Product Guides
The DeskstarTM 7K2000 hard drive delivers a colossal two terabytes of storage capacity and
7200 RPM performance in a standard 3.5-inch form factor. Now in its fourth-generation, the
7K2000 is based on a robust mechanical design that continues to set the industry standard for
quality and reliability. Through a patented ramp load/unload design, data heads are moved to
a ramp away from the disk where they rest during periods of inactivity. This greatly minimizes
the risk of shock damage by eliminating direct contact between the heads and disks,
reducing wear and heat while improving overall drive reliability and power efficiency. The
Deskstar 7K2000 also incorporates thermal fly-height control (TFC) technology which uses
an integrated heating element to precisely maintain a constant fly-height throughout read
and write operations to enhance overall data integrity, drive performance and reliability. The
7K2000 features industry-standard native 512-byte sector formatting, ensuring compatibility
with mainstream computing environments.
The Deskstar 7K2000 offers an exceptional blend of capacity and power efficiency, with idle
power savings over previous generation products up to 10%. On a watts per gigabyte basis,
idle power has improved over 120%. Leveraging eighth-generation power management
technology, including power-saving innovations like HiVERT™ technology, this drive delivers
best-in-class power management and thermal emissions to help manufacturers meet energy
compliance targets and extend drive life.
The Deskstar 7K2000 demonstrates Hitachi ecological leadership with its halogen-free
design and power-efficient operation. Both these features helped qualify the drive for the
Hitachi EcoTrac classification, which identifies products that minimize environmental impact
in the areas of product design, manufacturing, operation and disposal.
