This Barracuda Generation Brings
a Whopping 1.5 TB
This is a drive for the ages, and it will take ages to fill it up. In
one bold move, Seagate provides the largest single capacity
jump in the history of hard drives—a half-terabyte increase
from the previous high of 1 TB—thanks to the capacity-
boosting power of perpendicular magnetic recording
technology.
The Eco-Friendly Choice
The Barracuda 7200.11 drive delivers up to 43 percent power
savings over the previous Seagate desktop generation
without sacrificing performance, giving customers the
ability to manufacture eco-friendly PC systems and external
storage systems that meet energy-savings requirements.
Like all other Seagate®drives, the Barracuda 7200.11
product family complies with the Restriction of Hazardous
Substance (RoHS) directive that limits the use of hazardous
materials in electronic goods.

With the Barracuda 7200.11 drive, our customers can have
the best of both worlds—top hard-drive performance and a
high-capacity drive with a very small eco-footprint.
Seagate is committed to minimizing the impact of our
products and operations on the environment. We have
implemented production efficiency measures, such as
replacing or renovating less-efficient equipment, resulting
in a 20 percent increase in production efficiency on a per-
hard-drive basis. In just six months this delivered a savings
of 158.93 million kWh, or enough energy to power nearly
15,000 U.S. homes for one year. Seagate also has deployed
aggressive waste minimization and recycling programs in
facilities worldwide.
