The 2TB Ultrastar A7K2000 SATA 3Gb/s 3.5" Enterprise Hard Drive provides twice the data storage capacity of the prior generation Ultrastar A7K1000 drive, and does so using fewer watts. It is now possible to achieve a colossal 1.2 petabytes (PB) in the footprint of a standard 19-inch enterprise storage rack by deploying the 2TB A7K2000 in a stack of ten 4U, 60-bay enclosures. 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 percent improvement in sustained data transfer rate, and a 120 percent improvement in watts-per-GB. With five Advanced Power Management modes, a 36 percent 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.
