The docker community support and installation is also really good. Love how its customizable, for example you can use SSD as a cache disk and set it up so it only spins up mechanical drives periodically to move data to them.
You can have a mixed bag of drives, as long as your parity drive(s) are the same size as the next biggest data drive you're good. Enable additional search results from dockerHub in the community application settings and then you can get a makeshift template for it that will appear properly in UnRaid or you can go full terminal and install the docker that way. In addition to plex server, mine has docker containers are also running nvr software, nginix/letsencyrpt, pihole and homeassistant. Started with 2TB drives, but over time went to a mixed bag of 4TB, 8TB, 10TB and now have a 14TB from bestbuy, as well swapped out the guts, added a 950GTX video card for plex 4k hardware transcoding. Easy to use/setup, great community behind it that answers any questions. To customize the container icon in the Unraid webgui, enable Advanced View and then scroll down for Icon URL. Boom- you are all done Customize the Icon Next to the Container. I know some people, perhaps you yourself, look at using the terminal in sheer horror and can’t imagine how that is easy, but when you get the hang of it, it’s. Once you get your stream setup how you like it, as soon as you Go Live you will immediately begin streaming to Twitch.
Turned a bunch of old pc parts into an unraid server several years ago. Benefits Hopefully you’ve read about the Drawbacks on the previous page, if not then I strongly advise you to read them, however there’s a few reasons why it might be worth giving up some of those niceities.
