With the new Mac Pro, I'm looking for a simple jbod external solution. I've looked into Pegasus2 and Drobo and the only thing I don't like about them is that if the box dies outside of warranty, I have to buy another box to access my data. I'm also not crazy about having to use identical drives throughout those cases. I simply want something comparable to internal storage practices in the current Mac Pro (using jbod). I don't require critical access speeds -- just something comparable to what I'm used to for internal storage in my current Mac Pro. Do I need TB1, 2, or USB3? Ideally, I'd like a 4-5 bay enclosure, using jbod, where I can mix brands and speeds and when one fails, I can replace it with any drive I want. I'm also looking for a solution, where if the box fails, I can plug my drives into other units and recover the data. The one thing I love about the Drobo is that it notifies you when drives fail. Any suggestions? With the expensive Pegasus/Drobo solutions, I feel like I'm paying for a Ferrari when I'd be using it like a Honda.
