HDS721010KLA330 - HGST 1TB 7.2K 64MB SATA 6G 3.5

An industry fi rst, the Hitachi Deskstar 7K1000 hard disk drive delivers up to one terabyte ofstorage capacity for demanding consumer and commercial computing products. It leveragesthe industry’s most reliable perpendicular magnetic recording (PMR) techniques and the latestadvancements in silent acoustics, shock protection, and head technology to maximize capacity,performance and fi eld reliability. Best-in-class power management and thermal emissionshelp manufacturers meet energy compliance targets and extend drive life.Proven PMR technologyField-proven in 2.5-in. drives, Hitachi’s PMR implementation continues to demonstratereliability equal to or exceeding conventional longitudinal technology. The Deskstar 7K1000’ssecond-generation PMR head and media technology improves noise characteristics andthermal stability.Reduced power idle modesUnique to Hitachi drives, the Deskstar 7K1000 features three advanced low-power idlemodes—active, unload and low-power. Together, they reduce power consumption at the drivelevel up to 20%, optimize non-operational latency and lower drive temperature for coolersystem operation.Outstanding shock resistance and power effi ciencyThrough a patented ramp load/unload design disk heads (in non-operating modes) areunloaded to a ramp outside the disk where they rest in a low-power ‘unload idle’ state untilactivated. In low RPM drives, this can reduce power by up to 50%. Ramp load/ unloadprovides tangible benefi ts for the drive and host product. It greatly minimizes the risk of shockdamage by eliminating direct contact between the heads and disks. Reduced wear and heatimprove overall drive reliability. In the event of power loss to the drive, heads are unloadedusing energy extracted from the spinning disks. This patented power-saving feature helps toreduce overall maintenance costs and extends the drive service life.Another contributor to Deskstar 7K1000’s exceptional shock performance and power savingsis the use of compact, low-mass femto air-bearing sliders.Extended fi eld reliabilityAn integrated thermal sensor monitors operating temperature, enabling the host processor tointelligently adjust airfl ow as needed for cooling. Sensor integration reduces component costand increases reliability.Deskstar 7K1000’s thermal fl y-height control (TFC) uses an integrated heating element toprecisely maintain a constant fl y-height throughout read and write operations. This reducesraw 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 offersbetter performance and reliability in harsh conditions.Hitachi Design StudiosLocated around the world, Hitachi Design Studios assist customers with all aspects of integratinghard drives into consumer electronic devices.
