From what I can tell the only benefit to the Drobo Ver 2 is the firewire connectivtiy. I am looking at getting a Drobo and an airport extreme. The drobo share seems to accomplish everything the airport extreme can do apart from the drobo share has firewire. Question: If I am not going to use the firewire only the USB will the drobo ver 1 connected to an airport extreme be satisfactory? any reason to get ver 2?
