 in a standard  
3.5-inch form factor
HelioSeal™ process and 7Stac™ design are 
keys to hermetically sealed drive with higher 
capacity   
TCOptimized™ design delivers on key 
elements of data center TCO:  capacity, 
power, cooling and storage density 
SAS & SATA 6Gb/s models for configuration 
flexibility
Self-Encrypting Drive (SED) options for  
HDD-level data security 
Applications/Environments
High-density data centers
Massive scale-out data centers
Containerized data centers
Nearline storage applications
Bulk storage
Enterprise and data center applications 
where density and capacity are paramount
Innovation for Next-generation, High-density Data Centers
HGST delivers the world’s first hermetically sealed, helium hard drive, the Ultrastar® He
6
for massive scale-out environments. Why does helium make a difference? Helium
has only one-seventh the density of air. Replacing air with helium inside a hard
drive dramatically reduces the turbulence caused by the spinning disks, cuts power
consumption and results in a lower temperature within the disk drive.
The reduction in turbulence for the spinning disk allows HGST to deliver a seven-disk
design in a traditional 3.5-inch form factor. In addition to being the world’s first helium-
filled hard drive, HGST Ultrastar He
6
is also the first hard drive in the industry to offer a
6-terabyte capacity. This design provides a 50% capacity gain and still reduces the energy
needed to run the drive by up to 23%.
TCOptimized™ – Driving Down Data Center TCO with Helium
The amount of data that companies need to store is growing exponentially, but IT
budgets remain flat. With 6TB, a low 5.3 idle watts, a reduced weight of 640g, and
running at 4-5°C cooler, the new Ultrastar He
6
lowers data center total cost of ownership
(TCO) on virtually every level. Key TCO benefits when compared to a typical 3.5-inch, five-
platter, air-filled 4TB drive* include:

Technology Innovations Make it Happen
Through HGST’s innovative and patented HelioSeal process, the Ultrastar He
6
drive is
the industry’s first hermetically sealed helium-filled HDD that can be cost-effectively
manufactured in high volume. This unique sealed-drive platform provides a path for higher
capacity storage for decades to come while significantly lowering customer total cost of
ownership (TCO). The inherent benefits of helium enable HGST’s new 7Stac disk design with
6TB, making it the world’s highest capacity HDD with the best TCO for cloud storage, massive
scale-out environments, disk-to-disk backup, and replicated or RAID environments.
