My SD cards are the fastest UHS-I SDXC 256 GB cards but their read speed is too slow to copy while in the field. UHS-I is limited to 104 MBps. I carry three of the cards then copy back at the tent/cabin/boat/whatever.
When you have a Dingo family nuzzling your leg in the Uluṟu-Kata Tjuṯa National Park, you do not want the delay of copying. Just swap the card and the battery as both run out about the same time.
In my camera, the 256 GB card lasts longer than the battery for pictures but less for video. So I add extra battery for each card.
I had cameras that would not work when formatted to FAT or exFAT on a computer. They had to be formatted in the camera. I now copy to my notebook then verify the copy, then backup the Pictures directory of the notebook using rsync or Backintime, then delete the images from the SD card as that leaves the original formatting.
I copy the DCIM directory to Pictures then later rename it to include the location and date.
If you build a copier using something like a Pi Zero 2, you will need a USB 3 hub for the the USB 3 disk and may have power problems. Plus you need a screen. A 2 GB Pi 4 has USB 3 built in and is much more flexible. There are battery power projects for the Pi 4. Use a box with a 5 or 7 inch Touch Screen 2. On return to camp, the Pi 4 can be a file or media server to review all your photographs on your Samsung 330 cm Micro RGB TV.![:D]( "Very Happy")
