G1X SD Card Write Speed -- Photos

Figuring a new camera might write faster, and therefore take advantage of faster cards, I bought a SanDisk Extreme Pro 16GB SD card, with a 95MB/sec. rating. Then I went home and tested what I already owned.

Fortunately for testing purposes, the two other cards I had were both 16GB like the new one. I formatted each card in the G1X before using, set the G1X on Continuous shooting, and fired off 20 shots before clicking the stopwatch.

SanDisk Extreme Pro (95MB/s): 21 seconds.
SanDisk Extreme III (30MB/s): 21 seconds.
SanDisk: Ultra II (15MB/s): 22 seconds.

So, basically one second per shot, shooting RAW+Large JPG.

The only difference I saw with the slowest card was that the "Busy" bar appeared several times, but it still only took a second or two more to shoot 20 frames.

Note that this is a casual test, but I performed it three times on each card. Also note that video may benefit from higher-speed cards -- I didn't test video.
