Do you use AAM?

Do you guys use AAM on your HDD?

I have

1x 320G hitachi
2x 1TB hitachi
1 x 2TB hitachi

I set my AAM to quiet mode. Seek noise is a lot quieter.

transfer speed is about the same but seek time is increase by 3-5ms according to hddtune.

Starting up time of Linux is much longer when AAM is enable.

I prefer fast seek time ,so don't use AAM
