Hitachi Delivers Power-efficient Enterprise Hard Drive


Hitachi Global Storage Technologies (Hitachi GST) today introduced its second-generation small form factor enterprise hard drive, the 10K RPM Ultrastar C10K300.

The new Hitachi drive is optimized for the power and performance requirements of rack-mounted servers and networked storage arrays.

The new drives are offered in 147GB and 300GB capacities and ship with a dual-port 6Gb/s Serial Attached SCSI (SAS) interface, which delivers 100 percent faster data throughput than its 3Gb/s predecessor.

The Ultrastar C10K300 is designed to provide higher server/storage density through compact 2.5-inch design, a low-power profile and improved thermal characteristics. The small form factor drive occupies 70 percent less physical space and consumes up to 65 percent less power than similar 3.5-inch enterprise drives.

The Ultrastar C10K300 is the company?s first enterprise-class drive to incorporate Advanced Power Management capabilities. The technology provides IT managers with multiple power mode options so that performance requirements can be achieved using the lowest possible energy expenditure. The Advanced Power Management implementation in the Ultrastar C10K300 delivers an idle power specification of 3.4 watts and 6.1 watts in active operating mode.

Fast response time is critical for a wide range of enterprise applications, including online transaction processing, real-time business analytics and timely delivery of data-intensive content-on-demand such as multiple channels of streaming video. The increased transfer rate of the new SAS interface operating at 6Gb/s is ideal for meeting these challenges. The new serial interface is also fully backward compatible with existing 3Gb/s devices.

The drives feature average seek times as low as 3.9 milliseconds and the fast rotational speeds reduce average latency time to 3 milliseconds.

The drive also includes a host of technologies designed to maximize reliability in mission-critical environments. Fluid Dynamic Bearing (FDB) motors deliver a low acoustic rating and improved data integrity, while Rotational Vibration Safeguard (RVS) technology anticipates and counteracts disturbances that can occur in multi-drive configurations. In addition, the Ultrastar C10K300 uses Hitachi-patented head load/unload ramp to minimize integration induced drive damage.

The Ultrastar C10K300 is now shipping to Hitachi's customers worldwide.
