Hehe, yeah, my post was maybe a bit too sci-fi like

, but just to make clear, I'm not copying over a network drive, just a normal drive in the pc (from one HDD to another).
I've tried to copy it simply through windows explorer, but the result is similair, except now it was reading at a much higher speed (50-90MB/s).
After it stops, the value in the Read(B/min) column slowly decreases until the whole process disappears, and then everything is back to normal.
Here is a screenshot about it:
