If you don want to pay a king’s ransom to outfit your PC with an energy-saving SSD — or you simply might not want to make the capacity trade-off — the next best thing to do is invest in an energy efficient hard drive.

Seagate is countering Western Digital’s Caviar Green line of hard drives with new the Barracuda LP line. Anandtech has the details:

Based on Seagate’s internal testing (review samples arrive shortly) the drives are rated at 19dB(A) at idle and around 20dB(A) under load. This compares to the WD Caviar Green 2TB at 19db(A) idle and near 21db(A) under load. Power consumption is very close also, Seagate reports 3W at idle and 5.6W during operation, compared to 3W at idle and 5.72W under load for the WD drive.
