How to use

Insert the MicroSDXC card into a compatible device slot or use a reader to connect to a computer. If required, format the card in the device before first use using the device’s storage settings or a FAT32/exFAT formatter compatible with the device. Transfer files via the device interface or card reader; when recording video, choose device settings that match the card’s sustained write performance (for example, select 4K or high-bitrate profiles only if the device supports V30-class media).

Recommendations

For reliable long-term performance, avoid full-capacity fills without periodic file organization and maintain regular backups. Use the card in devices that support UHS-I and V30-class media for best results, and format the card in the host device when switching between different device types to prevent file system conflicts.
