Western Digital has launched an update to its line of Mac-styled MyBook Studio external hard drives. The new units are available with power-conserving WD Caviar Green series hard drives in 1TB, 2TB, and 3TB capacities, and have both FireWire 800/400 and USB 2.0 interfaces. The drives' brushed aluminum exterior helps eliminate the need for an internal fan, which reduces noise and extends drive life. The drives are also compatible with PCs but must be reformatted.
