Toshiba Releases Updated 4TB, 6TB and 8TB HDD Models

Toshiba has released its MG08-D Series HDDs, designed for a wide variety of business-critical applications in data center environments. Use cases may include email and CRM (Customer Resource Management), data analysis for business intelligence, small-medium business servers, and data-retention and compliance archiving.

Toshiba’s 7th generation air mechanical design would provide better power efficiency and a lower component count to deliver better total cost of ownership than its earlier generation models.

The new MG08-D Series features 4TB, 6TB and 8TB HDD models, in both SATA and SAS interfaces. The new 4TB models are available in 512e, 4Kn and 512n sector HDD models. The 6TB and 8TB HDD models are available in 512e and 4Kn sector models, assuring plug-and-play interoperability for applications using prior 4TB models.

Toshiba’s new MG08-D Series delivers new levels of reliability and power efficiency to enterprise and business-critical server and storage platforms,” said Scott Wright, Director of HDD Marketing for Toshiba America Electronic Components. “Toshiba’s 7th generation conventional mechanical design utilizes Conventional Magnetic Recording technology to deliver plug-and-play versatility that is compatible with the widest range of applications and operating system environments.”

The MG08-D Series provides many industry-standard features, including 7200rpm performance, a 3.5-inch form factor, choice of SATA 6Gbit/s or 12Gbit/s SAS Interface, and a 550TB a year workload rating.

Enhanced Transfer Speeds

Compared with Toshiba’s current line-up of 4-6-8TB models, the new 4TB model would achieve the broadest range of benefits from the MG08 generation of technology advances. For example, compared with the previous model, the new 4TB would provide an approximately 23% better maximum sustained transfer speed of 243MiB/s and doubles the cache buffer size to 256MiB, according to Toshiba. It would also improve the calculated reliability specification from 1.4 million hours MTTF (AFR 0.63%) to 2.0 million hours MTTF (AFR 0.43%), and reduce active idle power consumption to 4.07W. Again, according to Toshiba. The 2.0 million hour MTTF is also supported for the new 6TB and 8TB MG08-D Series models.

The Toshiba MG08-D Series 4TB, 6TB and 8TB HDD models are expected to be generally available in the first quarter of 2021.
