I watched about 45 seconds of that video before I wanted to punch that guy in the face...

That said, I've heard mixed reviews about Drobos. One of the biggest complaints I've heard is that Drobo uses a proprietary read/write system, so in the event of a failure of the Drobo (not just one of the drives, but the unit itself), your data is basically held hostage until you find a Drobo-based solution. You can't just pop the drives into another enclosure and copy the data over, so you're forced to use another Drobo in order to retrieve your stuff. I have no personal experience with them, but I've considered giving it a shot as a working drive...but definitely not as a backup solution.

Not to mention it's bloody expensive, especially when you add a handful of decent drives to stick in it!

I have one of these, this is actually the Drobo 5D. It's working well, and fast too - ex/ 230MB/sec sustained write to my iMac internal SSD. I have 5x4TB drives plus a 128GB mSata SSD drive for cache in the unit.
