    Try command below, for SSD speed should be more than 200MB/s:
    Code:
    dd if=/dev/zero of=iotest bs=64k count=16k conv=fdatasync && rm -rf iotest

    Ok great :)

    How long does it takes about for this to finish?

    Code:
    dd if=/dev/zero of=iotest bs=64k count=16k conv=fdatasync && rm -rf iotest
    And if the disk is sata and not ssd which command can i use?

    Thanks

    you run command from the disk partition you want to test to test the particular disk you want

    as to time, varies depending on performance
