Highest capacity and reliability with a proven design

The Deskstar TM 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.

Outstanding energy eficiency

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.

Innovation for a more sustainable environment

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.
