At he moment i have seagate hdd 500gb 8mb cash 5400rpm. I am upgrading my pc and i want to change the hard disk. I have two plans in my mind. First is to but buy kingston ssd 120gb and use my current hard disk, second is to buy new hdd 1tb 7200rmp 64mb cash and a 60gb ssd. On the ssd will only be OS, internet browser and maybe some games everything else will be on hdd
