Ultrastar® 7K4000  
Delivering Industry-Leading  
Combining 7200 RPM  
Performance and Granular  
Power Control  
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 terabytes2 of 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  
HGST Quality and Service  
HGST’s Ultrastar 7K4000 extends the company’s long-  
standing tradition of performance and capacity leadership.  
The proven drive design enables high reliability and availability  
to customer data. Ultrastar quality, performance and world  
class technical support and service provides customers with a  
lower total cost of ownership over previous generations.  
Network Attached Storage (NAS)  
4TB, 3TB and 2TB | 7200 RPM  
SATA 6Gb/s and SAS 6Gb/s  
HGST drives are backed by an array of technical support  
and services, which may include customer and integration  
assistance. HGST is dedicated to providing a complete  
portfolio of HDD/SSD solutions to satisfy today’s  
monumental computing needs.
