  • How To Benchmark Disk I/O
    08/14/2014 12:24PM

    Here is a quick snipped on how to benchmark Disk I/O with dd.

    $ time sh -c "dd if=/dev/zero of=/home/rchapin/test.zeros bs=1024k count=10000 && sync"

    10000+0 records in
    10000+0 records out
    10485760000 bytes (10 GB) copied, 81.4124 s, 129 MB/s

    real    1m21.950s
    user    0m0.810s
    sys     0m5.474s


    Will do a write test of 10GB.

    You can do a similar test and read from that file generated and write to another file or /dev/null to get an idea of the read speeds.

    See the this link for more information.
