Hitachi Deskstar 7K1000 0A35375 / HDS721010KLA330 1000GB / 1TB 7.2K SATA Hard Drive - Refurbished OEM

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 advancements 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

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 benefi ts for the drive and host product. It greatly minimizes the risk of shock damage by eliminating direct contact between the heads and disks. Reduced wear and heat improve overall drive reliability. In the event of power loss to the drive, heads are unloaded using energy extracted from the spinning disks. This patented power-saving feature helps to reduce overall maintenance costs and extends the drive service life. Another contributor to Deskstar 7K1000’s exceptional shock performance and power savings is the use of compact, low-mass femto air-bearing sliders.

Extended field reliability

An integrated thermal sensor monitors operating temperature, enabling the host processor to intelligently adjust airfl ow as needed for cooling. Sensor integration reduces component cost and increases reliability. Deskstar 7K1000’s thermal fl y-height control (TFC) uses an integrated heating element to precisely maintain a constant fl y-height throughout read and write operations. This reduces raw soft error rate and, in turn, improves overall data integrity, drive performance and reliability. Deskstar 7K1000’s iridium-manganese-chromium (IrMnCr) read head sensor technology offers better performance and reliability in harsh conditions.

Condition Levels Explained

The product has been built, rebuilt or repaired at the original manufacturer's factory (Note we NEVER sell 3rd party repaired items, as we do not find them to be reliable enough). Often these products are extremely close to new in condition, except that they contain at least one recycled or repaired component. Failure rates are often lower on these devices since they have been far more thoroughly tested than new items.
