Wow. I knew that 1TB SATA drives were down below US$100 but here is one with an enclosure for US$80. What a deal. It would be a very nice Mac OSX Time Machine backup disk for someone. I guess the drive is also "green" although I'm not sure what that really means these days.

Fantom Drives GreenDrives yield average drive power savings of 4-5 watts over competitors' drives while maintaining solid performance. That power savings equates to reducing CO2 emission by up to 60 kilograms per drive per year - the equivalent of taking your car off the road for 14 days each year.
