Server 2019: Poor write performance on S2D two node cluster
Hi ,
Your nodes don’t comply with S2D requirements. Additionally, I would not recommend to measure performance by windows file copying, you’ll find arguments here:

Better use DiskSPD from MS.
Regarding the storage solution, you can look at virtual SAN vendors. I have a good experience of using Starwind vSAN for 2 servers cluster. The performance is better and no problem with configuration. You can find guide here:

- Thanks! I tried to use DiskSPD and it works good and it seems simulates workload quite near to real world.
