I got in one private tracker and I like that system a lot. I seed my torrents for years because I don't do a ton of very popular stuff, and I like some older shows. Like The Mentalist season packs on TG are at like a 30:1 for me because not many others seed them.
However, the private tracker doesn't use standard naming which sometimes fucks up searches and *arr, also, there are barely any seeders or leechers so a lot of media is hit or miss both downloading and uploading. Of the 50 or so things that I downloaded since I got on, 1 has a positive seed ratio, so thank mods for duration seed points...
Spinning metal storage is cheapish now, but now a 4K movie takes up a much larger amount of space.
If you measure storage by €/1 hour media with 4k HDR vs older prices and 720p, it is likely quite similar.
