Quick and Dirty I/O Benchmark for Linux
2016 June 25

A quick and dirty benchmark to see how much I/O bandwidth your machine has is as follows. I created this because I just learned about pv, and I’m sure its been done before.

cat /dev/zero | pv > /dev/null

This tests to see how fast the pipes system works on your specific machine by using the infinite zeros device and counting how many bytes it transfers per second to the null device. This does not actually write to your hard drive.

My results were as follows on my various machines.
