Hitachi Global Storage Technologies has launched a 3.5-inch hard disc drive with a capacity of 400Gbytes, which has been designed for audio/video applications, and particularly with digital video recorders in mind.
The Deskstar 7K400 includes a technology called Streaming Command Set which optimises the drive for storing and retrieving digital video content. The drives will ship with Parallel ATA and Serial ATA storage interfaces providing data transfer speed of 1.5 bits per second.
The drive consists of five disc platters with a rotational speed of 7,200 rpm and an average seek time to retrieve a piece of data of 8.5 milliseconds.
The new higher capacity enables users to store 400 hours of standard TV programming, 45 hours of high-definition TV programming, or more than 6,500 hours of high-quality digital music, Hitachi said.
