Western Digital offers its Western Digital 1TB PiDrive Kit, model no. WDLB001RNN, for $51.99 plus $5.99 for shipping. That's tied with our mention from two weeks ago, $28 off, and the lowest total price we could find. It's compatible with Raspberry Pi Model B+ and Raspberry Pi 2 Model B and includes a 1TB hard drive, microSD card with adapter, and USB WD PiDrive cable, which eliminates the need for a USB hub.
