I bought three such cards for video surveillance systems at the office (we have cameras that write not to a hard drive, but to a microsd). I can’t get to the bottom of the cards, they have been working 24/7 for several months now, sometimes I take pictures to check, but everything is good. I didn’t have to configure them additionally after purchase, I inserted them and everything “started up”. Class 10 cards are enough to record video with a normal bitrate, I did not see a low frame rate on the recordings, bugs and jerks either.
