The most valuable feature are the caching capabilities using the storage class memory.
Microsoft Storage Spaces Direct offers reliability with no single point of failure and impressive caching through storage class memory and flash tiering, resulting in performance three times faster than VMware. While price performance is a key benefit, optimization for mirroring and documentation needs attention. Scalability beyond two nodes is possible but requires a full cluster rebuild. Hardware compatibility certification is complex, and Microsoft's support for shared clusters has been discontinued.
