I’ve been meaning to benchmark the 3 possible methods of image transfer: fast USB-3 reader, direct connection to camera and Wi_Fi from the camera. I think I already know the answer (same as the order above), but it will be interesting to see the actual data - I’ll post it later. In terms of relatability, WIFi is the safest and after that, as said above, it’s the possibility of bent pins vs USB camera port mechanical failure - pick your poison.
Sometimes I transfer files from PC to PC over encrypted WIFI, I'm guessing that is the slowest method.
MUCH slower than the card reader.
Non-encrypted may be faster, but.....
