Lower storage latency HDD suited for cloud-based workloads 

TOKYO— Toshiba Corporation's (TOKYO: 6502) Semiconductor & Storage Products Company today announced that it will launch the MC04ACA series, Toshiba's first enterprise capacity hard disk drive (HDD) optimized for servers supporting cloud-based applications and analytic workloads. With a 3.5-inch form factor, the MC04ACA series delivers up to 5TB[1] of storage with 7,200 rotations per minute (RPM) performance, reducing storage latency and making the MC04ACA series suitable for workloads and storage requirements generated by cloud computing. Mass production shipment in the Japanese market will start from the end of May.

The MC04ACA series is available in 2TB, 3TB, 4TB, and 5TB capacities and supports cloud use-case workloads of up to 180TB per year. The MC04ACA 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. The new series also boasts 6Gbit/s SATA interface speeds and Advanced Format sector technology, allowing compatibility with legacy applications and operating environments using aligned writes.

Outline of the New Products

[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.
