Please keep us updated. I don't know about anyone else, but I'll be following this thread like a hawk.

I haven't been able to find anything at all that is even remotely comparable to the Drobo products. The only other multi-disk systems that are even close to the DroboPro (which is what I've been looking at) are rack-mounted arrays from Promise. They don't have the user-friendliness nor auto-expansion features though.
