I am happy to announce that the fio blog has a new post. This one is a
guest post by Joel Granados on using fio to measure write amplification.
It describes using fio of course to issue write commands but also uses
the exec ioengine to launch an external script that measures device
writes. Take a look:

Feedback is welcome!
