That ease of outside LAN access poses a big risk tho. Plex can and eventually probably will share, be forced to share, get hacked etc Those cloud accounts imply the possibility of very detailed reports about who’s streaming what, when, where, from which source…
It’s quite easy without docker to get lots of it running with a dietpi install. Runs on rpi and alike, but also on any “normal” old low end pc. Just select jellyfin, arrs, … It handles it all for you, no need to learn Docker (I know people will argue about the advantages of docker, which are valid points, but ease of installation is more important to many people). The only difficulty remains the streaming outside your own LAN (because it’s risky). VPN, tailscale, … there’s options but it always keeps on feeling risky to open up outside LAN. Local setup for jellyfin can be really really easy tho, if it’s just for yourself and you mostly watch at home anyway… And in some jellyfin compatible app like Finamp and Streamyfin you can just download a few music albums, episodes or movies to your phone before you travel…
Purchase in your region so you can have a look at it and back out if hardware looks damaged, very dirty or not well handled by previous owner. 2nd hand is usually fine for most hardware, people sell because they upgrade or because win11 not supported, not because it’s broken.
SSD’s as far as I know mainly degrade from writing, not so much from reading or idling. If you fill an SSD, delete all files, write again, delete, etc, that is when they can wear out fast. If you’re just stacking on top slowly filling it and occassionally reading from it, it should theoretically last for many years. I don’t buy brands i’ve never heard about before and I read many customer reviews. Slightly higher price for way better reviews wins. Reviews like “it’s too slow” are not very relevant to me. Reviews like “I used it twice, got very hot and smelled like fire, broke, lost all my data”: those are the important ones. I never buy latest generation tech, I buy older generations. They’re cheaper, but more importantly they have more review information available about what you can expect from it slightly longer term.
I avoid buying anything from aliexpress, amazon, … out of principle, don’t want to support those foreign (Europe) giants. Any other webshop might get my order if they seem okay to me.
