Toshiba Announces 5TB, 7,200 RPM Enterprise HDD

The Storage Products Business Unit of Toshiba America Electronic Components, Inc., a committed technology leader, announces the MC Series, Toshiba’s first enterprise high-capacity hard disk drive (HDD) designed for bulk storage systems and servers supporting cloud-based applications and scale-out workloads. With a 3.5-inch form factor, the MC Series delivers up to 5TB1 of storage with 7,200 rotations per minute (RPM) performance, making the MC Series suitable for workloads and storage requirements generated by cloud computing.

The MC Series is available in 2TB, 3TB, 4TB, and 5TB capacities and supports the industry-standard cloud use-case workloads rating of up to 180TB per year – more than three times the industry-standard workload rating of desktop class HDDs. The MC Series supports 1TB per platter areal density, thus saving rack space and reducing the footprint and operational burden of cloud workload servers and storage systems. With up to 5TB storage capacity per host connection, the newest Toshiba HDD series boosts capacity per SATA port and enables fewer disks to handle the same storage capacity, reducing power and cooling costs on a per TB basis when compared to prior generation models with lower capacity per spindle. The new series also boasts 6Gbit/s SATA interface speeds2 and Advanced Format sector technology, allowing compatibility with legacy applications and operating environments using aligned writes.

“Our customers need efficient, high-capacity storage for their cloud-based servers and storage platforms,” said Don Jeanette, senior director of marketing at Toshiba Storage Products Business Unit. “With capacity points up to 5TB and 7,200 RPM performance, the Toshiba MC Series delivers the capabilities that today’s scale-out cloud architecture and use-cases require.”

Toshiba’s MC Series samples are available on a limited basis. For more information on Toshiba’s portfolio of industry-leading solid state drives, hard drives and hybrid storage solutions, visit To connect with Toshiba Storage, visit the corporate blog at and follow @ToshibaStorage on Twitter.

1 Definition of capacity: Toshiba defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and 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.”

DevOps is gaining traction in the federal government – and for good reasons. Heightened user expectations are pushing IT organizations to accelerate application development and support more innovation. At the same time, budgetary constraints require that agencies find ways to decrease the cost of developing, maintaining, and running applications.
