When it may not be suitable

This microSDXC card requires a device that supports microSDXC format and may not work in older devices limited to microSD or microSDHC. The read speed specification refers to sequential read; write speeds may be lower depending on the device and workload, so it may not be ideal for continuous high-bitrate multi-stream recording without verifying sustained write performance.

How to use

Insert the microSDXC card into the microSD slot of a compatible device following the device manufacturer’s instructions. For the fastest transfer speeds, use a UHS‑I capable card reader and a host device that supports UHS‑I. When recording video, format the card in the camera or device before first use and check that the device recognises the card’s capacity and speed class. Safely eject the card from computers or mobile devices before removal.

What to consider before purchase

• Check that your device supports microSDXC cards and UHS‑I interface
• Verify that sustained write performance of your device meets your recording needs for high-bitrate 4K or multi-stream video
• Ensure the device supports A2 if you plan to run apps from the card

Recommendations

Use the card for photo libraries, 4K video capture and mobile storage expansion in devices that support microSDXC and UHS‑I. Format the card in the target device before first use and periodically back up important data to avoid loss.
