Industry's First Terabyte Hard Disk from Hitachi by March 2007

Hitachi company is planning to release 1 Terabyte Deskstar 7K 1000 by March 2007.

Capacity: up to 1 TB(1000 GB)
Rotational Speed: 7200 RPM
Interface standard: SATA 3.0Gb/s (Serial) and ATA Ultra 133 (Parallel)
Average seek time: 8.5 ms
Up to 32MB buffer on SATA models
Perpendicular magnetic recording technology
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

Hitachi's Perpendicular magnetic recording technology(PMR) and media technology improves noise characteristics and thermal stability. Deskstar 7K1000 features three advanced low power idle modes active, unload and low power. They reduce power consumption at the drive level up to 20%, optimize non operational latency and lower drive temperature for cooler system operation.

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.
