Best Buy has the WD Blue 1TB internal desktop hard drive for $40. That's a $10 savings off the next best price at Amazon and Newegg.

This is a great hard drive for anyone building their own computer or even setting up a network-attached storage device, like the Synology DS216J. It uses a standard Serial ATA interface to connect, has a 64MB internal cache, transfer rates up to 6 Gbps, and has a 7200 rpm speed. Those rpms are definitely an upgrade over the much more common 5400 speeds of most internal hard drives.

All new WD hard drives come with a two-year warranty as well. This same drive has more than 8,100 user reviews on Amazon giving it 4.5 stars.
