Oh my God.... I'm running a jellyfin with 8TB.... Don't get me wrong I want more and will eventually figure out how to do it cheaper but that's so impressive
The cheaper way is to either use shucked EasyStores when they're on sale or to buy them from ServerPartsDeals or whatever the site is called.
I got some 18TB drives for $200 from them. With EasyStores, 14TB drives are about the same price. The 18TB drives are refurbed and come with a shorter warranty, but you have to be rather careful with the EasyStores to maintain the warranty and you'll still likely lose it.
Just want you to know that you have just made my life better and now I have a dangerous game ahead of me to not buy so many of these drives and completely lose all my money
