NVMe Performance

Hi Guys.

I just did a run with Crystal Disk Mark, the first in ages and this is what I got.



The first one is the one I just did. What I'm really interested in is the 4Kb test on the second row compared with the two older runs. Thats an incredible difference. I wonder if its a newer driver thats making the difference. The older tests are a year or more old.

That's some fast speed on the read and writes. Are you also running the latest BIOS?

Yes I am.

Crystal Disk Mark was never good with SSD drives. This one AS SSD Benchmark 2.0.6485 Download - TechSpot and Samsung Magician are more valuable.

Why such a difference?

Asus Realbench:

Check drivers for disk, chipset and AHCI, update may have changed them.

I use these commands to check disk performance:

Code:

winsat disk -seq -read -seqsize 65536 -drive c

Code:

winsat disk -seq -write -seqsize 65536 -drive c

I updated my BIOS to the latest one yesterday and then clean installed 1803. The BIOS update mentioned improved performance.

I think the results speak for themselves.
