  • Let’s say you want to test a drive that is mounted on /tmp… you just cd into that directory and you can use my example.

    You can use

    $> df -h or $> mount

    to check how your drive is mounted in the OS Most ”default ” installations will have 1-4 partitions and / being partition 3 or 4.

    So if you look at the mount command and / is /dev/sdX3 (where X can be a-z depending on how many drives you have connected) and no other mounts are in the output then every directory under / is on that drive… so you can run my example from your home-directory if you fancy that.


  • The cool thing about rsync is that it goes ”BRRRRRRRRR!” like a warthog… the plane… and it can saturate the receiving drive or array depending on your network and client. And getting 180 with rsync… on a SATA drive, can’t really hope for more.

    And you can run a quick n dirty test is using dd

    $> dd if=/dev/zero of=1g-testfile bs=1g count=1
