Ultimate performance meets high capacity

Hitachi’s next-generation 3.5-inch 15,000 RPM enterprise class hard drive delivers the performance and reliability required in mission-critical non-stop computing environments. Built upon the mature system architecture and electronics of the prior generation, the Ultrastar™ 15K450 provides a spacious 450GB capacity, 16MB cache and a choice of Serial Attached SCSI (SAS) 3Gb/s or Fibre Channel Arbitrated Loop (FCAL) 4Gb/s interfaces. These features make the Ultrastar 15K450 the ideal solution for demanding enterprise computing environments like online transaction processing, intensive data analysis and multi-user applications. The mature design of Ultrastar 15K450 helps ensure shorter qualification time.

Highest reliability for demanding environments

Important reliability features come standard in the Ultrastar 15K450. Rotational Vibration Safeguard (RVS) technology ensures drive performance in multi-drive systems where rotational vibration is likely to occur. Hitachi-patented Thermal Fly-height Control (TFC) technology maintains a consistent fly-height during the read/write process ensuring a better soft error rate, while end-to-end data protection enhances error detection for optimal data integrity. Finally, Hitachi offers the only enterprise-class hard drive utilizing a head load/unload ramp to help minimize drive failures as a result of handling during integration.

Proven PMR technology

The Ultrastar 15K450 is the first enterprise-class drive from Hitachi to use Perpendicular Magnetic Recording (PMR) technology. PMR has already been in use across the company’s mobile and desktop product lines and has been proven ready for the demanding mission-critical server and storage applications in the enterprise environment.

Compatibility

All SAS compatible servers including:
Dell PowerEdge 1900, 1950, 2900, 2950, 6900, 6950. PowerVault MD1000 and MD3000.
