Well I can take a 5 minute or longer video on my iPhone, then AirDrop it to my iPad Pro and go into the Photos app and save to downloads folder in Save to files. Then connect a USB C external SSD hard drive into the USB C port of my iPad Pro.
The USB C external hard drive automatically gets its power from the iPad Pro with just a USB C to USB C cable plugged in. Then go into the files app on the iPad Pro and move the video file I just saved to downloads to the external SSD drive which transfers very quickly.
Plug the USB C external SSD drive into PC and transfer file the video file across to the videos folder on PC which transfers very quickly and I'm done.
Saves me having to plug an external hard drive directly into iPhone which needs all sorts of adapters and would be limited by USB 2.0. For extremely large video file captures this should be quicker than plugging the iPhone directly into a USB A port with the USB C to USB A adapter and transferring that way.
I've also turned off iCloud for Photos on both iPhone and iPad as its just a pain.
