Hitachi Ultrastar™ drives offer proven reliability to protect data in mission critical applications, a stable design for fast and easy integration and Rotational Vibration Sensor (RVS) technology for great performance in multiple drive designs.

Raising the bar on performance and capacity for mission critical storage, Hitachi Global Storage Technologies’ Ultrastar 15K450 is the first enterprise hard drive to use perpendicular magnetic recording (PMR) technology to deliver 450GB of storage, currently the highest available capacity in 15,000 RPM enterprise-class hard drives.

The Ultrastar 15K450 is a performance leader, with Hitachi tests indicating a 30 percent improvement in sequential throughput over its predecessor. The drive features average seek times as low as 3.3 milliseconds and the fast rotational speeds reduce average latency time to 2 milliseconds, enabling customers to access data more quickly and efficiently.


Hitachi GST has added a new trio of hard drives to their enterprise product portfolio accompanying a comprehensive 5-year warranty.

Ultrastar 15K300 – Popular 15K 3.5-inch high-performance, enterprise-class hard drive for mission critical enterprise computing applications.

Ultrastar C10K147 – New 10K 2.5-inch hard drive optimized for power, performance and cost requirements of server applications (small form factor) and blade server environments.
