Ultrastar 15K73 hard
disk drives
High-performance. Capacity. Technology.
Highlights:
- Rotational speeds of 15,000 RPMs and an average seek time as
low as 3.9ms to help boost performance
- Capacities of 73 GB or 36 GB provide configuration flexibility
- Incorporates technologies such as Fluid Dynamic Bearing
motors, (FDB), to help increase the reliability and robustness of
the drive
- First server-class 15,000 RPM drive to incorporate antiferromagnetically coupled
technology, (AFC), also known as “pixie-dust”. AFC enables higher areal densities by
improving thermal-stability, which maintains data-integrity
Advanced drive technology
The Hitachi Ultrastar 15K73 is the 3rd
generation of 15,000 RPM enterpriseclass
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 enterpriseclass
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
coupled technology, (AFC), also known
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.
write channels, advanced servo
Reliability is enhanced with load/unload
technology and glass-substrate disks
which provide a robust solution and high
rotations speeds.
Support for advanced applications
and interfaces
The Ultrastar 15K73 provides high-datathroughput
for data-intensive applications
with the Ultra 320 SCSI (backward compatible)
interface. Also available in a
2Gbits/s Fibre Channel interface to allow
for flexible, high-bandwidth data transfers.
