Review on SanDisk 128GB Ultra UHS I Memory by Anthony Robichaud

This card wasn't fast enough for my Canon T3i, even at 720p. After about 10 minutes of recording, I kept getting an error message on my camera "Filming stopped automatically" 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 test app and my old 32GB SanDisk U3 card recorded over 90MB/s while this card ran 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.
