Data Hoarder
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
Going old school sneakernet style, 1tb or even 500gb microsd cards. Think density in small hard shelled case. You could bring more movies per inch this way
8TB Samsung SSDs are like $350-400 bucks. Another $20 for an enclosure. May be a better $/GB than 2TBs. Even at 50 gigs a piece thats 160 movies.
I have a media server built in an Apache 1800 case with four 2tb 2.5" ssds in it.
If I where doing this, I would fill a hard case with nvme drives or 2.5" ssds and put 4k remuxes if you're dead set on 4k, or 1080p remuxes, the ones on my server are 6-8 GB. Yes, you can get super high capacity ssds, but they are real expensive. The reason I have 2.5" drives in my box was price. I paid $50 for each one.
I second the ASUSTOR flash NAS. 12 m.2 slots, you can cheap out and get 4TB instead of 8TB drives for better TB/$. Has built in software/OS that’s essentially plug and play into any LAN and you won’t have to tie it to your day to day computer.
