Some time ago, I published here comparison of SQL Server Failover Cluster Instances (FCI) and SQL Server Basic Availability (BAG) performance while having them run on top of StarWind Virtual SAN. Today, I measure SQL Server BAG performance on Storage Spaces. The next part sheds light on SQL Server FCI performance on S2D. Can I squeeze two times more TPM out of SQL Server FCI on S2D than SQL Server BAG can provide on Storage Spaces?
