I have a pretty large porn/music/video/software collection that I have amassed over decades. I'm running a jellyfin server, a plex server off of an old pentium IV pc with a couple 20tb drives in it. I started to upgrade my plex server on a new PC , but didn't get very far. Though I haven't stopped collecting data, I am just not managing it very well at all.
In my PC I have 6 drives ranging from 1TB NVME to 20TB Sata. Nothing is backed up and things are not well organized.
If you found yourself in my situation, knowing all that you know now about data storage, reliability, accessibility, etc. what would you suggest would be the best way to get my data in order and make it accessible and reliable for as little cash layout as possible. Any help would be greatly appreciated.
