Ultimate performance meets high capacity
Hitachi’s next-generation 3.5-inch 15,000 RPM enterprise class hard drive delivers the perfor-
mance 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.
