Operating at 7200 RPM, Ultrastar 7K4000 offers better overall performance than slower RPM capacity-oriented drives, and does so at impressively low power-consumption rates. The Ultrastar 7K4000 can help data centers achieve lower AC power and HVAC requirements. With five advanced power Management modes, the 7K4000 achieves a 59% reduction in watts during low RPM idle mode, and uses less than 1 W during standby/sleep modes, freeing up precious headroom for growing enterprise needs.
