacity enterprise environments is currently under evaluation at major OEM customers and is expected to be available in the second quarter.
