We study SD cards by trial and error! These cards are not fast enough to get the required clarity in our surveillance cameras. We thought our cameras were the problem - no, it's the speed of that SD card! Durability has also become an issue. We regularly inspect our cameras and maps are stored straight from the camera in a hard case for safe keeping. They don't live a hard life, but the plastic between the metal parts broke - and the photos were lost!
