Hitachi Introduces 400GB Hard Drive
Posted Mar 16, 2004

Hitachi Global Storage Technologies has announced the world's highest capacity 3.5-inch ATA hard drive, the 400GB Deskstar 7K400. The new drive has been designed for audio video (AV) and ATA nearline environments, where large capacities and a lower per-gigabyte cost are key requirements.

Hitachi has designed the Deskstar 7K400 to address the growing demand for high-capacity DVRs. The drive is the first to include a new AV feature, known as Streaming Command Set. The AV feature is designed to enhance streaming functionality in digital video applications. Streaming Command Set integration optimizes the drives for storing and retrieving digital video content on a DVR. Hard drives are key to enabling technology that will drive future growth of the DVR market.

Yankee Group, a Boston-based research and consulting firm, predicts that DVRs will be found in approximately 24.7 million homes by the year 2007. High definition television broadcasts are among the many factors that are driving the need for additional DVR storage capacity. 8.7GB of storage is required for each hour of broadcast HDTV recording. The Deskstar 7K400 provides enough capacity to store 400 hours of standard TV, 45 hours of HDTV, or more than 6,500 hours of digital music. In addition to its capacity, the Deskstar 7K400's 7,200 rpm performance is also well-suited to meet the rigorous demands of HDTV recording.

Several Deskstar 7K400 design attributes combine to protect customer data and increase capacity. Among these features are a new anti-rebound actuator latch and Rotational Vibration Safeguard technology (RVS). The RVS technology is used to ensure drive performance in high rotational vibration environments, where there are multiple drives in a single enclosure. The Deskstar 7K400 also features a spindle motor that is used in enterprise-class hard drives.

The Deskstar 7K400 has an 8MB-buffer and carries a three-year warranty. Hitachi is currently shipping Deskstar 7K400 drives in limited quantities.
