The 2.5" drives are quite expensive, and you could get a 4TB WD RED drive for $202.99, though you will need a different case, or an adapter to mount it in the 5.25" bay, if you don't need a Bluray drive.
Also of note is that while this will handle 1080p fine, it will struggle with a video renderer like madVR (depending on the settings), which can offer better video quality.
