Toshiba MG – a High-Capacity, Business-Critical HDD Series

The 3.5-inch drives work in NAS, SAN and tiered storage systems

The winter holidays may be a time when consumers take precedence in IT companies' eyes, but that didn't stop Toshiba from finishing and launching its newest enterprise storage product line.

There are four new hard disk drive units that Toshiba has introduced, all of them aimed at NAS (network-attached storage), SAN (storage area network) and tiered storage deployments.

Their capacities are of 1 TB, 2 TB, 3 TB and 4TB, respectively, and the name of the series is Toshiba MG.

All four have a platter rotary speed of 7,200 RPM (rotations per minute) and 64 MB of DRAM cache memory (buffer memory as it were).

The 4TB drive has five platters in total and 18% faster transfer rates compared to previous-generation business-critical HDDs (up to 165 MB/s).

Basically, large enterprises should easily be able to integrate Toshiba's new magnetic storage devices in their various storage arrays, including direct-attached applications in general purpose servers and SMB systems.

“Organizations of all sizes continue to be challenged by the exponential growth of big data and information they need to protect and maintain,” said Joel Hagberg, vice president of marketing at Toshiba Storage Products Business.

“Toshiba’s new 4TB drives provide the high-capacity and enterprise-class reliability required to keep up with rapid data growth.”

Toshiba's MG product series includes some optional SATA self-encrypting models with support for secure cryptographic-erase. The T13 Sanitize crypto-scramble protocol and the older T13 ATA Security Erase command protocol are used.

Meanwhile, the optional SAS SED models get the T10 Sanitize crypto-erase feature and the Trusted Computing Group enterprise security sub-classification protocols.

These technologies quickly and completely erase user data beyond any chance of recovery, so that devices may be retired or redeployed easily and safely.
