Three-way mirror (8 disks): Maximum 2 disks can fail. Parity (12 disks): Maximum 1 disk can fail. These configurations ensure that data availability meets the technical requirements for fault tolerance and resilience in Storage Spaces Direct (S2D).

By default, when you specify Mirror, Storage Spaces creates a two-way mirror. When you specify Parity, Storage Spaces creates a single-parity space. To create a three-way mirror space, specify 3 for the NumberofDataCopies parameter or 2 for the PhysicalDiskRedundancy parameter. To create a dual-parity space, specify 2 for the PhysicalDiskRedundancy parameter and Fixed provisioning for the ProvisioningType parameter. https://learn.microsoft.com/en-us/powershell/module/storage/new-storagetier?view=windowsserver2022-ps
