Toshiba Storage Device Division's MKxx65GSX range of 2.5-inch hard disk drives provides optimum mobility, unparalleled performance and increased storage space for the digital user constantly on the go.

Compared to similar 3.5-inch drives, the power consumption and heat dissipation are reduced by over 80%. These drives incorporate the latest Serial ATA technology and support a 3.0 Gbit/s interface data transfer rate.

All drives within the MKxx65GSXF family are with a Free Fall Sensor technology. This technology uses an embedded motion sensor to detect if the hard disk drive is in free fall. In such cases, the HDD immediately moves the read/write heads away from the spinning platter to prevent them damaging any data upon impact.

The MK family of Serial ATA drives offers extreme power efficiency and superior operating acoustics over 3.5-inch drives for today’s high-end notebook PCs, gaming laptops, and mobile workstations as well as Energy Star® all-in-one and slimline desktop PCs.

Toshiba combines greater power efficiency of the MK drives with other environmentally-conscious solutions including RoHS-compliance and utilization of components that reduce PVC (polyvinyl chloride) and BFRs (brominated flame retardants)

An optional free-fall sensor responds to drop events and securely locks the recording heads in place off the media before system impact. This provides an additional level of ruggedness and durability to the drives and is particularly suitable for mobile applications.
