Wouldn't it be great if I could just click on a file system object (like a drive in the file browser) and view a diagram of concentric circles for registers, cache, ram, io layer (disk buffers/caches), and finally the actual physical device.

The size of each circle would be relative to the avg. amount of time needed to move data to the CPU. To me this would be more intuitive than charting system data.
