CFExpress Camera Cards to Take Over? Downloading a Big Shoot on SDXC Painfully Slow vs CFx

Rexcently out in my Sprinter van in the middle of nowhere, I had 160GB or so to download. Having configured the Fufjiflm GFX100 II to record both to SDXC and CFExpress Type B cards, I had my choice of which to download.
I inserted the OWC Atlas Ultra SDXC card into the built-in slot of the 2021 MacBook Pro M1 Max... "time remaining: 30 minutes". Uggh... I needed to get moving ASAP—unacceptable. And that’s without the needed backups. Time matters when sunset comes early and you need to be somewhere to shoot.
I pulled the SDXC card, attached the OWC Atlas FXR Thunderbolt card reader, inserted the OWC Atlas Ultra CFExpress Type B card and the job was done in about 2 minutes. WOW! While it’s more convenient to use a built-in card slot, I am not going to wait that long for a download. CFExpress rocks.
And for a blazingly fast backup (even faster), I backed-up stuff to the OWC Envoy Pro FX SSD.
SDXC vs CFExpress
SDXC is at the end of its road.
Little but some variant of CFExpress Type A will exist within a few years since the larger form factor of CFExpress Type B is too large for smaller cameras and likely won’t be needed at all within a few years. And CFxA is small enough to make built-in laptop readers feasible, whereas CFxB is not.
For example, the Fujifilm GFX100 II has one CFExpress Type B slot and one SDXC card slot, a situation that ultimately is likely to move to dual CFeA cards in some future camera.
