If you're buying a 512 MB card, then most likely you need/use a lot of data storage. If you fill this card up then try to download to your computer, it will take several minutes to transfer. You should really consider getting a high-speed card so that you can cut on transfer time. Many cameras also take advantage of the faster speed on the high-speed cards; this can be especially helpful if when you take many pictures in succession.
