Technology Highlights

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%.

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.
