If you have a Drobo (especially an older one) and haven't yet upgraded you might want to wait.
I updated everything according to instructions and now my Drobo speed is very very slow. So much so, that I'm temprarily copying my camera photos to my desktop to process in Lightroom. I have 2T worth of photos on this device so I'm a bit worried even though all the finals and important stuff is backed up. At its current speed it would take many days, if not weeks, to get my files copied elsewhere. Sigh.
Data Robotics is working on this so I remain hopeful and patient that a solution will be found. There are lots of others in the same boat.
