Fujitsu has developed a hard-disk drive suitable for use in laptops and video recorders with a capacity of 300GB. It is has the largest capacity in its class, the company claims.

The 2.5-inch drive features a serial ATA interface and offers a 50 per cent jump in capacity over Fujitsu's current most capacious hard-disk drive of this type, it said.

Higher capacity drives are available but they are typically larger and have slower interfaces. In the case of laptops the slower interface means they aren't as fast at handling the digital video files that are now common these days while for video recorders the larger size drives lead to bulkier products.

Fujitsu said the new drive will be available from late February. The company hopes to sell 1.5 million of the drives during fiscal 2007, which is the period from April to March 2008.
