Seagate on Tuesday hoped to claim the distinction of having the fastest eco-friendly hard drive available by shipping the Barracuda Green. Formerly known as the Barracuda LP, the drive turns at 5,900RPM versus the 5,200RPM or 5,400RPM of most other disks while still reducing the power consumption. The 3.5-inch unit is simultaneously environmentally friendly in its actual materials, as it has low use of halogen and is up to 70 percent recyclable.
