I’d like to express my disappointment in WD marketing/advertising of the 4TB WD My Cloud Mirror external storage device. On the WD product spec page WD does not specify the size of the drives that come with the unit. WD tells us the capacity of the unit but not the size of each drive, the speed of the drive, if the capacity you are quoting is with RAID 1 or RAID 0.
I bought the 4TB My Cloud Mirror. My expectation was that I bought 2 qty 4TB drives that mirror each other within the unit. If one drives dies the other has a mirror back up of it. I received 4TB My Cloud Mirror in the mail and opened to find out that I have 2 qty 2TB drives set up for RAID 1. So I have a 2TB Cloud Mirror, not a 4TB Cloud Mirror as marketed by WD.
WD please specify in the product specs exactly what the unit drives are, are they 5400 rpm or 7200? Please do not make it vague by telling us capacity and not specifying the type of capacity.
I will be sure to tell everyone with the frustration I experienced trying to understand what I was purchasing from WD. I uasually build my own storage but I wanted to get something easy for back up only. I feel duped by WD and I would never buy another WD all in one unit again.
