It turns out that my Seagate 7200rpm 3TB hard drive (pulled from an external case) is the loudest part of my build. I unplugged it and the difference was noticeable but I still need the storage. I'd like to go with a minimum of 2TB but I think nowadays I might as well get 4TB if the qualities are the same. Performance wise, I can let that go since it's just my storage, downloads and torrenting drive. Although when I seed for torrents, it's usually about 5-8 torrents at a time, does 7200rpm relate to that at all?
