Toshiba released today the first dual-platter 240GB (MK2431GAH) and single-platter 120GB (MKxx31GAL series) 1.8-inch HDDs forintegration into portable media players, camcorders and compact ultra-mobile PCs. Toshiba's two new Parallel ATA HDD families feature a high areal density at 344 gigabits-per-square-inch, using fourth-generation perpendicular magnetic recording (PMR) technology, which was first introduced and commercialized by Toshiba in 2005.

The new 1.8-inch HDD series uses a new mechanical and firmware design for enhanced durability, making the 80GB and 120GB single-platter HDDs well-suited for slim-line mobile gadgets and PC applications. The new dual-platter 240GB MK2431GAH product is especially suitable for light-weight mobile PC applications and high-end digital video camcorders, which require high capacity and ruggedness.

Design elements incorporated in the 240GB MK2431GAH optimize power performance to new levels with a 33 percent overall improvement in energy consumption efficiency over Toshiba's previous generation two-platter, 160GB 3,600 RPM 1.8-inch model. In addition, Toshiba's entire line of new 4,200 RPM 1.8-inch HDDs faeture new electrical components to reduce power consumption during read and write operations by 20 percent. In addition, PC applications benefit from the performance boost of an 8MB buffer.

The MKxx31GAL series has been designed to lower carbon dioxide emissions by 54 grams per year.

The new HDDs will be incorporated into CE and mobile PC products shipping this holiday season.
