EOS 7D Mark II & R6ii take forever to finish writing when shooting jpg

[DavidW55]

I had the same problem with my 7Dmkii, and now with my R6mkii as well.  When I shoot RAW, I have no problems.  I can shoot up to 40 fps, and rarely fill up the buffer.  But when I shoot jpg, and the card gets upwards of 1,000 images, after shooting, or when re-inserting the card, the red processing light will blink for literally 10 minutes or more. During this time, I can shoot more images without issue, and I can view the images, but I can't rate or tag any images. I get an error message saying it isn't available, and the red light continually blinks while I'm shooting or viewing.   I'm using a UHS-II V90 with a 300mb/s write speed, so it can't be that.

No, I don’t shoot pro sports. But I do shoot amateur sports for hours on end. I might capture thousands of photos, too.  I don’t post examples because the athletes are minors.  

I don’t experience your issues. I use a 1D4 and a 7D2.  I carry spare cards in my pocket.  You made it clear that you don’t feel it’s a card issue.

I think you should consider it. Good luck.

“ How does this solve the very same problem that I'm having with the R6ii? “

It sounded like you were having issues with your 7D2.  I see that the title of the post has changed. You added 6D2, but left 7D2.

Also wanted to add that this is not something I've experienced on my T6s or 6D2, UHS-I cards ranging in size 32, 64 and 128GB.  I think you may want to seriously consider Canon Support.
