Storage Replica Async Performance
Should Storage Replica in async replication mode impact write performance? All of my testing has shown that it does (I am using dedicated data and log NVMe drives). In sync mode write performance is...
If you enable consistency groups, it may decrease replication and write Input/Output performance.
The best practice at this case is maintain as few disks as possible in same replication group. 2:1 or 3:1 (data disks : SR log disk) it's a good ratio.
