Agreed. I have a UniFi Protect setup and almost all of the equipment is top notch. I don't appreciate the lock-in inherent in the system (Protect NVR only works with Protect cameras, cameras only work with their NVR, and you can't self-host the NVR on your own hardware), but I'll gladly take it in trade for excellent spousal-approval-factor.
The one exception I've found so far is that the UNVR-4 system software in older models is stored on a very cheap USB flash drive, and I believe they write logs to it too. Mine failed a few months before warranty expired so I just replaced it with an SSD and SATA->USB 3 adapter I had laying around. Works great, is snappy, and should hopefully last quite a bit longer.
