I assume that - in case of a backup/duplicate, the slowest card will dictate the overall speed. So buffer capacity etc will be greatly reduced using a CF with SD backup (or vice versa). A jpeg backup instead of Raw will probably be quicker.

Disclaimer: I do not own an XH(s) so the above is a pure assumption.

So you just made stuff up?

From the manual:

I don't think you meant it that way, but your response sounds kind of rude.

I own the X-H2S and I understand it the same as Sjeupie. Any speed bottlenecks are dictated by the slower of the two cards. In this case, the CFexpress card is almost always considerably faster than the SD card. So, if you use both cards as a "mirror" backup (duplicate backup), SD cards with faster write speeds should theoretically help with the camera's speed.

When researching SD cards, I found the following website to be useful as a reference.

I ended up purchasing the Kingston Canvas React Plus V90 UHS-II when it was on sale.

When I shoot burst, I don't usually max it out at 40fps, so I haven't really put the card through its paces, but the SD card seems to be working great.

I hope this helps.
