I did that with this giant server I have, but I hate running that thing. This computer I'm using now is honestly a pretty small, proprietary computer and it has no extra headers, it's pretty packed inside. I will be testing unraid after i'm done with OMV. Thanks for your help and suggestions.
Having a normal HBA would have made my choices a lot easier. Dealing with the DAS complicated it but everyone was pretty helpeful so I think I'm on the right track now.
The DAS seems limiting because it's USB. I'm limited on speed, and configuration. It works fine for what it is but it's basically just a giant USB drive.
I purchased the TR004 because it was cheap and I needed storage. I don't know what I would have done differently but I feel as though I'm limited by this device instead of enhanced.
A normal HBA/Controller with attached drives in a server would be my ideal I guess. Not possible at this time so I'm working with what I have!
