Innovation for Next-generation,
High-density Data Centers

HGST delivers the world’s irst hermetically sealed, helium
hard drive, the Ultrastar® He
ronments. Why does helium make a dierence? 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 irst helium-illed hard
drive, HGST Ultrastar He
industry to oer 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%.

The amount of data that companies need to store is growing
exponentially, but IT budgets remain lat. With 6TB, a low 5.3
idle watts, a reduced weight of 640g, and running at 45°C
cooler, the new Ultrastar He

Technology Innovations Make it
Happen

Through HGST’s innovative and patented HelioSeal process,
the Ultrastar He
sealed helium-illed HDD that can be cost-eectively manu­factured in high volume. This unique sealed-drive platform
provides a path for higher capacity storage for decades to
come while signiicantly lowering customer total cost of
ownership (TCO). The inherent beneits 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.
