Hitachi Terabyte Hard Drives
Hitachi is focused on maximizing the value of the hard drive by spearheading the era of the "smart" hard drive. Customized features have been incorporated into Hitachi's hard drives, tailoring them for the application-set that they serve. To that end, Hitachi's 1TB hard drives are targeted to two distinct application areas.
Deskstar 7K1000 - gaming and high-performance PCs, external storage devices and upgrade applications
SATA 3.0Gb/s and PATA-133 interfaces
Ramp load design for increased shock protection
Three low-power idle modes to boost power efficiency
CinemaStar 7K1000 - DVR applications
Adaptive error recovery and SMART command transport for optimized video streaming and picture quality
Smooth Stream Technology to optimize the drive for audio/video applications requiring reliable storage
"Bedroom quiet" acoustics
Finally, an enterprise version of the TB drive designed for lower duty-cycle, high-capacity enterprise environments is currently under evaluation at major OEM customers and is expected to be available in the second quarter.
The Deskstar 7K1000 SATA version will be available in Q1 2007 at 750-GB and one-TB capacities. The 1TB capacity point will have a suggested retail price of $399 (USD). The CinemaStar 1TB hard drive will be available in the second quarter.
