I know what I’m doing, and I don’t want a NAS. I have a 4Tb M.2 as my boot & games drive, and 2x 14TB HDD for Media. I have Plex installed and it’s great.
Most people don’t need a NAS. Unless you’re running a full network setup like Linus, a NAS isn’t needed.
I can watch stuff on my PC, or I can cast to the living room TV, while the missus casts to the bedroom PC.
It’s not really a convenience if you’ve never set one up, not technically minded, and are just after some media storage.
You’ll be telling him to install some Linux distro next.
