Seagate Barracuda LP 1.5TB 5900RPM 32MB Hard Drive for $69.99 shipped. Here is a screenshot for your reference. This is part of Seagate’s new line of lower-power drives. Note that it comes in OEM packaging, which means no pretty retail box, but is otherwise identical. Most places have it for about $97.
