Usage recommendations

For reliable performance, format the card in the device you will use for recording, keep firmware for your camera and card reader up to date, and maintain at least one backup copy of critical media. Store the card in a protective case when not in use and avoid abrupt removal during recording. When shooting high-bitrate formats, allow buffer clearing between long takes to maintain sustained write stability.
