[. . . ] DeskstarTM 7K1000 3. 5-INCH HARD DISK DRIVES Industry's first terabyte hard disk drive for consumer and commercial computing applications Highlights > > > > > > > > Storage capacities up to 1TB Perpendicular magnetic recording technology SATA 3. 0Gb/s interface Ramp load design increases shock protection and power savings Thermal monitoring and fly height control enhance reliability Three low-power idle modes boost power efficiency Silent seek acoustics achieve ultra-quiet operation Host/drive authentication for hardware security 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. [. . . ] 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 1TB, 750GB | 7200 RPM Serial ATA 3. 0Gb/s 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 7K1000's thermal fly-height control (TFC) uses an integrated heating element to precisely maintain a constant fly-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.
