I just made pictures in 1071 with two cards (32 GB) to my great satisfaction. Only two photos were not recorded on the card, but it was the 5th and 6th of a burst, I work with a raw and Nikon D800 .. (or pictures of +/- 50 mb ..) and I am not sure that we should accuse the board (my Nikon seemed sometimes overheat in Martinique ..) However, I said that I never practice video and I can not therefore find these cards in this regard. Given their price, so they are recommended!
