HGST Ultrastar 7K4000 is a 4TB 7200 RPM hard drive with a 2.0million hours MTBF specification and backed by a full 5-yearwarranty. Ultrastar 7K4000 represents the sixth-generation HGST5-platter design, which has been field proven by top server andstorage OEMs and Internet giants. Engineered for the highestquality, the Ultrastar 7K4000 is put through grueling design testsduring development and must pass stringent ongoing reliabilitytesting during manufacturing. Ultrastar 7K4000 delivers by reducingdowntime, eliminating service calls and minimizing TCO.

Operating at 7200 RPM, Ultrastar 7K4000 offers better overallperformance than slower RPM capacity-oriented drives, and does soat impressively low power-consumption rates. The Ultrastar 7K4000can help data centers achieve lower AC power and HVAC requirements. With five Advanced Power Management modes, the 7K4000 achieves a59% reduction in watts during low RPM idle mode, and uses less than1W during standby/sleep modes, freeing up precious headroom forgrowing enterprise needs.
