Im planning to get a Sandisk 32gb 90mbps CF card. I wanna pair it up with a 32gb SD card. I dont know which one to get the 45 or 95 mbps. I read here somewhere that the SD slot of the 5d MK iii is slower than the CF and if i use a 95mbps card I will only be able to use it at 45mbps. Is this true? Which one did you guys choose to use for your camera?
