Ok so basically i have a notebook with a 500gb hdd with 5400rpm. My dilema is what should i fit in it, a new hdd with 7200rpm and a ssd with 120gb or a sshd with 5200rpm? Which one is faster? I mention that now i have very big problems with loading anything, even when i try to open a folder it lags for about 5 seconds. I want to improve the quality in booting and playing a game (csgo, which is not that demanding for resources). So, where should i focus my attention? On the combo ssd+hdd or sshd?
