Hitachi Global Storage Technologies (HGST) has announced what it claims is the industry's highest-capacity 10,000rpm, enterprise-class hard drive: the Ultrastar C10K1200.

The 2.5-inch drive comes in capacities of up to 1.2TB and features a serial-SCSI (SAS) interface, a 64MB cache buffer and two million hour mean-time between failure (MTBF) rating. The Ultrastar C10K1200 uses less than 5W during idle mode.

HGST, now owned by Western Digital, said the Ultrastar C10K1200 is targeted at 24x7 enterprise applications such as data mining/analysis, business processing and delivery of data-intensive content-on-demand such as multiple channels of streaming video.

The 1.2TB Ultrastar C10K1200 drive delivers 33% more capacity in the same 2.5in form factor as HGST's previous 10,000rpm drives. By using the new model in a 2U (3.5in high) rack-mountable server with 24 drive bays, users can get up to 28.8TB of capacity.

Some Ultrastar C10K1200 models also offer data encryption for hardware level data security.
