Fujifilm X-T30 and Sandisk Extreme Pro 128GB SDXC Card 128GB 170MB/s V30 UHS-I U3
Average speed is 15.6 MB/s.
I am using a usb 3.1 gen 1 cable plugged into a usb 3 port to transfer the photos. 15.6 mb/s no where near what is neither advertised for this sd card nor usb 3 speed. What am I doing wrong? Maybe an sd card reader would be faster but are these speeds normal?
