Yeah this. We have a Synology NAS and it's been running for four years trouble-free. It's a little sketchy for use cases other than its core purpose, but if you only try to use it as a smart reliable RAID disk with an Ethernet port you are going to have a great time.

Their Synology Drive app is a drop-in Dropbox/GDrive replacement too. Works great on Mac at least. Haven't tried Windows yet.

We maintain an official ZeroTier package for it too, so it works anywhere.
