Mine has a Hitachi 5400RPM 80GB with 8MB Cache. The one in the review is Toshiba that has 16MB Cache. The retail price for the Toshiba one is cheaper though. In the review, the relative weakness of the DV4000 is in the screen brightness and contrast ratio. I wonder if the one they tested is with Brightview or not. Mine has brightview and it is really bright.
