without sacrificing performance, giving
customers the ability to manufacture
eco-friendly PC systems and external
storage systems that meet energy-
savings requirements.
The drive combines proven technology
with expert manufacturing to deliver
up to 1 TB of desktop storage. With
the Barracuda 7200.12 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.
