# Raspberry Pi microSD card benchmark script.
#
# A script I use to automate the running and reporting of benchmarks I compile
# for: http://www.pidramble.com/wiki/benchmarks/microsd-cards
#
# Usage:
# # Run it locally.
# $ sudo ./microsd-benchmarks.sh
#
# # Run it straight from GitHub.
# $ curl https://raw.githubusercontent.com/geerlingguy/raspberry-pi-dramble/master/setup/benchmarks/microsd-benchmarks.sh | sudo bash
#
# Another good benchmark:
# $ curl http://www.nmacleod.com/public/sdbench.sh | sudo bash
