 blktrace is a command that generates traces of the i/o 
 traffic on block devices such as hard drives.

 seekwatcher generates graphs from blktrace runs to help 
 visualize IO patterns and performance. It can plot multiple 
 blktrace runs together, making it easy to compare the differences 
 between different benchmark runs.

 Ed will show us how to install and use these cool tools.
