I upload large files to our One Drive for our customers. For years we burned DVD's then used thumb drives and FedEx. Now we just click a button.
I upgraded to the fastest speed Cox cable has. They call it Gigblast, but that is a lie, or pure advertising BS. I have never seen more than high 900s for download. And it is capped at 35 Mbps for upload.
Just recently I downloaded aerial coverage for the entire state of Oklahoma, all 77 counties, and that was just under 60 GB. I took most of the day to download. We use it for the "base" of setting up a new flight and picking the boundaries of the new flight.
