Actually, it wouldn't help in that regard. The HD setting requires a write time that the port/hub would not keep up with so you would start dropping frames. It would take an UHS-1 card and slow it down to the speed of a Class 4 or worse. It would totally help to offload photos, videos and data to keep enough free to maybe shoot more than that to internal memory though!
