USB 3.0 ports on NV+V2

You misunderstood what I said. The external drives WOULD NOT be added to the RAID volume. You said share - and they would be shared across the network, but as stand alone volumes, not part of the RAID volume. When I connected a USB drive to my NV+ as a test, I could access the USB drive (after entering a password which is not needed for the RAID volume) and see the files. That is what I meant by sharing. I do not consider the RAID volume as sharing drives, for they are configured as one large volume with multiple shares. Share in this context is the same a a first level directory/folder off the root.The external drive is shared as a drive by itself.

If you intend to share this external drive to multiple users, permissions could be a problem. I do not have users set up on my NAS unit, and had to enter the ADMIN sign on and password to gain network access. I don't know if you would want to do this in the case of multiple users.
