Try and avoid saving more than 15 projects / site names on one card. Every so often, format the memory card this is generally a good idea and can aid saving times.
Using multiple cards is always a good idea, just incase you happen to lose one. Although you can store many hundreds of results on one card, spreading them across multiple cards reduces your liability in case one gets lost.
