Product Summary
| 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. |
