My research steered me away from the QNAP on throughput issues. I really wanted a Dream Machine Pro, but they we’re out of my price range.

I ended up getting an Asus RT-AX89X and a 10G SFP+ card and am pretty impressed. I saw one used recently <$200. I get about 2.3G down, 3.5G up with the various IPS/IDS programs running.

The TP-Link wasn’t really an option when I upgraded. Nothing against it, but $500 is high. Would choose a DMP over that on price alone.
