Luckily, Michael Moncur of The Gadgets Page has been kind enough to put together an excellent guide to help you navigate the terrain. His Understanding SD Flash Memory Card Speeds article will take you through the topics of Understanding SD Card Speeds, Understanding Available Options and then help you decide Which one do you need?

Michael finishes up with the sage advice of choosing one of the better name-brand cards over the cheaper generics. With the potential of having 500 or more photos in transit during a transfer, you don’t want to take chances with an iffy card.
