Highlights

Quality and Reliability

• 2.0 million hours MTBF¹

HGST Ultrastar® 7K4000 is the world’s ꢀirst 4TB 7200 RPM

hard drive with a 2.0 million hours MTBF speciꢀication

and backed by a full 5-year warranty. Ultrastar 7K4000

represents the sixth-generation HGST 5-platter design,

which has been ꢀield 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.

• Up to 4 terabytes²of capacity

• SATA 6Gb/s and SAS 6Gb/s models for conꢀiguration

ꢀlexibility

• Advanced Format* SATA with 512-byte

emulation (512e)*

• Dual Stage Actuator (DSA) and Enhanced Rotational

Vibration Safeguard (RVS) for robust performance in

multi-drive environments

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 ꢀive

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.

• 24x7 accessibility for enterprise-class, capacity-

optimized applications

• 5-year limited warranty

Innovating for a More

Increasing Capacity Density by

One Third

Sustainable Environment

The Ultrastar 7K4000, with its halogen-free design and

power-eꢁicient operation, minimizes environmental impact

in the areas of product design, manufacturing, operation

and disposal.

To deal with the explosive petabyte (PB) growth, data centers

require large amounts of eꢁicient storage. Reducing W/GB

without expanding ꢀloor 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.

Applications/Environments

• Cloud storage

• Massive Scale Out (MSO)

• Data warehousing & mining

• Disk-to-disk backup & archiving

• RAID arrays

bytes and one TB equals 1,000GB (one trillion bytes) when referring

to hard drive capacity. Accessible capacity will vary from the stated

capacity due to formatting and partitioning of the hard drive, the

computer’s operating system, and other factors.

²MTBF and AFR targets are based on a sample population and are

estimated by statistical measurements and acceleration algorithms

under median operating conditions. MTBF and AFR ratings do not

predict an individual drive’s reliability and do not constitute a warranty.
