Used with my Canon EOS 7D and 8fps continuous shooting in RAW, endures about 16 consecutive photos with transfer speeds quite honorable. 1080p HD video is recorded without any problems, no stops or jerks. PC to the transfers are to 30MB / S, which is very fast -plus a photo in RAW 1s. Used at the North Pole, it largely supported the conditions of extreme cold. The price is very good for such storage capacity and Transcend offers lifetime warranty on their memory cards, that's what convinced me initially. Recommended.
