HGST Ultrastar® 7K4000 is the world’s first 4TB 7200 RPM hard drive with a 2.0 million

hours MTBF specification and backed by a full 5-year warranty. Ultrastar 7K4000 represents

the sixth-generation HGST 5-platter design, which has been field proven by top server and

storage OEMs and Internet giants. Engineered for the highest quality, the Ultrastar 7K4000

is put through grueling design tests during development and must pass stringent ongoing

reliability testing during manufacturing. Ultrastar 7K4000 delivers by reducing downtime,

eliminating service calls and minimizing TCO.

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. To meet these demands, Ultrastar 7K4000 delivers 33% more capacity in

the same footprint at 24% lower W/GB than its predecessor, Ultrastar 7K3000. Now you can

get 2.4PB in the footprint of a standard 19-inch enterprise storage rack by stacking ten 4U,

60-bay enclosures. Ultrastar 7K4000 dual port SAS is available in traditional 512, 520 and

528 byte sector size. Ultrastar 7K4000 SATA 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.

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 2W during standby/sleep modes,

freeing up precious headroom for growing enterprise needs.

The Ultrastar 7K4000, with its halogen-free design and power-efficient operation, qualifies

for the HGST EcoTrac classification, which identifies products that minimize environmental

impact in the areas of product design, manufacturing, operation and disposal.
