Have both a Drobo S and the new 5D. Using thunderbolt via the 5D and it is significantly faster. Got the "S" model when it came out, good unit no real problems, just plain works for what I want it for. No special effort, want more space, take out a small drive and put in a bigger one. It does the rest in the background and while that's happening you can still use it to access all your files. Like most products, read enough and you will find diverging opinions to the point of making your head spin. At the end, decide on what you want and how you want to deal with it in your daily workflow and go with it. All products mentioned up to this point can do the job.
