Yes it does mean it.
See other posting in this thread.
Assuming the drive reads 112MB, this takes 112MB/11.2MB/s = 10secs.
This data will be transfered via PIO in several chunks which need altogether
112MB/16.7MB/s = 6.7s. Now, during PIOing data, the CPU can't do anything
else, so CPU consumed is 6.7s/10s ~= 2/3. qed.
