Innovation for Next-generation, High-density Data Centers
HGST delivers the world’s first hermetically sealed, helium hard drive, the Ultrastar® He6
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 heliumfilled hard drive, HGST Ultrastar He6 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 He6 lowers data center total cost of ownership
(TCO) on virtually every level. Key TCO benefits when compared to a typical 3.5-inch, fiveplatter, air-filled 4TB drive* include:

Technology Innovations Make it Happen
6TB | 7200 RPM
SATA 6Gb/s and SAS 6Gb/s
Through HGST’s innovative and patented HelioSeal process, the Ultrastar He6 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.

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.
MTBF 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.
