Deskstar 7K1000 – What Makes it so Special ?

Quality & Reliability• Shipping in volume since March 2007 with superb reliability record

• Incorporates key enabling technologies such as Thermal Fly Height Control, Head Load / Unload, and Iridium Manganese Chromium (IrMnCr) read head sensors

Performance• Leverages the industry’s most reliable perpendicular recording technology

• Superb and consistent performance make it the drive of choice for key OEMs and Integrators worldwide

• Glowing press reviews reflect it’s top class performance which beats all rivals

Environmental• Latest advancements in silent acoustics, shock protection and head technology

• Best in class power management and thermal emissions


Thermal Fly Height Control – How it Works

Maintains consistent spacing between the read/write heads and the recording disk• Improves overall data integrity, drive performance and reliability

Nominal read/write element protrusion before TFC adjustment

Read/write element protrusion with TFC adjustment


Head Load / Unload – Rugged & Power Efficient

Ramp protects read / write heads and media• Mature technology that has been used on all Deskstar drives since 1999• Reduces start / stop wear for longer drive life• Outstanding shock resistance & power efficiency


Hitachi Breakthrough – IrMnCr Read Head Sensors

IrMnCR has enabled a 2X improvement in precision & sensitivity of the read process

New alloy combination & process• Iridium-manganese-chromium (IrMnCr)

• Dusting of Ruthenium

• Super hot, ultra-high magnetic field oven

Increases hard drive’s ability to read data reliably in extreme conditions• Temperature variance – hot or cold

• Humidity

• Shock

Result: The most reliable hard drive read-sensor technology

Ultrastar A7K1000 – True Server Pedigree

Specifically designed for servers and multi-drive arrays• Mature, tried and tested design with proven field reliability

• Five platter design ensures that we deliver leading edge quality and reliability, not just leading edge capacity – this is very much a traditional server approach

Rotational Vibration Safeguard (RVS) technology • Dramatically reduces the effects of vibration which is always present in multi-drive

arrays

• Optimizes performance and reliability

Designed to outperform and outlast the competition• Benchmark winner

• Top choice for server and controller vendors when they display their products at trade shows

• Tested 1.2 million hours MTBF specification

• Five year warranty


Rotational vibration is a particular characteristic of multi-drive arrays• Can cause a standard hard drive to seriously under-perform as the heads have difficulty tracking

accurately and can even lead to the RAID controller reporting the drive as faulty.

Hitachi’s RVS technology ensures the Ultrastar A7K1000 keeps on performing• G-sensors on the drive monitor any external vibrations and forward a signal to the actuator that

controls the head’s position. The actuator then compensates for the disturbance. In this way, the head is able to ‘ride’ the vibration and stay on track.

Proven Field Reliability – Way Ahead of Competitors

Quality & reliability – the proof is in the history• The Deskstar 7K1000 and Ultrastar A7K1000 are evolutionary designs based on the

Deskstar 7K500 and Deskstar E7K500• No other competitor’s drive can boast such a superb reliability track record
