Travelstar Z5K320 family (5400 RPM, 8MB cache)volume shipments will begin in July, while Travelstar Z7K320(720 RPM, 16MB cache) and the CinemaStar Z5K320(specifically designed for A/V streaming devices) drive families will begin in August.

“The relentless pursuit for thinner, lighter and lower cost notebook PCs is impacting the design requirements of all PC components, including hard disk drives,” said John Rydning, research director at IDC. “Hitachi’s plan to satisfy these design requirements with its new 7mm z-height, one-disk, mobile 2.5-inch hard disk drive, along with its strategy to make it price-competitive with standard 9.5mm products, should drive broad adoption.”
