San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- 15,000 RPM Ultrastar Drive Designed to Address the Performance and Reliability Requirements of the Most Demanding Server Environments
Hitachi Global Storage Technologies Hitachi Global Storage Technologies is a wholly owned subsidiary of Hitachi, Ltd. Summary
Hitachi purchased IBM's hard disk drive division, integrated their own HDD operations, and launched the company in 2003. today introduced the Ultrastar 15K147, a high-performance, highly-reliable enterprise disk drive, designed to excel in mission-critical computing environments. The 15,000 RPM drive is Hitachi's highest-performer, delivering as much as 33 percent more I/Os per second than current-generation 10,000 RPM products. This performance breakthrough enables customers to address their throughput requirements using fewer drives, reducing total cost of ownership. The price performance characteristics of the new Ultrastar drive make it an ideal solution for online transaction processing See transaction processing and OLCP. , intensive database queries and other multi-user applications.
The Ultrastar 15K147 delivers average seek times as low as 3.3 ms and the 15,000 RPM rotation speed reduces average latency time to 2 ms, enabling customers to access data more quickly and efficiently. The drives feature a large, 16 MB cache that minimizes command overhead and improves average read/write response time.
The Ultrastar 15K147 is built on a mature design platform to ensure greater reliability and reduced qualification times. Several Ultrastar 15K147 design attributes combine to protect customer data, including Rotational Vibration Safeguard (RVS RVS Reverse

Hitachi also offers the only enterprise-class hard drive utilizing a head load/unload ramp A small ramp in a disk drive that the read/write head moves to when the drive is turned off. Located off the edge of the platters or in the middle, these ramps were first used with laptop drives to withstand shock and later migrated to desktop drives. , which minimizes integration induced drive damage.
"The Ultrastar 15K147 is designed to meet the needs of IT managers that are focused on lowering their storage total cost of ownership by using disk drives with the highest available reliability and I/Os per second," said Manjeshwar Bhat, general manager, Enterprise HDD (Hard Disk Drive) See hard disk and HDD caddy.

and mission-critical reliability is what 15K RPM is all about. These new Ultrastar drives are perfectly suited to meet the needs of today's most demanding data processing data processing or information processing, operations (e.g., handling, merging, sorting, and computing) performed upon data in accordance with strictly defined procedures, such as recording and summarizing the financial transactions of a applications."
