Hitachi 2.5-inch 7200RPM 320GB HDD launched

Posted on Thursday, May 08 2008 @ 00:20 CEST by Thomas De Maesschalck
Hitachi is now shipping a 2.5" notebook HDD with a capacity of 320GB and a speed of 7200RPM. The firm says the new Travelstar 7K320 has 60% more capacity than its predecessor, while being 12% faster and consuming 22 percent less power.
The performance attributes of the Travelstar 7K320 allow consumers to opt for a full-featured notebook or compact desktop model, while still achieving all the capacity and performance typically associated with a more traditional desktop PC. The new drives bring forth a number of essential features that are in strong demand from manufacturers of notebooks, compact desktops, gaming systems, blade servers and video surveillance systems. Some of these attributes include best-in-class operating shock protection of 400Gs, 5,400 RPM-equivalent power consumption and quiet acoustics.

“As operating systems have grown more complex, users have struggled with an overall decrease in system performance,” said Larry Swezey, director, Consumer and Commercial HDD, Hitachi Global Storage Technologies. “Solid state drives (SSD) have yet to deliver an overall increase in speed, and certainly not at an affordable price. The 7,200 RPM speed of the Travelstar 7K320 provides an improved overall experience, at the capacities users want and at a far lower cost than SSD.”

Samsung still hasn't made publicly available it's 250 and here Hitachi shows them up with a 320...

Meanwile, Seagate is in the distant rear with 200, and Western Digital is in the dark ages with nothing over 5400 rpm.
