Nope, I was refering to the Samsung HD160JJ 160.0GB SATA drive and SP1614C 160.0GB.
I saw 18+ ms with AAM enabled and 13-14ms after it was disabled. My results varied between hosts. Once I get a motherboard replacment in from newegg, I can try it again on the HD160JJ. I know it's not the same drive as yours, but it should give you an idea.
I also had similar results with my maxtor Maxline III 300GB. The Access was terrible until I disabled AAM.
