When you set up download for the vixo2 it will ask for the path, you can set that, and if it recognizes the device it may, or may not download to an external hard drive. You will just have to try it with whichever program you are using. I have not had much luck with most of the programs using a torrent server downloading to an external hard drive, AND be aware that IF you do download a movie it may be accessible to the copyright police. One of the primary ones is Popcorn Time. It will rat you out every time unless you rename the file and move it.
