HITACHI GLOBAL STORAGE WD HDS721010KLA330 Deskstar 7K1000 HDS721010KLA330 - Hard drive - 1 TB - internal - 3.5in - SATA 3Gb/s - 7200 rpm - buffer: 32 MB

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. Extended field reliability. An integrated thermal sensor monitors operating temperature, enabling the host processor to intelligently adjust airflow as needed for cooling. Sensor integration reduces component cost and increases reliability. Deskstar 7K1000s thermal fly-height control (TFC) uses an integrated heating element to precisely maintain a constant fly-height throughout read and write operations. Proven PMR technology. Field-proven in 2.5-inch drives, Hitachis PMR implementation continues to demonstrate reliability equal to or exceeding conventional longitudinal technology. The Deskstar 7K1000s second-generation PMR head and media technology improves noise characteristics and thermal stability. Outstanding shock resistance and power efficiency. Through a patented ramp load/unload design disk heads 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 benefits for the drive and host product. It greatly minimizes the risk of shock damage by eliminating direct contact between the heads and disks.
