Olympus Type M 2GB XD Picture Card
The development of advanced video-recording functions in digital cameras and the desire for higher digital picture quality means a demand for large memory. The Olympus 2GB Type M xD-Picture Card packs 2GB of memory in to an ultra-compact media card. Using an 8 mega-pixel Olympus digital camera in HQ mode, the card will allow you to take and store approximately 1000 shots.
Quite expensive per GB, i know, but this is the biggest XD Card available and many cameras that are still perfectly usable use them.
