Advanced drive technology
The Hitachi Ultrastar 15K73 is the 3rd generation of 15,000 RPM enterprise-class hard drives from Hitachi. Leveraging award-winning technologies that have generated proven quality and high-performance, the Ultrastar 15K73 incorporates Fluid Dynamic Bearing motors (FDB) to contribute to increased capacity by enabling high-track density through a more precise position of the head. AFC
Media, also known as “pixie dust”, is an industry-first in 15,000 RPM enterprise-class hard drives, enabling higher areal densities by improving thermal stability, which in turn, maintains data integrity.
Designed for both high-performance and high-reliablity, the Ultrastar 15K73 was developed with powerful processors and read-write channels, advanced servo controls to improve seek and settle times, and overall improved mechanical stability to excel in today’s demanding data-processing environments.
Reliability features
Research and development teams throughout Hitachi Global Storage Technologies have a combined 80 years of award-winning hard drive development experience and technology that satisfy increasingly complex computing requirements. The Ultrastar 15K73 builds on this tradition. In order to ensure data-protection, the Ultrastar 15K73 incorporates advanced reporting tools such as Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) to signal potential drive problems.
Reliability is enhanced with load/unload technology and glass-substrate disks which provide a robust solution and high rotations speeds.
