Technology Innovations Make it

Happen

Through HGST’s innovative and patented HelioSeal process,

sealed helium-filled HDD that can be cost-effectively manu-

factured 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.

HGST Quality and Service

tradition of performance and capacity leadership. The

proven drive design enables high reliability and availability

to customer data. Ultrastar quality, performance and world

class technical support and service provides customers with

a lower total cost of ownership over previous generations.

HGST drives are backed by an array of technical support and

services, which may include customer and integration assistance.

HGST is dedicated to providing a complete portfolio of HDD/

SSD solutions to satisfy today’s monumental computing needs.

Innovation for Next-generation,

High-density Data Centers

HGST delivers the world’s first hermetically sealed, helium

ronments. 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

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

ownership (TCO) on virtually every level. Key TCO benefits

when compared to a typical 3.5-inch, five-platter, air-filled

4TB drive* include:
