But to add a drive I have to tear down the array and rebuild it, right? This gets impossible with the amount of data in larger arrays.
And I guess this isn't really relevant with my system, where one side of the mirror is in the HTPC, and the other is in the garage. A fire in either place would destroy all data in an odd number drive system.
