STORAGE VENDOR Toshiba has launched 4TB self-encrypting and data scrubbing hard drives.

Toshiba, which has picked up part of Western Digital's business, announced four enterprise models that use the SATA 3 and SAS 2 interfaces. The Japanese firm's headline units sport 4TB capacity by spinning five platters at 7,200 RPM.

Toshiba offers standard versions of each model, which range from 1TB to 4TB in 1TB increments, and a premium line that features hardware data encryption and data scrubbing protocols. The drives have a 64MB buffer and an average seek time of 4.17ms, however the most important specification is a five-year warranty on both the standard models and those that feature hardware data encryption and data scrubbing.

Toshiba claims its MG series hard drives have power management firmware that allows them to consume less power during idle periods. The firm claims an 18 percent increase in the hard drives' sustained data transfer rates, which are 165MB/sec for the 4TB model, dropping to 155MB/sec for the 1TB, 2TB and 3TB models.

Joel Hagberg, VP of marketing at Toshiba Storage Products Business said, "Organizations of all sizes continue to be challenged by the exponential growth of big data and information they need to protect and maintain. Toshiba's new 4TB drives provide the high-capacity and enterprise-class reliability required to keep up with rapid data growth."

Toshiba said that samples of its MG series hard drives will ship in December with volume shipments starting early in 2013. µ
