Background: I have a 2TB Apple Time Capsule that I've been using to store my media. I use BitTorrent a lot, through private trackers exclusively, and I use a Netherlands-based seedbox. Recently my seedbox was upgraded from 400GB storage to 1.35TB, and I that made me download a lot more (movies and season packs of TV shows, mainly).
I filled my Time Capsule pretty fast and went looking for the next step. I decided to get a RAID array and did a few weeks of research. I didn't want to have to spend a lot of time setting up the RAID, so I looked at the sexpensive options like Drobo and ReadyNAS. I really wanted to use ZFS because that's the new hotness, but even with the easy-to-use options, it seemed like more work than I really wanted to put in.
