HGST, formerly known as the Hitachi Global Storage Technologies unit it was bought by Western Digital, has announced the industry's highest-capacity 10,0000 RPM enterprise-class hard drive, the Ultrastar C10K1200.

The new Ultrastar C10K1200 provides an impressive capacity extension to HGST's proven Ultrastar C10K900 model and this 2.5-inch features SAS 6Gb/s interface and impressive 64MB cache buffer. Its fast 10K rotational speed, combined with all features and drive's low power, results in higher density servers, blades and network storage arrays.

With 1.2TB of capacity, the new Ultrastar C10K1200 also comes with Fluid Dynamic Bearing motor for low acoustic rating and improved data integrity as well as the Rotational Vibration Safeguard that anticipates and counteracts disturbances that can occur in multi-drive configurations and the HGST's patented head load/unload ramp to minimize integration induced drive damage. It also comes with Bulk Data Encryption for security.

According to HGST, the new 2.5-inch Ultrastar C10K1200 HDD is shipping today and has already been qualified by select OEMs.
