Does GDS slows my hard disk?

I've a encountred a strange problems that when Google Desktop Search is running on my PC (which it almost always is), my hard disk's read speed is about 1/6th of the normal speed. I'll contact google to see if this is a known issue. I'm using several HD benchmark tools to test the speed, most notably Simpli Software's Hd Tach.

Here are screenshots of my disk's speed with and without GDS running.
