AAM - Performance

I ahve a WD 5000 AAKS which was bloody noisy with its seeks inside s Scythe Quiet box.

Using AAM on 128 it has killed all of the noise - however i notice the nosie pretty much died at a much higher setting but i took it down to 128 for good measure

what sort of loss in performance will i see?

Seek times will take the greatest hit. Mine increased by 7ms (went from the maximum loudest setting to the minimum quietest settting).

got any cheap/free/ tools that let me test it?

is 7ms a lot?

HDTune and HDTach.

Normally the delay is around 8-9ms, so a 7ms addition essentially doubles it. Depends on your use if you notice it barely or at all though.

I am suspicious that setting AAM to quietest is causing me problems!

Since I got my WD 500GB SATA and put on AAM my PC would randomly freeze - I put this down to Windows Indexing service - which I switched off and it has helped a lot - but I wonder if it was AAM being on that caused the slowdowns in the first place?

I noticed when I put AAM on that if I lowered it halfway then the noise woudl go down the same amoutn as when I put it all the way down - will I improve performance much if I put it abck up to half rather than all the way down?
