Ah, thanks for the link. This is similar to Tixy's tool, but it focuses
on a different aspect of drive performance: While you mostly care about
seeks on hard drives, the most important performance factor on flash memory
cards is garbage collection cycles. There is some correlation between
the two, but also some significant differences.
I guess it would be possible to visualize GC in seekwatcher as well,
if anyone is motivated enough.
