Dashcams put a lot of wear and tear on memory cards and so I generally recommend a proper high endurance card specifically designed for being written to constantly. The Samsung 128gb Pro Endurance cards and Sandisk 256gb High Endurance cards are two solid picks.
Manufacturers often sell their own branded memory cards, but they tend to be more expensive. Third party endurance cards from reputable manufacturers are a much better bang for the buck.
It’s also good practice to periodically format your dashcam’s memory card too.
