    write performance of NVMe PCIe 750 SSD 400G using fio under Linux

    KJY

      I want IOPS result using fio.

      I read the

      Anyone measured the performance of NVMe PCIe 750 SSD using fio under Linux?

       

      so I edit fio parameter

      fio write parameter

      [global]

      name=fioTestNVME

      filename=/dev/nvme0n1

      ioengine=libaio

      direct=1

      bs=4k

      randrepeat=0

      rw=randwrite

      iodepth=32

      numjobs=4

      norandommap

      group_reporting

      [write]

      runtime=600

      my using command is ' fio "parameter.fio" --output fsfio220w '

       

      I expect result in 인텔® SSD 750 시리즈(400GB, 1/2 높이 PCIe 3.0, 20nm, MLC)

      'read' result is good but 'write' result fall short of one´s expectations

      'write' result in file

       

      what's the matter?

      Is the parameter wrong?

       

      please answer me this result's cause or right parameters
