I've read searching this forum that Shareport supports multiple external storage devices over USB hub and can share them all simultaneously. It would seem logical that this would be true for USB3 on this device also, but I can not find documentation to support this anywhere.

I currently have 6 x USB3 3TB HDDs connected to 2 x USB3 hubs on a microcomputer. I don't like having to manage my files on a software OS, I would prefer an embedded NAS solution such as the DIR-857.
In the end, it all comes down to a single blue USB3 cable -- and from what I've read, searching on this forum, Shareport seems to support multiple storage devices being shared simultaneously. But, as the price of this router is not cheap, I really want to make sure this will work prior to making this purchase!
Thanks!!
