newegg offers the refurbished Western Digital 2TB WD Green Serial ATA 6Gb/s 3.5" Internal Hard Drive, model no. WD20EZRX, for $79.99 with free shipping. That's $0.04/GB and the lowest total price we could find for a refurb by $12. (It's also $18 under the best price we could find for a new one elsewhere. Meanwhile, we saw a new one for $10 more last week.) This drive purportedly consumes up to 40% less energy than standard mechanical drives. It features a 64MB cache. Deal ends April 4.

A 90-day warranty applies, but it's not clear who backs it.
