How to use

For initial use, format the card in the device to ensure the file system and allocation settings match the host device’s requirements; follow the device manufacturer’s instructions for formatting. When recording high-resolution or high-bitrate video, confirm the camera or recorder is configured to use the external card as the primary recording destination. To transfer files, use a compatible card reader connected to a computer and copy files using the operating system’s standard file management tools.

Usage recommendations

Use the card in devices that support microSDXC and UHS-I standards to achieve the specified performance. For reliable video recording, pair the card with cameras that support U3/V30 speed classes and avoid filling the card to full capacity during long recording sessions to reduce the risk of file fragmentation or interruptions. Keep a backup of important files and handle the card by its edges to minimize contact with the electrical contacts.
