Sorry I don't have any comparison charts or numbers for you. I have installed the Seagate Momentus XT in two Dell Inspiron laptops and my own Asus G73JH laptop and I've seen big improvements on speed. Instead of giving you speed charts I can use this technical description; everything is just "Snappier". It comes with a little software in which you can put certain boot files and program exe files on the SSD part to force booting and executable using the SSD. The drive is 7200rpm and has a 500GB capacity. Hope this helps.
