I have just purchased a digital camera (TRUST 910Z POWERC@M OPTICAL ZOOM) and would like to buy some extra memory for it. It says in the instruction manual it will take SD or MMC memory. All I would like to know is what is the difference in SD & MMC memory? ad of course are there any advantages of one over the other??
