Review on SanDisk 128GB Ultra UHS I Memory by Christie Cox

This card wasn't fast enough for my Canon T3i even at 720p. I kept getting an error on my camera "Movie recording has stopped automatically" after about 10 minutes of recording and my firmware indicated that the camera temperature was very high (over 70 degrees C). I've researched the issue and seen people saying it might be a card that isn't keeping up. In fact, I downloaded an SD card speed tester app and my old 32GB SanDisk U3 card recorded over 90MB/s while this card was running at around 30MB/s. Even my old Canon needs at least 40 MB/s. I don't know what use such a card is today because my camera is 9 years old and this card is not fast enough for it. Get a U3 card and avoid hassle.
