That’s right, 2TB. See, that’s why SSDs have a bit of a ways to go before they can challenge traditional disk drives. But that too appears to be changing.

HotHardware put Western Digital’s mammoth Caviar Green through its paces to determine if the capacious SATA hard drive can deliver on the energy savings.

The Western Digital Green Power 2TB delivers as promised with around 6 watts of power usage at idle and 10 watts under load. The closest competitor (counting out the 2.5″ Velociraptor) was the Seagate 7200.11 1TB that used 8 watts at idle and 12 watts under load. Although this may not seem very significant it represents power savings of 25 and 17 percent respectively.

You’ll be pleased to know that it delivers on performance as well.
