Samsung has announced what it claims to be the "world's highest-density, environmentally friendly" 3.5-inch desktop hard drive. The EcoGreen F4EG has three 667GB disks for a total storage of 2TB -- a capacity that previously required four 500GB platters. The company says that this translates to a 19% performance boost in standby mode and 23% less power consumed in standby than its four-disk predecessor, the F3EG.

Power consumption for standard read/write mode is 6.3W, but that drops to less than 1W when in standby or sleep. The F4EG connects via SATA 3Gb/s, has a 5400RPM spindle speed, a 32MB buffer, an average seek time of 8.9ms with a latency of 5.52ms, and it utilizes technologies such as SilentSeek and NoiseGuard to reduce acoustic levels. Both 1.5TB and 2TB units will ship in September to the US and EU. An MSRP of $120 is mentioned, but it's not clear what capacity that's for.
