S2D performance: 2-way mirror vs 3-way mirror
How many mirrors? Over the past few months we’ve deployed several Storage Spaces Direct solutions, and one question that seems to pop up is the expected performance difference for a 2-way mirror vs a 3-way mirror. The obvious answer is a 2-way will out-perform a 3-way, but by how much? I won’t go into the resiliency or design decisions or when either option is preferred, this is purely from a performance based perspective.
