Hitachi Global Storage Technologies introduced the Ultrastar 15K147, a high-performance, highly reliable enterprise disk drive, designed to excel in mission-critical computing environments with booster performance thanks to new 15 000rpm spindle speed, which provides up to 33% more I/Os per second than current-generation 10 000rpm products.
The Ultrastar 15K147 is available in 36GB, 73GB and 147GB capacities with 2, 3 or 5 glass disk platters respectively and in Ultra 320 SCSI and 2Gb/s FCAL interfaces. The Ultrastar 15K147 delivers average seek times as low as 3.3ms and the 15 000rpm rotation speed reduces average latency time to 2ms, enabling customers to access data more quickly and efficiently and providing 1129Mb/s maximum internal transfer rate. The drives feature a large, 16MB 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) technology. RVS is used to protect drive performance in high rotational vibration environments, primarily in multi-drive configurations. Fluid dynamic bearing (FDB) motors deliver a low acoustic rating and improved data integrity.
The performance breakthrough achieved by Ultrastar 15K147 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, intensive database queries and other multi-user applications.
15K147 is currently shipping to customers worldwide.
