How to use

Insert the MicroSDXC card into the device’s microSD slot in accordance with the device manufacturer’s instructions and orientation. For devices that require a full-size SD card, use a compatible microSD-to-SD adapter. When first using the card, verify that the host device recognizes the full 256 GB capacity; if necessary, format the card in the device using the recommended file system (exFAT is commonly used for capacities above 32 GB) after backing up any data. Transfer files using a UHS-I compatible card reader to achieve the specified read/write performance.

Recommendations

Use the card in devices that explicitly support microSDXC and V30 performance levels for reliable 4K recording. Regularly back up important data and avoid removing the card during active read/write operations. Store the card in a dry, static-free environment when not in use and follow the device manufacturer’s guidelines for formatting and compatibility.
