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 exclusive Rotational Vibration Safeguard (RVS) sensor technology, which optimizes drive reliability in multi-drive RAID arrays and rack-mounted systems.

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.
