We've been using storage systems from Drobo in our shop for quite some time now. We've got the entire office wired so we can share HD video projects to any workstation. We've also been backing up files from our HD shoots with Drobo Pros. We've been quite happy with the arrangement and Drobo asked us to explain our workflow.
