How to use

Insert the card gently into the SD card slot of your camera, camcorder, laptop or card reader until it clicks into place. Format the card in the host device before first use to ensure compatibility and optimal file system settings; use the device’s format option rather than operating system format tools when recommended by the device manufacturer. During recording, monitor available capacity and file system warnings on your device; avoid removing the card while data is being written. For file transfer, use a compatible SD card reader or the host device’s transfer utilities to copy or move files to your computer for editing and backup.

Recommendations

Use the card for projects that require sustained write performance such as 4K video or multi-frame burst modes. Keep important data backed up to a second storage location and avoid exposing the card to prolonged direct sunlight or extreme heat. When transporting, store the card in a protective case to reduce the risk of physical damage or loss.
