Extended field reliability
An integrated thermal sensor monitors oper-
ating temperature, enabling the host proces-
sor to intelligently adjust airflow as needed
for cooling. Sensor integration reduces
component cost and increases reliability.

Deskstar 7K1000’s thermal fly-height control
(TFC) uses an integrated heating element
to precisely maintain a constant fly-height
throughout read and write operations. This
reduces raw soft error rate and, in turn,
improves overall data integrity, drive perfor-
mance and reliability.

An industry first, the Hitachi Deskstar
®
7K1000 hard disk drive delivers up to one
terabyte of storage capacity for demanding
consumer and commercial computing
products. It leverages the industry’s most
reliable perpendicular magnetic recording
(PMR) techniques and the latest advance-
ments in silent acoustics, shock protection,
and head technology to maximize capacity,
performance and field reliability. Best-in-class
power management and thermal emissions
help manufacturers meet energy compliance
targets and extend drive life.

Proven PMR technology
Field-proven in 2.5-in. drives, Hitachi’s PMR
implementation continues to demonstrate
reliability equal to or exceeding conventional
longitudinal technology. The Deskstar 7K1000’s
second-generation PMR head and media
technology improves noise characteristics
and thermal stability.

Reduced power idle modes
Unique to Hitachi drives, the Deskstar 7K1000
features three advanced low-power idle modes
– active, unload and low-power. Together, they
reduce power consumption at the drive level
up to 20%, optimize non-operational latency
and lower drive temperature for cooler system
operation.

Outstanding shock resistance and
power efficiency
power efficiency
Through a patented ramp load/unload design
disk heads (in non-operating modes) are
unloaded to a ramp outside the disk where
they rest in a low-power ‘unload idle’ state
until activated. In low RPM drives, this can
reduce power by up to 50%. Ramp load/
unload provides tangible benefits for the drive
and host product. It greatly minimizes the risk
