Samsung 970 EVO low IOPS performance

Hi,


I recently bought this drive. I have Windows 10 on it with 335GB free. Samsung NVMe driver is installed. Newest firmware and it uses PCIe 3.0 with 4 lanes.

Data Transfer speeds are OK, but IO performance is half or lower than 30% of what others report.


For example: https://www.guru3d.com/articles_pages/samsung_970_evo_m_2_500gb_nvme_ssd_review,14.html shows 129693 IOPS but mine only does 33944 IOPS.


Samsung Magician shows only about 115000 read and 100000 write IOPS


Any idea why?
