  • Just to be clear, I photoshopped in the red bars. They're not Windows UFOs or anything.

  • I'm guessing that one of those is a network drive?

    By the way, note that 150Mbps is the best you'll get if you only have one wifi antenna. To do better, you need a card with 2 or 3 antennas.

  • My first guess would be that the very act of displaying data causes the slowdown because it means that Windows has to inspect the data instead of just shoveling it through. It would be interesting to see if you have any speed reduction if you run WireShark during the transfer instead of Resource Monitor.

  • @MosheKatz Camo is a desktop system and Steel is a laptop. The drives being directly connected (internally) to each. I've got an ASUS Maximus Vi board which come with an on board MPcie combo card with dual anttennas so I think I should be covered. If you guess is correct then I would never want to see a progress dialog given the drastic effect it has on transfer. I cant see why Windows would need to inspect the data, i thought all these graphs were driven off WMI anyway.
