Toshiba Launches 500GB 7200RPM Notebook Hard Drives


Toshiba last Thursday unveiled a new line of performance-oriented 2.5-inch notebook drives that purport to offer the best of both worlds: Performance and capacity.

Available in 160GB, 250GB, 320GB, and 500GB capacities, Toshiba's new MKxx56GSY series promises "significant performance improvements" over the company's previous generation of 7200RPM drives. Just how much faster are they, you ask? Toshiba claims the new series offers a 23 percent boost in data transfer speeds at 1,255MB/s, while also raising energy efficiency by 28 percent.

The gains come courtesy of improved magnetic head and disk layer technology, which paved the way for an areal density of 395Gb per square inch. Other specs include a 16MB cache buffer, 25dB noise levels during both idle and seek, and 11-12ms average seek times.

Toshiba didn't announce any pricing info, but did say it plans to start mass producing the new drives in October, 2009.
