Synology seems to further favor their “own” (re-labeled, Toshiba- and Seagate-produced) drives instead of the numerous other once which still appear in the official HCL like we knew it over the years, starting with the 25-Plus-models.

Just speaking for myself here, but as someone with only basic literacy in networking and almost zero prior experience with Linux or Docker, I found Unraid extremely straightforward to spin up–especially with the numerous guides floating around on Youtube. I started out with a used SFF PC that cost about $120 and a few drives I had lying around, and was up and running with basic NAS functionality in an afternoon.
I’ve mucked up a few things trying to do something more advanced without fully reading up, but I haven’t had a single hiccup with Unraid itself.
1.5 years later, and I’ve got ~80TB worth of refurb enterprise drives and hosting several media and other storage services, and I don’t see myself outgrowing it anytime soon.
