Samsung this week said it will soon begin shipping the 3.5-inch EcoGreen-series F4EG desktop hard drive that has the world's highest density. At 2TB, it uses three 667GB platters and is said to have 19 percent better standby time performance and 23 percent lower power consumption in standby than the four-platter, 2TB model it replaces, the F3EG. The new drive is also environmentally friendly, with no halogen compounds and brominated flame retardants from the materials used in its construction.
