I have a Canon R3 where I transfer my RAW files from Camera to Windows PC.
If I use USB-C cable from PC to Camera, the copy speed is approx 50MB/s (usb 2 speeds). If I plug in my CFExpress card reader, and plug in the card to PC, it copies from the reader at around 850MB/s or about 7gbps (USB3.2 Gen 2 speeds). So my PC USB port, hard disk and USB cable speed are not the bottleneck. I'm using the same USB-C 10gbps cable for both scenarios.
The R3 is meant to have a USB-C 3.2 Gen2 port which supports 10gbps supposedly. Is there some reason I cant seem to copy files using direct USBC cable from camera to PC?
Spec on Canon website: SuperSpeed USB 3.2 Gen 2 USB C connector
I can't get my head around this. Is it a setting in the camera to enable faster USB? I couldnt find one. Tried various high speed usbc cables, same result.
Do others here successfully get high speed usb 3.2 gen 2 speeds direct from their Canons EOS R cameras or use card readers?
