Transfer from External to Hub

The fastest way to transfer files to the hub is to physically disconnect your USB drive from your hub and plug it directly into your PC or laptop. Before you unplug your drive from the hub, be sure to press the “eject” button on your hub remote. This is supposed to be a “safe remove”. Copying files to and from an external hard drive attached to your hub through a wired gigabit network tops out at around 10 MB/s. This is a little faster than wireless N, but nowhere close to Gigabit speeds. Using the hub’s Windows filesharing allows me to access all the files without requiring mapping a drive. I’m not sure why you needed to do that. Finally, I discovered a shareware program called “Extreme Copy Pro”. It seems to yield a faster transfer speed than standard Windows 7 file explorer. I hope I’m understanding your problem and this helps you out.
