How to use

Regularly back up important data to a separate storage device to prevent accidental loss.

Recommendations

For reliable 4K capture and continuous RAW shooting, use this card in cameras that support UHS-II speeds and select high-bitrate recording modes only after confirming sustained write performance. Maintain firmware updates for your camera and use a dedicated compatible card reader for fastest transfers. Store the card in a protective case when not in use and avoid exposure to extreme temperatures, moisture or strong magnetic fields.
