Toshiba today announced a new line-up of 1.8-inch hard disk drives (HDD) adopting a serial ATA interface, including a model with a capacity of 160 gigabytes.

The new 160GB drive, MK1617GSG, and an 80GB drive, MK8017GSG, will enter mass production in August.

Toshiba's new 1.8-inch HDDs boost interface speed to 1.5Gbps and offer a rotation speed of 5,400 rpm, faster than the current generation of Toshiba 1.8-inch HDD (MK1214GAH, parallel ATA, 120GB).

The new MK1617GSG drive is more environmentally efficient than Toshiba's current MK1216GSG (120GB) model, and raises energy consumption efficiency, as defined under the Japanese legal standard, to 0.00281W/GB, a 25% improvement. The drive improves the maximum internal data transfer rate by approximately 17%, and supports faster data access in reading and writing.

In additon, compared to current 2.5-inch HDD (MK1652GSX), the new drives offer the higher levels of vibration and shock resistance needed in mobile PCs.
