The Canon R6 Mark II uses two UHS-II SD card slots. That means you do not need CFexpress, and you can get excellent performance with a good V60 card.
Quick rule: For the heaviest published video modes, treat V60 as the safe floor. V90 is optional “extra headroom,” not a requirement for most people.

How to choose (in 60 seconds)
Step 1: Buy UHS-II (not UHS-I)
Look for UHS-II in the listing. UHS-II cards have a second row of pins and are much faster for video and buffer clearing.
Step 2: Pick the video class
- V60 = the smart default for the R6 Mark II’s heavier published video needs.
- V90 = extra headroom. Great if money is no object, but most people don’t need it.
Step 3: Choose capacity
- 128GB is fine for stills-first and occasional video.
- 256GB is the best “one card does most things” size for most creators.
