Toshiba today released four new large capacity nearline
hard disk drives (HDDs), including the first
self-encrypting models in the company?s enterprise
capacity-optimized storage lineup.
The 3.5-inch 7,200 rpm MG Series includes both SATA
models - the MG03ACA400 and the MG03ACA400Y - and SAS
models - MG03SCA400 and the MG03SCP400 - and all
deliver 4TB of storage, the company's largest capacity
to date.
The high capacity of the MG Series is suited for RAID
storage and arrays, tiered virtual infrastructures for
public and private cloud deployments, archives, and
disk-based backup and data protection solutions.
Utilizing Toshiba's latest five-platter mechanical
design, the new 4TB models provide a 100 percent
increase in capacity over Toshiba's prior
business-critical models while improving the
power-profile and operational efficiency in the
industry-standard 3.5-inch form factor. The new 4TB
models also deliver an 18 percent increase in sustained
transfer rates for both the SATA and SAS interface
versions. In addition, the MG Series includes power
management features designed to reduce power
consumption during off-peak activity periods.
The optional SATA self-encrypting (SED) models support
fast and secure cryptographic- erase using both the
latest T13 SANITIZE crypto-scramble protocol and the
older T13 ATA Security Erase command protocol. The optional SAS SED models support both the T10 SANITIZE
crypto-erase feature and the Trusted Computing Group
Enterprise Security Sub-Classification protocols. These
security technologies support "nearly instantaneous"
cryptographic-erase of user data to enable fast and
secure device retirement or re-deployment. Using SEDs
can eliminate the need for lengthy data overwrite
cycles and reduce IT department expenses associated
with secure data destruction and device sanitization.
Toshiba will start delivering samples of the MG 4TB series models in December, with volume shipments scheduled to begin early next year.
