I'm looking to get myself a NAS drive so I can free up some space on my PC, and make it so I can access my media (movies, pics, etc) across my various devices. I plan on using 4 drives, either 2 or 3 TB each (will also keep a backup of my PC), in a RAID 10 setup.
The only thing I'm not sure of is whether I should get a NAS from a company like QNAP or Data Robotics (Drobo) or should I built one myself using FreeNAS?
