Japanese giant Toshiba said it has introduced a 600GB 2.5-inch enterprise hard drive family with some models offering self encyription.

The MBF family has a power condition state so that the drive spins slower when not in use.

The MBF drive comes in 300GB. 450GB and 600GB flavours. Each has a 16MB buffer and an interface transfer rate of 6Gb/s SAS. The units will ship in volume in April but Toshiba is already sampling the drives.
