If I am correct, then the HDD on this lappy might be 5400RPM (revolutions per minute). Right now, almost all new laptops have 7200RPM. this is faster. But it is SATA. XBRITE-FullHD™ : 1920 x 1080 resolution (1080p) XBRITE-ECO™ : 1280 x 800 resolution (~720p) Also, I hope it has BR burner (not just player)...
