Amazon has the Western Digital Red WD20EFRX 2TB 64MB 3.5" SATA3 Internal Hard Drive for $112 with free shipping. Usually goes for $120+. Made for 24x7 operating environments and as a NAS drive, the WD Red line features dual-plane balance control and consumes less than 4W of power at idle.
3 year warranty, quiet, power efficient and cool. Downside is 5400 rpm spindle speed means less performance and slower seek time. Not ideal for desktop use, great for a small home NAS.
Moving drive heads causes most of seek time, rotational latency is a minor factor. Choose between the cheapest storage in a slow spindle, baconfast storage in an SSD, or use a tiering solution (see Fusion Drive) for anything in between. There is no market space left for expensive, slightly higher performance spinning drives anymore.
