I use this card for about 2 months in my new Nikon D7000 SLR Digital Camera (16 Megapixel, 39 AF points, Live View, Full HD Video) housing. Since the camera can shoot 6 frames per second series, had to be a really fast card to also use the feature. I can not really test the speed, because I lack the PC hardware. With the camera I can shoot 24 JPEG images at 6B / s to a speed reduction takes place at the highest RAW adjustment figure is still about 15. When I wegrechne the buffer memory of the D7000 I come to an estimated write rate of 25-35MB / s , I had at Full-HD videos and never had any problems and can otherwise still take a second card in the D7000, when I once more than 15 RAW images need in series :) So for me perfectly adequate and cheaper than the other high-speed cards, so 5 stars
