>That's insane. Like I mentioned in another comment, high-quality rips of 1080p movies tend to be 5 Mbps, and that's generally with a lot more detail and motion than what your camera is filming at home.
I would double that, for at least movies. Not sure if you are going to see an increase in quality in smartphone style cameras.
