In our hackerspace, using 3 antennas in an ubiquity "UFO" danling in front of a shelf, communicating 2~3m to a thinkpad with afaik 2 antennas, using an 80MHz 5GHz 802.11ac configuration, we get consistently >500Mbit/s (iirc hovering at roughly 600Mbit/s) (unidirectional) to the NAS (1000BASE-T wiring, 1-2 switches in-between) when mounted via NFS. A single stream can't get more than ~420Mbit/s _in the lab_.
