    # Raspberry Pi HDD/SDD benchmark script.
    #
    # A script I use to automate the running and reporting of benchmarks I compile
    # for my YouTube channel.
    #
    # Usage:
    # # Run it locally (overriding mount path and test size).
    # $ sudo MOUNT_PATH=/mnt/sda1 TEST_SIZE=1g ./disk-benchmark.sh
    #
    # # Run it straight from GitHub (with default options).
    # $ curl https://raw.githubusercontent.com/geerlingguy/pi-cluster/master/benchmarks/disk-benchmark.sh | sudo bash
    #
