Hitachi Global Storage Technologies (HGST) will ship new 2.5-inch hard drives with capacities up to 100GB for notebooks by the end of 2004, the company said today.

The Travelstar 5K100 and E5K100 hard drives spin at 5,400 rpm (revolutions per minute) and are available in 40GB, 60GB, 80GB and 100GB capacities. They are 9.5 millimetres in height, and consume relatively little power, the company said.

Both the 5K100 and E5K100 offer parallel ATA and serial ATA (SATA) support, the company said. All the models will be shipping to customers in the fourth quarter of this year. In the US, the 5K100 will be on sale at a suggested price of $126 for the 40GB, $170 for the 60GB version, $222 for the 80GB version and $263 for the 100GB version, Tadashi Hisanaga, a spokesman for Hitachi, said. Hisanaga declined comment on customers for the products.

HGST is aiming more of its small-diameter hard disc production at consumer electronics applications and believes that increasing numbers of consumers who are considering buying notebook computers want to have more than the 40GB of storage.The company believes the consumer electronics portion of the market was about 10 per cent in 2004. The company expects this share to grow to about 15 per cent in 2003 and to grow to about half the entire hard-disk market in 2007.

In May, HGST said it was doubling to 60 million units the annual production of its 1-inch Microdrive, 2.5-inch Travelstar and 3.5-inch Deskstar product lines and was investing $200 million to upgrade its factory in Thailand, where these drives are made.
