You may already have done so but you can check IO-utilization of the 
devices with the flag "-x" to "iostat" like for example "iostat -x 2" over 
a two second interval. Check percentage utilization in the "%util" column 
to the right. If you are closer to 100 than 0 then they (the disk 
subsystem) might actually be busy.
