Combining 7200 RPM Performance And Granular Power Control
Operating at 7200 RPM, the HGST Ultrastar® A7K2000 offers better overall performance
than slower-RPM, capacity-oriented drives at impressively low power-consumption rates.
When compared to the previous generation Ultrastar A7K1000, the A7K2000 offers up to a
155% improvement in sustained data transfer rate. With five Advanced Power Management
modes, a 36% reduction in watts during low-RPM idle mode, and using less than 1W during
standby/sleep mode, the Ultrastar A7K2000 can help data centers achieve lower AC power
and HVAC requirements, freeing up precious headroom for growing enterprise needs.
Delivering Industry-Leading Reliability
With a robust fourth-generation mechanical design, Ultrastar A7K2000 is specifically built
and tested for the enterprise. The Ultrastar SATA drive family features HGST-patented
Rotational Vibration Safeguard (RVS) sensor technology, which optimizes drive reliability
in multi-drive RAID arrays and rack-mounted systems. Backed by a five-year warranty, the
Ultrastar platform has earned HGST a reputation among server and storage vendors as a
global partner dedicated to delivering the highest quality and reliability in the industry.
Innovation for a more sustainable environment
The Ultrastar A7K2000 demonstrates HGST ecological leadership with its halogen-free
design and power-efficient operation. Both these features serve to qualify the drive for the
HGST EcoTrac classification, which identifies products that minimize environmental impact
in the areas of product design, manufacturing, operation and disposal.

One MB is equal to on million bytes, one GB is equal to one billion
bytes and one TB equals 1,000GB (one trillion bytes) when referring
to hard drive capacity. Accessible capacity will vary from the stated
capacity due to formatting and partitioning of the hard drive, the
computer’s operating system, and other factors.
