HelioSeal® Delivers Twice the Capacity Using
One-Quarter Less Power
One-third more capacity and 23% lower energy consumption. Available today.
That’s the power of helium. Delivering high capacity at 8TB, Ultrastar He8 is
based on the widely accepted and proven HelioSeal® platform. HelioSeal
technology replaces air with helium inside the drive, reducing air turbulence
and enabling 7Stac™, a seven-disk design in a traditional 3.5-inch form factor.
Ultrastar He8 goes beyond what any air-based HDD can do and seamlessly
integrates into virtually any mainstream enterprise environment. Cooler and
quieter with excellent power eiciency (Watts/TB) and no-compromise performance, the Ultrastar He8 lays the foundation for future growth in massive
scale-out environments.
TCOptimized™ – Increasing Storage Eiciency
to Drive Down Data Center TCO
We recognize the growing pressures that data centers face. Volume is
expanding, operating costs are rising while budgets remain lat. Lowering the
total cost of ownership (TCO) has become the focus of data center architects.
Ultrastar He8 provides a unique TCO value proposition and delivers greater
storage eiciency with breakthroughs in capacity, power eiciency and
performance. This HelioSeal hard drive achieves up to 3X higher random write
performance than the prior generation, Ultrastar He6, thanks to HGST media
cache architecture, a disk-based caching technology. Designed to handle
workloads of up to 550TB per year, He8 oers a 12Gb/s SAS (6Gb/s SATA)
interface for easy integration into high performance data centers. Features like
Rebuild Assist dramatically reduce RAID rebuild times and maintain system
performance during the rebuild process. Learn more in our Rebuild Assist
technical brief.
Data Security with Industry-Leading Quality
and Reliability
Compliance and privacy requirements drive the need for increased data security. Ultrastar He8 oers security and encryption options to protect data from
unauthorized use. Instant Secure Erase (ISE) models expedite drive redeployment and retirement. Encryption models protect data with hardware-based
encryption, including a Trusted Computing Group (TCG) option with FIPS
1402 certiication, Level 2. The Ultrastar He8 extends HGST’s long-standing
tradition of reliability leadership with a 2.5M-hour MTBF rating and a 5-year
limited warranty. HGST’s drive reliability and security options also help lower
data center TCO.

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.
