Storage Spaces Direct: performance tests between 2-Way Mirroring and Nested Resiliency

Microsoft has released Windows Server 2019 with a new resiliency mode called nested resiliency. This mode enables to handle two failures in a two-node S2D cluster. Nested Resiliency comes in two flavors: nested two-way mirroring and nested mirror-accelerated parity. I’m certain that two-way mirroring is faster than nested mirror-accelerated parity but the first one provides only 25% of usable capacity ...
