I needed a card for my Nikon D5100 with firmware hack. So in the video mode, recording in HD with 54 Mbit / s is possible, provided that the memory card comes afterwards incurred data also to save. From experience, I'm always a bit skeptical about the values given and have me here on the test in the User ratings leave (thank you for that!).
Conclusion: The card's hot! Works 1A well in the smartphone and is fast. Price / performance and warranty match, for 5 star.
