I'm going to buck the nerds and say I wish Drobo was back. I love my 5N, but had to retire it as it began to develop Type B Sudden Drobo Death Syndrome* and switch out to QNAP.

It was simple, it just worked, and I didn't have to think about it.

* TB SDDS - a multi-type phenomenon of Drobo units suddenly failing. There were three 'types' of SDDS I and a colleague discovered - "Type A" power management IC failures, "Type B" unexplainable lockups and catatonia, and "Type C" failed batteries. Type B units' SOCs have power and clock go in and nothing going out.
