I'd generally agree, with the caveat that running a video editing workflow off of a NAS/SAN would want all the speed it can get, which is 10GbE at this time on MacOS/iPad OS (AQC107 chip).

So for copying files over it's bit slower, but for working with stuff it could be a pretty big issue. I really don't know; I haven't tried it as my iPad Pro is an earlier non-TB model.
