A compact flash card that keeps its promises. With a Canon EOS 7D and 8fps continuous shooting in RAW, it supports about 16 photos in a row before starting block. 1080p HD video is recorded without any problems, no stops or jerks. Download pictures to PC by the 7D is performed at about 25MB / s (a RAW image per second wholesale). In the end a very good map, you can hardly do better for the price.
