Isn’t that basically just a commercial NAS? Go buy a Synology NAS, or get fancy w/ TrueNAS. You don’t need an entry-level enterprise-grade router at all, you can just plug the NAS in anywhere and you’re golden. You can usually install a few services like Plex/Jellyfin or HomeAssistant alongside the data storage if you like.
If that’s not going to work for you, you probably have a good idea of what will work for you. For me, a tiny x86 server isn’t going to cut it, because I want a beefier CPU to run CI/CD for my programming projects, so a beefier, modern CPU is quite valuable. That’s totally overkill if all you want is a simple streaming setup with 1-2 transcoded streams.
So I think there are two main markets here:
just give me something that works - these will flock to pre-configured solutions, like Synology or TrueNAS
I want something specific - they’ll DIY components together to build their own custom solution
The only other group I can think of is the group that can’t afford 1 and doesn’t know enough to do 2, but I really don’t think that’s a particularly big group, and they’d be better off reusing something they already have instead of getting some off-the-shelf solution.
I could absolutely be wrong here, that’s just my $0.02.
