any other reason to wait for the pro? I’m considering getting one for my setup but not sure whether to wait or not?
Rack mounted, significantly faster throughput, 10GbE SFP+ uplink WAN port, built-in 3.5” hard drive so you can run UniFi Protect, 8 port switch, arguably better value than the UDM.
if you’re serious about UniFi, and you have a FAST internet connection, the UDM Pro is the better option.
