Ultrastar A7K2000, 1TB SATA II HDD, 8.89 cm (3.5 ") , 7200RPM, 32MB Cache, 680g, 20pk
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. Operating at 7200 RPM, it offers better overall performance than slower-RPM, capacity-oriented drives at impressively low power-consumption rates. The Ultrastar A7K2000 also features Hitachi-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 Hitachi 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.
