Saving a download to a drive is not the same as syncing to it
Selecting an external drive in a browser’s Save dialog makes it the destination for that download. It does not make the drive a suitable location for the active OneDrive sync folder. Microsoft says removable USB drives are not supported as the OneDrive folder location and notes that Folder Protection cannot be set up with OneDrive on external memory. Its instructions also describe filesystem requirements for supported external storage. Microsoft’s external-drive guidance.
For a separate backup or copy, download or copy files onto the external drive. Do not relocate the active sync folder there on the assumption that choosing it once as a browser download destination makes it supported for ongoing sync.

For OneDrive web copying, Microsoft lists a limit of 2,500 files at a time. That is a copy limit, not the ZIP download limit.

Microsoft recommends syncing no more than 300,000 items across cloud storage for optimum performance. A public preview supports up to 1,000,000 items per instance on qualifying Windows devices with specific requirements; this is preview guidance, not a general download limit. Microsoft’s limits page.
When files are shared or the account is managed
Shared files and work or school accounts can behave differently from files in your personal OneDrive. Confirm that you have access before starting a large transfer. If a shared item cannot be downloaded from the Shared view, open it and save a copy where permitted. An organization may also apply controls that limit downloading or copying.
