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 2.4PB 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.

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 2W 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, minimizes environmental impact
in the areas of product design, manufacturing, operation
and disposal.
