    So there is my question: why my ssd's iops too low and why is there a discrepancy between these benchmark programs?

    SSD: 250GB A2000 PCIe NVMe SA2000M8/250G SSD
    GPU: Sapphire AMD HD 7850 1GB
    Ram: 1600mhz Gskill DDR3 CL9
    Motherboard: Asus M5A97 R2.0
    CPU: AMD FX-6200
    Psu: Thermaltake Litepower 700W
    My ssd specification: 2000mb/s read - 1100 mb/s write / 4k random iops read:150k - write:180k on the paper.

    I'm guessing the AMD FX CPU paired with the DDR3-1600 RAM is bottlenecking things.
