Recording 4K UHD Video and Photos
- High-Speed Capture: This card supports UHS Speed Class 3 (U3) and Video Speed Class 30 (V30), guaranteeing a minimum sustained write speed of 30MB/s. This is essential for smooth, uninterrupted 4K UHD video recording and rapid-fire sequential burst mode photography.

Maintenance
Proper care and maintenance will extend the life and performance of your SanDisk Extreme Pro SD card.
- Physical Handling:
- Avoid touching the gold connector pins on the back of the card.
- Store the card in its protective case when not in use to prevent dust, dirt, and static damage.
- Do not bend or apply excessive force to the card.
- Write Protection Switch: The card features a small write-protection switch on its side. Slide it down to protect your data from accidental deletion or modification. Slide it up to enable writing.
- Formatting: Periodically reformatting the card (after backing up all data) can help maintain optimal performance and resolve minor data inconsistencies. Always format in the device you intend to use the card with.
- Environmental Protection: While the card is designed to be temperature-proof, waterproof, shockproof, and X-ray-proof, avoid exposing it to extreme conditions unnecessarily.
Troubleshooting
If you encounter issues with your SanDisk Extreme Pro SD card, consider the following troubleshooting steps:
- Card Not Recognized:
- Ensure the card is fully inserted into the device's slot.

- Try inserting the card into another compatible device or card reader to determine if the issue is with the card or the original device.
- Clean the gold connector pins gently with a soft, dry cloth.

- If using a card reader, ensure it is a high-speed USB 3.0 or newer reader for optimal transfer speeds.
