Hitachi today 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. A new industry-standard AV feature set makes the
drive well-suited for use in high-end digital video recorders (DVRs) that are
designed to record substantial amounts of high-quality digital programming.

The new drives will ship with Parallel ATA and Serial ATA (SATA) interfaces.
Several Deskstar 7K400 design attributes combine to protect customer data and
increase capacity, while maintaining Hitachi’s award-winning performance. 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 is backed by
Hitachi’s renowned compatibility testing labs and worldwide distribution
support. The drive has an 8MB-buffer and carries a three-year warranty.

Hitachi Global Storage Technologies today 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. A new
industry-standard AV feature set makes the drive well-suited for use in high-end
digital video recorders (DVRs) that are designed to record substantial amounts
of high-quality digital programming.

“Extremely high capacity disk drives are more essential now than ever with
digital video recording coming into the mainstream,” said Jose Antelo, general
manager, 3.5-inch Consumer and Commercial HDDs, Hitachi Global Storage
Technologies. “We are now in a position to extend our consumer electronics
portfolio to include the high-end device segments, most notably the nascent
market for high-capacity DVRs.”

Audio/Video Applications

Hitachi has designed the Deskstar 7K400 to address the growing demand for
high-capacity DVRs. The drive is the first to include a new industry-standard 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 (HDTV) 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. In addition to its
substantial capacity, the Deskstar 7K400’s 7,200 rpm performance is also
well-suited to meet the rigorous demands of HDTV recording.

The Deskstar 7K400 provides enough capacity to store the following:

400 hours of standard TV programming
45 hours of HDTV programming
More than 6,500 hours of high quality digital music
ATA Nearline Applications

The Deskstar 7K400 is ideally suited for nearline storage and other low I/O
applications. The drives provide superior capacity, data access times and
transfer rates at a comparable cost to that of tape or optical solutions. The
new drives will ship with Parallel ATA and Serial ATA (SATA) interfaces.

SATA is a scalable interface technology that currently delivers a maximum data
transfer rate of up to 1.5 Gb/s. SATA also simplifies device configuration,
improves data integrity and offers “hot-plug” capability, which allows the
drives to be installed or removed while the host system is operational. SATA
drives also use a compact cabling structure and smaller connectors that are
designed to enhance air flow and reduce system complexity.
