The Hitachi Travelstar™ 7K200 is the Industry’s only third-generation 7200 RPM notebook hard drive. It delivers double the capacity and a 22% performance improvement over its predecessor. At 200GB, Hitachi offers the highest capacity 7200 RPM 2.5-inch product with unmatched performance in PCMark testing. Despite the higher spin speed, the 7K200 offers comparably low power consumption, heat emission and acoustics to its 5400 RPM counterparts, so users don’t have to trade off battery life or audio quality for high performance. In addition, with its new higher shock specifications, and optional Bulk Data Encryption on specific part numbers, Travelstar 7K200, is designed for the most discriminating notebook users.
