For years, the 1-series has offered four different card usage options: "pick a card", "duplicate", "different formats for different cards", or "sequential". As far as I know, the weak link is the write speed of the memory card; my understanding is the camera is done with the image file in milliseconds and throws it in the buffer.

Could Canon "do better" by offering a fifth card usage option: "striped"? In other words, put image 1 on card 1, image 2 on card 2, image 3 on card 1, back and forth, thereby doubling the effective write speed of the cards in use.

If in fact this is reasonable, how do we funnel the idea to someone at Canon who will listen?
