I was reading about these new drives and from what i have heard they have 5 platters. Meaning they are hotter and less reliable than 3 platter drives. Seagate are planning a 3 platter drive as soon as possible but Hitachi has beaten samsung the ones who created the first 1gb drive to the 1tb mark :).
