Toshiba today announced the MC Series, its 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 5TB of storage with 7,200 rotations per minute (RPM) performance.

The MC Series is available in 2TB, 3TB, 4TB, and 5TB capacities and supports the 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 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.

Toshiba says its new series samples are now available on a limited basis.
