Hitachi Global Storage Technologies (Hitachi GST) has achieved yet another 1TB milestone by squeezing it on a single disk. The new one terabyte per platter (1TB/platter) Hitachi Deskstar 7K1000.D drive family is now shipping worldwide.
Featured in both Deskstar and CinemaStar brands, Hitachi is providing a full range of capacities, 250GB ? 1TB, on both low RPM CoolSpin and 7,200 RPM platforms.
For the ultra thin and light notebook market, Hitachi delivers the 7mm z-height Travelstar Z5K500 drives (636 gigabits per square inch "Gb/inē"). And now, designed for high-performing desktop computers and the consumer electronics (CE) market, Hitachi presents the new 1TB/platter Deskstar and CinemaStar family drives (569 Gb/inē).
"The areal density race continues and while having the highest capacity is appealing, reaching 1TB per platter is equally important as it serves a full range of applications and opportunities across the industry?s largest market volume," said Brendan Collins, vice president of product marketing at Hitachi GST. "As we ship our first 1TB per platter drives, we know we?re delivering capacity, reliability and value to a broad customer base. Not only are we shipping our 1TB per platter drives to our own Branded Business, but we are shipping to our channel partners as well, enabling them to design affordable HDD-based solutions at attractive price points."
The Hitachi Deskstar 7K1000.D hard drive family provides a combination of performance, capacity and reliability. Built using Hitachi?s 7,200 RPM platform, the drive features a 6Gb/second Serial ATA interface and a 32MB cache buffer. With eighth-generation power management technology and power-saving HiVERT innovations, this new drive provides up to 15 percent idle power savings over the previous model. Hitachi is also offering the new Deskstar 5K1000.B drive family with low power and cool operation. With CoolSpin technology, along with other Hitachi power management techniques, the Deskstar 5K1000.B delivers a 23 percent idle power savings over the Deskstar 7K1000.D.
Designed for storage-based TVs and DVRs, Hitachi?s new 1TB/platter CinemaStar 7K1000.D and 5K1000.B 3.5-inch product lines feature more than 10 technologies optimized for A/V streaming. All 1TB/platter 7,200 RPM and Coolspin versions ship with a 32MB cache buffer and a 6Gb/second Serial ATA interface.
The Hitachi Deskstar 7K1000.D and 5K1000.B CoolSpin versions are shipping today. CinemaStar drives are expected to ship in the Fall.
