Hitachi Deskstar 7K1000 Terabyte Hard Drive
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.
Perpendicualr Magnetic Recording (PMR)
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.
Serial ATA Topology
The DeskStar line is available with a 3GB/s interface to achieve the highest data throughput required for performance computing requirements.
RAMP Load Dynamics
Hitachi's patented ramp load/unload design increases shock protection and power savings by moving the heads away from the disk when it's not in use.
Thermal Fly-Height Control (TFC)
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.
Low Power 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.
