TOKYO—Toshiba Corporation’s (TOKYO: 6502) Storage & Electronic Devices Solutions Company today announced the addition of an 8TB[1] SATA model to its MG05 series of 3.5-inch[2] form-factor, enterprise capacity class of hard disk drives (HDD). Shipments start from today.

Alongside the expansion of IoT (Internet of Things) and the spread of cloud services, the volume of data generated and accumulated continues to increase, and higher-capacity, higher-performance HDDs are constantly required in cloud data centers and their storage systems.

To meet these requirements, the new 8TB model offers an approximately 33% increase in maximum capacity from the 6TB of the prior MG04 series. It also delivers an approximately 12%[3] increase in sustained data rate to 230MiB/s and an approximately 42%[4] improvement in MTTF[5] to 2,000,000 hours. These improvements in capacity, speed and reliability can contribute to the reduction of TCO (Total Cost of Ownership) of the system.

The new HDDs support both industry-standard 4K native and 512emulation (512e) advanced format sector technologies, for use in the latest generation servers and storage systems, and are also suitable for legacy applications requiring 512 sector lengths using aligned-write environments.

The latest IDC market report[6] identified Toshiba as the fastest growing HDD vendor in 2016 over 2015, as measured by revenue and units. The same also found that Toshiba had a market share of 24% in the fourth quarter of 2016 as measured by units.

In February 2017, Toshiba’s cumulative production volume of near-line enterprise HDDs exceeded 10,000,000 units. Toshiba will continue to develop and offer products meeting customer demands.

Notes

[1] Definition of capacity: Toshiba defines a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.

[2] "3.5-inch" means the form factor of HDDs. They do not indicate the drive's physical size.

[3] Comparison between MG04 series: 205MiB/s and MG05 series: 230MiB/s

[4] Comparison between MG04 series: 1.4M hour and MG05 series: 2M hour

[5] MTTF (Mean Time to Failure) is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation. Actual operating life of the product may be different from the MTTF.
