Ejemplo:
diskspd.exe –c50G -d300 -r -w40 -t8 -o32 -b64K -Sh -L E:\diskpsdtmp.dat > DiskSpeedResults.txt

• -c50G – file size 50 GB (it is better to use a large file size so that it does not fit in the cache of the storage controller);
• -d300 – test duration in seconds;
• -r – random read/write operations (if you need to test sequential access, use –s);
• -t8 – number of threads;
• -w40 – ratio of write to read operations 40%/60%;
• -o32 — queue length;
• -b64K — block size;
• -Sh — do not use cache;
• -L — measure latency;
• E:\diskpsdtmp.dat – test file path.
