Product Overview

The Seagate Advantage
System integrators need to custom fit storage
to their individual systems. The Seagate DB35.4
Series drive, which has already redefined value for
high-definition video systems, lets manufacturers
optimize drive performance for demanding DVR
and media center environments. The DB35.4
Series drive continues to raise the bar with cost-
effective, reliable storage compatibilities for video
and media applications.
The DB35.4 Series drive gives integrators special
features for tuning DVR operations:
•Performance optimization tunes the drive
for the sequential streaming needed for
uninterrupted digital media.
•Drive locking features enhance fair use
of digital programming by simplifying the
implementation of rock-solid drive security—
video content stays on the DVR.
•Low-power operation and spin-up allow the
manufacturer more leeway in selecting cost-
efficient power supplies. These tools also
help to keep DVR internal temperatures under
control for enhanced system reliability.
Seagate Design Service Centers provide design
and testing support that helps integrators
bring products to market faster, with enhanced
reliability and performance.

New Customer Requirements
The DB35.4 Series drive delivers the reliability,
capacity and performance needed by the
next generation of DVRs and media centers.
Entertainment consumers can easily archive entire
seasons of television programming on their DVRs,
while home media centers become a mainstay
of the home theater with enough capacity for
movies, photos, music and home video.
Seagate DB35.4 Series drives are Windows
Vista-certified, enabling integrators to build
reliable systems with quiet storage. These drives
are tuned for the optimal video performance, low
power consumption and content security required
by this next generation of applications.
Enabling New Opportunities
DVRs have reached critical mass, with an
expected worldwide install base of over 135
million households by 2010 (IMS Research,
2006). DVR-capable products have become a key
strategy for staying competitive for U.S.-based
satellite and cable companies, while more than
50 percent of households in EMEA are forecast
to have digital television service by 2009 (IMS
Research, 2007). The fast-growing Asia-Pacific
market leads the world in product diversity,
with emerging devices supporting IPTV video
delivery, as well as other Internet-connected
video appliances coming on the scene. Seagate
provides active storage solutions for any DVR,
media center or video storage device, enabling
our customers to keep up with growing demands
for entertainment content storage.
