For me, the only use of 2 cards is to shoot the same data on both cards. Insurance against card failure. I have been burnt before and will work only with cameras with 2 card slots and record identical information on both. I learn lessons and do not repeat my mistakes.
Have you had a SD UHS-II card fail?

C-Fast failed. In Jerusalem. I was shooting an assignment on 1dx2. I realized at 4 pm that the card was not working. I was to film the next day. You have no idea how I managed to get a replacement. I had to have a photographer drive from Telaviv to get me his card. It was a rough rough evening.

You didn't need a failure to desire a system with a backup for redundancy to have peace of mind. I could use a single slot body, I don't NEED two slots but I have them and use them creatively, not for work/insurance/security. But I would not begrudge anyone who desires such a plan. It's silly to try and find holes in anyone's workflow. Do we all have to be the same? Please god no.

Please point where I put down anyone's plan? Where did I find a hole in anyone's workflow? LOL.

I was agreeing with you, I understand how responses to posts are typically argumentative in nature (as yours mistakenly was) I guess I did not write my feelings clear enough to convey the meaning. I apologize.

I was being a bit sarcastic. I thought my point was crystal clear and that you should have picked up immediately that I was on your side of the discussion and just adding to it. But as with the internet you never know about context/inflection or if it is someone's 1st or other language. The problem with a keyboard? No gesticulation. Good night.

Stupid Canon! They should have included 2 UHS-ll slots and 2 CFExpress slots for redumbnancy...
Maybe a grip with 8 card slots of various types! (Except Memory Stick of course) lol.

But I understand what you are saying, and if you dont make photojournalism, sports or that wedding services, so it´s a good idea to shoot raw to both cards. We never know....;)
Yep, I was talking about my own workflow, my point was, everyone needs different setup, e.g. raw+jpeg or raw+raw etc.

As a side note. I haven't shot weddings but I've shot concerts and events and always used raw|raw in parallel. If I were shooting weddings, I'd also be using raw only. I never show unprocessed images to the clients and to anyone, unless it's for educational purposes. jpeg = unprocessed for me, because the genres/styles I shoot require artistic postprocessing.

Photojournalism/sports may be a different story.

SD is not going to let you pull off 12/20 FPS 40+ MP/s. It's also going to greatly slow down dumping the data onto you computer.
There are UHS-II cards that can be read at 300MB/s. What drive can have data written to it at that speed? Then, nobody can post process images at 12 / 20 fps, so what does it matter anyway?

1gbs per channel write speed for CFexpress
640mbs for gen 2 UHS II Write speed. The camera will write at max speed of the slower slot if used togerher. Has been always the case.
I don't know camera architecture, but you could potentially use a dual bus and dedicated memory to deal with the slower speed of the SD card. I doubt Canon is going to release a high end camera that degrades the performance to the lower value. I have used this approach with my 1dx II (granted with a CFast card) when I wasn't carrying a laptop on the trip. I didn't use the approach that often since I didn't want to buy a lot of CFast cards for backup:
  • Buy 2 128GB Cfexpress cards
  • Slot 1 (Cfexpress) 128GB Write RAW
  • Slot 2.(SD UHS II). 128GB Write high quality Jpeg for loading on my iPad for review
  • At the end of the day insert fresh SD "backup" card and use Image Copy to create a backup of the 128GB Cfexpress card. You couldn't even use one of the slower UHS I cards if you had time and didn't want to buy the more expensive cards.
