This study is so cool.

A while back I wrote a simple simulation of a spinning hard disk, with the idea being you could tweak the parameters to exaggerate (eg.) track to track seeking and then work out if your filesystem/database/backup/whatever handled it well. I'm going to bookmark this page so next time I'm bored I can update the simulation to be more physically accurate. https://libguestfs.org/nbdkit-spinning-filter.1.html
