We have listed the SD cards we are using for testing NVS-31 and NVS-33. We will keep it updated on the official site.
We also strongly recommend to use this tool: https://www.sdcard.org/downloads/formatter/ When you see poor performance on recording, sometimes the SD card has been written for too many times. This problem frequently happens on dashboard camera because of nonstop recording. To keep the recording performance, please use this tool periodically.
