Product info

Toshiba Storage Device Division introduces a range of high performance 2.5-inch hard disk drives for mobile applications. With a rotational speed of 7200 rpm and a fast media transfer rate of up to 1,020Mbits/s, this new series offers the best solution for every notebook expectation and function.

The MKxx54GSYF series is available in storage capacities from 80 to 320GB, making it ideal for a wide variety of applications demanding performance. The new drives incorporate the latest Serial ATA technology and support a 3.0 Gbit/s interface data transfer rate.

Furthermore, the new drive incorporates Free Fall Sensor technology. This technology uses an embedded motion sensor to detect if the drive is in free fall. In such cases, the HDD quickly and immediately moves the read/write heads away from the spinning to prevent them damaging any data upon impact.
