I'll have another look but there should be no reason to the file being buffered.

There will be an update one of these days as generating the checksum has been optimized. (a bit faster)
Ah, moving the source file to another drive has fixed the md5 testing

I will post an update in a few hours ... let speeds somewhat stabalize again.!
