Details
The performance of sequential read after random write could be dropped especially in SSDs. So sequential tests should be performed at the beginning. And the option '-h' when running diskspd.exe causes 'WRITE FUA' which is the main reason of write performance drop mostly in case of StorNVMe. So I think the option '-S' is suitable for write tests.
