from the previous high of 1 TB—thanks to the capacity-
boosting power of perpendicular magnetic recording
technology.

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.
