640GB Toshiba 2.5-inch SATA laptop hard drive (5400rpm, 8MB cache) by Toshiba

Toshiba's MK6459GSXP Serial ATA hard disk drive targets today's massive digital storage needs with a 5,400 RPM spin speed, 640GB storage capacity point and a standard 2.5-inch form factor. The compact MK6459GSXP drive is designed for notebook PCs, all-in-one desktops, slim line workstations, external add-on storage devices and other capacity-hungry applications. The power efficiency characteristics of the MK6459GSXP make the drive well-suited for Energy Star® and battery-conscious products.

Toshiba's MKxx59GSXP series of 5,400 RPM hard disk drives is a long data sector counterpart to the MKxx76GSX line-up. Both product series build upon the maturity of the Toshiba 320GB* per-platter architecture to offer the same big storage capacities with a technology boost to enhance quality and span 160 to 640GB. The MKxx59GSXP series uses Advanced Format (AF) technology where data is stored on the media in 4,096 bytes per sector increments. Compatibility with legacy, 512 bytes per sector applications is maintained through AF emulation techniques, called 512e. The large storage capacities, ruggedness and cool operation of the MKxx59GSXP models are well-suited for mobile and compact, stationary applications. Their massive storage capacity and energy efficiency also make the MKxx59GSXP line an attractive, space-saving alternative to desktop hard drives. Power consumption can be reduced by more than 80% over like-capacity 3.5-inch hard disk drives. While reducing or eliminating the use of certain toxic, hazardous or controversial chemicals and materials in the drive, the MKxx59GSXP series is ideal for Windows® 7 and Mac® OS-based notebook, all-in-one and EnergyStar® desktop PCs, external storage devices and other computing.

Thickness of this hard drive is 9.5mm.
