I have a Sandisk Ultra II 2gb compact flash card for my 20D and it is very fast. A friend has an Olympus E-10 and he wanted to know if the faster card would allow his camera to write faster. We tried my card but we didn't format it as it had pics on it already. It didn't seem to be any faster. Would it be faster if we formated it with his camera or is he just out of luck?
