SanDisk Extreme PRO SDXC UHS-II Memory Card - 128GB

UHS-II (Ultra High Speed II) is a memory card interface that provides significantly faster data transfer speeds compared to UHS-I. It's crucial for professional applications like high-resolution video recording and fast burst photography where rapid data writing is essential.

Yes, the SanDisk Extreme PRO SDXC UHS-II card is backward compatible with UHS-I slots. However, it will operate at the maximum speed supported by the UHS-I interface, which is considerably slower than its UHS-II capabilities.

UHS Speed Class (U1, U3) refers to the minimum sustained write speed for general tasks. Video Speed Class (V60, V90, etc.) specifically guarantees minimum sustained write speeds required for high-quality video recording formats like 4K and 8K.

After purchasing the card, you can download RescuePRO Deluxe from the SanDisk website. The software guides you through the process of scanning the card for recoverable files and restoring them.

The V60 rating indicates a minimum write speed of 60MB/s. While excellent for 6K and many 4K workflows, 8K video recording often requires higher speeds (V90 or higher) for sustained capture. Check your camera's specific requirements.

Class 10 is a basic speed rating indicating a minimum write speed of 10MB/s. For this UHS-II card, the UHS Speed Class 3 (U3) and Video Speed Class 60 (V60) ratings are more relevant and provide much higher performance.

This card is built to be waterproof, temperature-proof, humidity-proof, wear out-proof, shock-proof, drop-proof, X-ray-proof, and magnet-proof, making it suitable for demanding field use.

Ensure the card is properly inserted. Try a different SDXC slot or card reader. Format the card using a UHS-II compatible device (note: formatting erases all data).

Verify that your computer or card reader is UHS-II compatible. If using a USB reader, ensure it is USB 3.0 or higher. Close other applications that may be using system resources during transfer.

Use the included RescuePRO Deluxe software to attempt recovery. Ensure you are using a stable power source during file transfers and avoid interrupting the process. Format the card if the issue persists after data recovery.

Ensure the card meets the speed requirements for your recording settings (e.g., V60 for 6K video). Check for firmware updates for your camera. Try a different card to rule out camera issues.
