What could be the causes of variations in the speed of file transfer (copy&paste) of large data (multiple video files) from my computer to an external device?
I notice huge differences in speed, but this does not seem to be triggered by the use of other programs, like internet browsers. I am talking about one single such transfer (not multiple parallel transfers).
I noticed the large transfer speed while Firefox was running, and then, without other applications, the speed may drop to about 8 MB per sec and lower.
