I work as a video editor on a Mac Pro 4,1 in FCPX. I have a huge video project coming up and will need some seriously storage. I was thinking of going for a Drobo, but just saw that the new Drobos don't come with firewire 800. Being on a older Mac Pro am I right in thinking that connecting it via the Drobo's USB 3 port to my Mac Pros USB 2 port would be a considerable slower connection than the older firewire 800 drives? If so, I would really appreciate people suggestions for a small(ish) raided (for safety) storage solution and setup. As I said i'll be editing HD video, so it has to be connected to the fastest port, or in the fastest way possible. Many thanks!!
