@TinkerToyTech, I don't think dual parity is really the best option for me, I'm not currently looking for a ton of extra storage (I have 4 HDDs and 3 SSDs I plan on putting in it to start), I just need the storage I do want to be network available and this is probably the cheaper option. By the time I'm at the point of going to 2 parity drives I'll likely have the money to buy 2 separate systems, one NAS and one gaming PC.
@bjp999 I don't plan on using 8TB drives (I have 4 6TB drives right now), but for emergency backups, I plan on using a small application I wrote to back stuff up to Amazon Glacier. on a schedule. Maybe not perfect, but it will work for me.
On another topic, I do have a question about the compatibility of a piece of hardware I was looking at. Maybe this is better suited for the hardware section, but to test everything out I was looking at something like the Thermaltake BlacX (http://www.bestbuy.ca/en-ca/product/thermaltake-thermaltake-blacx-usb-3-0-duet-hdd-docking-station-st0014u-c/10528502.aspx?) to use in testing unRAID out. I can find a use for this after, but it would be a good piece to use to test until I know this is what I really want and then I can spend on getting a bigger chassis and upgrading other hardware.
