The Eco-Friendly Choice
The Seagate
®
Barracuda
®
7200.12 drive delivers power
savings without sacrificing performance. Customers
can manufacture eco-friendly PC 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.
Customers can have the best of both worlds—top hard-
drive performance and a high-capacity drive with a very
small eco-footprint. Seagate minimizes the impact of
our products and operations on the environment with
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. This delivered a 158.93 million kWh savings in
six months, 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.
The Barracuda product family complies with the
RoHS directive on hazardous materials.
