I’ve got a 2-bay QNAP and to be honest it is bloody baffling.
Trying to do (in my head what should be) the simplest thing on it takes ages of online research and ploughing through user guides.
If I bother replacing it at all, I would probably give Synology a try.
Mine is an entry level model too, and I would consider going for something with a bit more oomph.
It takes ages to do stuff and just runs slow all the time.
I primarily wanted it as a storage solution and thought it would be good for sharing family pictures etc. with the erm, family. I still haven’t figured out how to do that.
But all of my files are on it and the back-up is reliable. It’s also set-up to sync my phone pics immediately, so I don’t have to worry about losing a load of pics if I smash my phone or it gets nicked.
