windows - Disk Activity? What does it mean?

I'm using this Windows Gadget for information about my hard disks. Besides available/used space, it has read and write speed. Those are pretty much self-explanatory. Then there is this "disk activity" measurement, and is a percentage indicator.


I have noticed that when it is really high, my computer gets slow, specially right after boot, when lots of programs are being started. However, many times the read/write speed indicators are quite low, and the disk activity percentage is high.


I don't think I understand well enough the concept behing this disk activity indicator, why is it in percentages, what does it mean?
