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 the industry’s leading 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 industry-leading power eiciency (Watts/TB)
and no-compromise performance, the Ultrastar He8 lays the foundation for
future growth in massive scale-out environments.

TCOptimized™ – Increasing Storage Eiciency
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 the best TCO value proposition and delivers greater
storage eiciency with breakthroughs in capacity, power eiciency and
best-in-class 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. He8 oers
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.

Data Security with Industry-Leading Quality
and Reliability

Compliance and privacy requirements drive the need for increased data secu­rity. Ultrastar He8 oers 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
1402 certiication, 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. HGSTs 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.

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.
