If I had a DroboPro that I filled with then approved Green drives I would be very unhappy to say the least. Not just because this change was made midstream but particularly due to the lack of an explanation. This is an extraordinary step taken by Drobo with no explanation at all.
What bothers me the most, above all else, is that it leaves the legions of DroboPro owners with green drives totally in the dark as to what, if anything, they might need to do about. Specifically the relative risks of leaving these no longer approved drives in service. There are very practical and very negative implications to the silence.
I have no skin in this particular game but I do have a V2 filled with Green drives. I could be next, and without a very detailed explanation of reasons for the policy change no one can argue that we V2 owners are not next because we know nothing; we can only speculate. Not good.
