Toshiba plans 2.5in 320GB laptop drive

Super high-capacity hard disk coming this year

Toshiba is working on the first 2.5in 320GB hard-disk laptops, and plans to release it by the end of the year.

The drive is one of a series of five that make up Toshiba's new MKxx52SX family of hard-disk drives, the company announced today. The 320GB model will contain two platters - the circular disks on which data is recorded. Other drives in the range will offer between 80GB and 250GB of storage space. They will connect via a 3Gbps (bits per second) serial ATA (SATA) interface.

The amount of data that can be stored on a hard-disk drive is constantly expanding as drive makers fine tune technology, and the needs of laptop users are growing in tandem with the expansion in drive space. While business users might not require such a capacious drive, users of multimedia laptops will almost certainly welcome the extra space to store video.

Today, some laptops feature digital TV tuners and companion video recording software, allowing them to double as a digital video recorder. Also, editing of home video is becoming increasingly popular, thanks to internet video websites such as YouTube.
