Toshiba announces dual-platter, 1TB mobile drive

Following in the footsteps of Samsung and Western Digital, the folks at Toshiba have introduced a dual-platter, 1TB mobile hard drive. Because it uses only two platters, the drive is able to conform to the 2.5", 9.5-mm form factor that guarantees compatibility with most of today's notebooks.

The MQ01ABD has a 5,400-RPM spindle speed, 8MB of cache, a 12-ms average seek time, and a 3Gbps Serial ATA interface, so it shouldn't break any speed records. Nevertheless, the platter density (500MB for each platter) ought to compensate for the sluggish rotational speed to some extent. Samsung's and WD's 1TB, dual-platter drives don't spin their platters any quicker, for the record.

According to Toshiba, the MQ01ABD will hit mass production in the middle of this month. Alongside the 1TB model, Toshiba plans to offer 750GB, 500GB, 320GB, and 250GB variants with otherwise identical specifications.
