Toshiba Expands 2.5-inch HDD Line for Mobile PCs

By DE Editors

Toshiba Storage Device Division (SDD; Irvine, CA) announced a 200GB-per-platter 5,400rpm HDD, which the company says will provide the highest HDD capacity at 400GB for integration into mobile PCs. Plus, the company introduced a family of high-end 7,200rpm HDDs, offering up to 320GB storage capacity and improved performance.

The standard 9.5-millimeter-high package of both HDDs fits existing product designs, enabling an easier migration path to high-capacity storage for portable PC and personal storage manufacturers catering to the needs of mobile users.

In addition to increasing area density to 308 gigabits-per-square-inch, the 400GB MK4058GSX incorporates acoustic techniques that make the 5,400rpm HDD nearly inaudible during seek operations. The large storage capacity and silent operation of the MK4058GSX are suited for video and audio playback.

For optimum user experience in data-intensive applications such as image processing, video editing, and multimedia, Toshiba’s new 7,200rpm, MKxx54GSY series offers optimized firmware, caching algorithms, and fast data throughput of 1,020Mbps.

Both the MK4058GSX and MKxx54GSY series reflect Toshiba’s progress toward environmental soundness of its products by discontinuing use of certain chemical substances and reducing carbon dioxide emissions during HDD operation. The eco-conscious MK4058GSX and MKxx54GSY also deliver lower power consumption and cooler operation than 3.5-inch HDDs at the same capacity points, offering PC manufacturers a solution to miniaturize designs with more environmentally sound storage alternatives. Power consumption during read and write operation can be reduced by as much as 70 percent over the most power-conservative 3.5-inch HDDs with both of Toshiba’s new 2.5-inch HDDs.

These new HDDs will be shown at the Intel Developer’s Forum, August 19-21, in the Serial ATA International Organization booth.
