Delivering industry-leading quality and reliability
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.
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. 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 2.4
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 and granular power control
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 1W 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 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.
