Know your I/O, by someone else

Today I ran into another post that goes into a practical example of diagnosing I/O problems on a linux host. It includes actual math, unlike what I did earlier.

The author also included a series of links at the bottom of the post for 'further reading' about storage issues. Including a series of articles much like the one I just got done with, but with more of a virtualization point of view than I had.
