I agree with his conclusions and have experienced it myself while working with clients. Trying to copy a code project (with a lot of assets) of about 300mb says it will take 3 hours to go from my laptop over wifi on their LAN to an external USB drive hooked up to their server. When I have to copy something large I always request to either unplug their external hard drive and plug it into my laptop, or copy it from my laptop to one of their desktops an then copy it to the external drive. I do think there's something fishy about going over a network to a USB on Windows.
