Hitachi offers more media storage with 400G-byte drive

Hitachi Global Storage Technologies Inc. has launched a new 3.5-inch hard disk drive with a capacity of 400GB, higher than any other drive in this class, the company announced Wednesday. The drive 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 optimizes the drive for storing and retrieving digital video content. The new drives will ship with Parallel ATA and Serial ATA storage interfaces providing data transfer speed of 1.5 G bps (bits per second).

The drive consists of five disk platters with a rotational speed of 7,200 rpm (revolutions per minute) 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 over 6,500 hours of high quality digital music, Hitachi said.

Brother QL-820NWB Professional Label Printer

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

Brainstorming, innovation, problem solving, and negotiation have all become much more productive and valuable if people can easily collaborate in real time with minimal friction.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
