HotHardware.com posted a preview on the WD 2TB Caviar Green Monster Drive

Today Western Digital is announcing their WD20WEADS drive, otherwise known as the WD Caviar Green 2.0TB. With 32MB of onboard cache and special power management algorithms that make use of that cache to balance spindle speed and transfer rates, the WD Caviar Green 2TB claims a top rung spot on the density-per-square-inch and power-efficiency ladder.

We've had an engineering sample here in house for a few days and have done some preliminary testing on it.
