I will grab the occasional file that really interests me, but lately since I've discovered sites like Flixer or streamvaults, I will just stream the shows and movies that I'm curious about but don't really feel the need to collect.
I hoard media. I’m particular about my releases. I don’t want to stream some shady website that could disappear half way through a show.
I kept waiting to invest in more drives. Now I’m stuck with 4x4TB for the foreseeable future because replacing that raid array is brutal and even then I want to go bigger. Like the other commenter said, I’d like to be able to mirror big data sets.
