The recent release of the Raspberry Pi 3 and now Western Digital's new dedicated PiDrive makes the argument for buying a couple of Pi 3s even more compelling.

The 314GB drive, which will normally cost $45.81 but is currently available for $31.42, is a 7mm-high drive based on the basic Western Digital Blue drives that still ship in many budget and mid-end laptops and PCs. The difference is the interface, which has been changed from SATA to USB and is designed to connect to the Pi directly without drastically increasing the footprint of the device. WD says it has customized the drive in order to "reduce the electrical power load of the hard drive on Raspberry Pi while still maintaining sufficient performance to deliver maximum USB data transfer rate." It's also a cheaper solution than the 1TB PiDrive kit the company already sells for $79.99.
