The inefficiency of this transfer process is astonishing to me so far, especially given OneDrive allows for a whole terabyte of storage. The initial few files uploaded quickly, but now its only uploading about 100 MB per hour and it looks like the process will take many days to complete. It is about 70 GB worth of data and contains 140,000 files. I've finally gotten around to Cloud storage (OneDrive), and am adding all the files on my 2019 MacBook Pro to the OneDrive folder.
