I have a strong dislike for Drobo's. They might be good consumer devices, but I inherited a company using them in the place of a proper RAID (which we are now yanking out and replacing with Promises). Biggest problem is how slow they are. The next big problem is that once at a certain capacity, terabytes of space mysteriously disappear.
