I’ve been running a Buffalo 220, 2 bay drive for over 6 years now. I use it to host my Plex media non-stop for that time. Only issues are sometimes when there is a power loss, it gets unmounted or gets reassigned a new IP from the router, but thats mostly me not assigning a static private IP. I believe the one I have only allows for max 8TB but I think it can go up to 16TB. Do not know what the prices are in EU but it similar or slightly cheaper than Synology in price. https://www.buffalo-technology.com/productpage/linkstation-ls220d/
I wonder if this is because of their ads partnership they have with Microsoft atm, they kept that avenue open by relying on their engines and security updates??
