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.

1 Intended for use in lower duty cycle environments in the enterprise storage hierarchy such as nearline applications. This MTBF rating is based

on a sample population and is estimated by statistical measurements and acceleration algorithms under nominal operating conditions. MTBF

ratings are not intended to predict an individual drive’s reliability. MTBF does not constitute a warranty.

2 One MB is equal to one million bytes, one GB is equal to one billion 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.

How to read the Ultrastar model number

HUS724040ALE640 = 4TB, SATA 6Gb/s,

64MB buffer


U = Ultrastar

S = Standard

72 = 7200 RPM

40 = Full capacity — 4TB

40 = Capacity this model, 40 = 4TB

(30 = 3TB , 20 = 2TB)

A = Generation code

L = 26.1mm z-height

E6 = SATA 6Gb/s, 512e

4 = 64MB buffer

0 = No encryption (1 = encryption)
