I wouldn't put any games on the SSD though. There's very little benefit aside from load times and a 120GB SSD can fill up easily over time depending on what you do.
STEAM, for example should be on your HDD (i.e. "E:\STEAM")
so the ez smart response where the ssd works as a cache of the hard disk (max cache memory size is 64 gb and the rest of the space can still be used as storing data ---- is there any plus in this setup ???????? but it says you have to put os on the hdd disk
