You all keep upping the requirements here. We went from shooting video to 4K video to 10GB+ 4K video files to 10GB+ 4K files on someone else's computer.
All I said is that I shoot more video than the average person, don't use cables for data transfer, and almost never have to wait for the videos to transfer. It works for me.
If you prefer to use cables in your workflow, good for you!
How long did the 10GB file take to upload to the cloud in your situation? At average 4G speeds, it should take 20-30 minutes. Obviously much faster with wifi or 5G. Hardly "ages". But, of course, if you are in a bad service area this may not work for you.
