Looks good. Can you run hdparm -I /dev/hda?

And there please have a look at the line with acoustic mgmt:

Recommended acoustic management value: 128, current value: 128

(this line is from my laptop).

Run it on the faster node and compare those. Maybe it's ust that somehow 
acoustic mgmt is enabled on one and not on the other.
