The camera takes an SDHC card. 10 class is the best to use. I have a 32gb card and it will hold over 7000 pics or over 3 hours of video mix matched but you get the idea :-)... Great camera, I have had 2 others in the tough series and this is the best one cause the lens is in the middle and not at the top like the others where you finger can get in the way. Takes time to learn the features. Wonderful pics and video underwater. only thing I can say I don't like is the other series have a closed cover when the camera is off however this one does not have a cover at all. Hope this helps.
