I was able to get a DroboPro on eBay in 2015 (I think) with 11Tb in it already for $350. It's a decent bit of money, but not as much as many people generally assume. Since then, two drives have died and I have neared max capacity once, resulting in three new drive purchases in five years, which is about what I'd expect given the expected life span for the drives (I budget for one new drive a year). I always buy the cheapest per Tb drive and I generally try to go as long as possible before upgrading since capacities and price are always dropping. With the way drives are going right now, I should be able to easily stay ahead in terms of capacity. I generally don't compress for anything I really care about (or if I just want to skip a step), but will often go to a modest compression for everything else. So far, it's been great. There's the Harmy's Despecialized Editions, Project 4k77, another random 35mm scan, and a few others. Harmy's was the big one for close to a decade before these 35mm films were found. That one had people going so far as to repaint matte paintings. Again, they're transparent about their process, so if you disagree with it, you can decide not to watch that version or try to help find a better source so they don't have to go that route, or just try to convince them why that decision isn't as good as some alternative.
