A new family of small form factor 2.5-inch {6.4 cm} hard disk drives has been announced today by Toshiba Electronics Europe. Packing up to 1TB in a drive that measures just 7mm in height and designed for silent operation and low power consumption, the MQ02ABF series are ideal or use in ultrathin laptops and thin PCs.

A thinner mechanical structure containing a new 5,400 RPM spindle motor is housed within a newly designed rigid chassis that keeps noise levels to 22dB during idle and 23dB during seek operations. Average drive ready time is just 3.0 seconds (typical) and average seek times are 12ms.

The MQ02ABF100 has a capacity of 1TB and the MQ02ABF075 a capacity of 750GB. Both drives are equipped with two storage platters and four data heads furnished with dual-stage actuators (DSAs).

The MQ02ABF series drives are supplied with 16MiB^[2] of buffer memory and high-speed Serial ATA 3.0 (SATA 3.0) intelligent interface controllers with maximum operating speed of 6,0 Gbit/s.

The drives have an operational temperature range of 0-60°C (ambient) and can withstand shocks of up to 3,430 m/s² {350G} while in use. Sample shipment of the new family of high-capacity, slim HDDs is scheduled to start in November.
