If you’re dealing with this much storage, it’s time to upgrade to a rack. Don’t deal with having to shove 10 drives into a packed full-size.
Start scouring 2nd hand auction sites and buy one used. They’re pretty cheap as far as solutions go if you can grab them used. Something like this would be ideal: https://www.silverstonetek.com/en/product/info/server-nas/RM22-312/
Probably just easier to nix the Prime subscription and just download scene releases… Most of them are h265 these days and are released same day as on Prime.
I just checked a list of “new to prime” and my tracker and they were all there. No reason to give money to Amazon.
