HiVERT™ technology
The first introduction of Hitachi Voltage
Efficiency Regulator (HiVERT) technology was
on a 2.5 inch product now Hitachi uses this
technology to achieve best-in-class power
efficiency on 3.5 inch products. In fact the
DeskstarP7K500 achieves power savings
of up to 40% over previous-generation
products. This reduction was accomplished
by using the same system-on-chip (SoC) that
is used in Hitachi’s Travelstar 2.5-inch mobile
product line, where low power has long been
a key design attribute to maximize battery
life in notebook PCs.
This SoC incorporates HiVERT technology
in which switching regulators are used
in place of less power-efficient linear
regulators in the voltage reduction
processes.
IrMnCr read sensor
To address the demand for increased
capacity and highly reliable operation of the
read sensor, Hitachi scientists developed a
material and process for the manufacture of
ultra-small read sensors. Use of a new read-
head alloy – iridium-manganese-chromium
(IrMnCr), incorporating an extremely thin
layer of ruthenium in the structure to create
a very high “pinning field”, resulted in the
storage industry’s most stable and reliable
read-sensor technology.
CoolSpin Technology
The CinemaStar 5K500, Hitachi’s first
CoolSpin drive, uses an enhanced motor
design to limit peak current during spin-up
and enable lower continuous running power.
With CoolSpin, Hitachi was able to achieve
just the right blend of performance, power
management and acoustics for digital video
applications. CoolSpin drives allow system
builders to develop set-top boxes and DVRs
that run cooler and require less power,
ultimately leading to improved product
reliability and lifespan.
Enhanced Adaptive Battery Life Extender
(ABLE)
Hitachi understands the challenges its
customers face in maximizing battery life
in their products, and engineered the ABLE
power management technology in response.
ABLE enables the host system to realize the
optimum power utilization from the drive,
and customize power consumption at drive
level to suit the specific application.
Hitachi load/unload technology
Load/unload technology helps keep the
read/write heads from coming into contact
with the media - even when the drive is not
rotating.
Some of the many benefits include increased
robustness, reliability and reduced power
consumption. Hitachi is the only company
to use load/unload technology across its
complete product line.
Bulk Data Encryption
Several Hitachi hard drives now offer
optional Bulk Data Encryption – a hard-
drive-level data security mechanism that
puts users’ data effectively ‘under lock
and key’, offering virtually impenetrable
protection. As an alternative to protecting
data through software-based encryption
or system-level passwords, hard-drive level
encryption provides better performance and
a much higher level of security.
Rotational Vibration Safeguard (RVS)
Enterprise class Hitachi hard drives have
advanced Rotational Vibration Safeguard
(RVS) that actually anticipates disturbances
and counteracts them— maximizing
performance in the most arduous conditions.
Vibration sensors at the edges of the disk
feed forward to the actuator, warning it of
oncoming disruption. In benchmark tests,
this technology improves performance in
business and high-end systems by as much
as 300%.
