. Ultrastar 7K4000 represents the sixth-generation HGST 5-platter design which has been field proven by top server & storage OEMs & Internet giants. Engineered for the highest quality the Ultrastar 7K4000 is put through grueling design tests during development & must pass stringent ongoing reliability testing during manufacturing. Ultrastar 7K4000 delivers by reducing downtime eliminating service calls & minimizing TCO.. Operating at 7200 RPM Ultrastar 7K4000 offers better overall performance than slower RPM capacity-oriented drives & does so at impressively low power-consumption rates. The Ultrastar 7K4000 can help data centers achieve lower AC power & HVAC requirements. With five advanced power Management modes the 7K4000 achieves a 59% reduction in watts during low RPM idle mode & uses less than 1 W during standby/sleep modes freeing up precious headroom for growing enterprise needs Key Product Info. 2.0 million hours MTBFAdvanced format 512 byte emulation (512e)6 Gb/s SATA interface Dual Stage Actuator (DSA) & Enhanced Rotational Vibration Safeguard (RVS) for robust performance in multi-drive environments Product Features Delivering industry-leading quality & reliability Ultrastar 7K4000 represents the sixth-generation HGST 5-platter design which has been field proven by top server & storage OEMs & Internet giants. Engineered for the highest quality the Ultrastar 7K4000 is put through grueling design tests during development & must pass stringent ongoing reliability testing during manufacturing. Ultrastar 7K4000 delivers by reducing downtime eliminating service calls & minimizing TCO. Increasing capacity density by one third To deal with the explosive petabyte (PB) growth data centers require large amounts of efficient storage. Reducing W/GB without expanding floor space is vital to lowering operating costs. Now you can get 2.4 PB in the footprint of a standard 19-inch enterprise storage rack by stacking ten 4U 60-bay enclosures. Ultrastar 7K4000 is an advanced format drive using 4096-byte sector size to provide enormous capacity earlier than otherwise possible for environments optimized for this technology. Advanced format drives are backwards compatible with legacy 512-byte sector size by offering built-in 512-byte emulation through the SATA interface. Combining 7200 RPM performance & granular power control Operating at 7200 RPM Ultrastar 7K4000 offers better overall performance than slower RPM capacity-oriented drives & does so at impressively low power-consumption rates. The Ultrastar 7K4000 can help data centers achieve lower AC power & HVAC requirements. With five advanced power Management modes the 7K4000 achieves a 59% reduction in watts during low RPM idle mode & uses less than 1 W during standby/sleep modes freeing up precious headroom for growing enterprise needs. Innovating for a more sustainable environment The Ultrastar 7K4000 with its halogen-free design & power-efficient operation qualifies for the HGST Eco Trac classification which identifies products that minimize environmental impact in the areas of product design manufacturing operation & disposal.
