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 fi eld 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.
