Hey guys, I currently have an old first hand drobo that I bought second hand last year. I'm currently interested in buying a TB HD option and right now all there really is that is comparable to the Drobo is the Pegasus. But what I love about the Drobo is how versatile it is. I can swap in any size drive in any order I want. I know the Raid in the Pegasus isn't quite as easy and I wanted to know the limitations. How does that work compared the Drobo, what are the pros and cons.
