Dedicated SSD for games

i already have an ssd for my OS and its kinda small, i use it moslty for the OS and some programs. now im thinking about gettng another ssd for games only i was think of a 250-ish gig ssd for all my games, i dont really want a huge ssd cuz i will start filling it with useless things that i wont play often, im looking for some tips and ideas on what i am thinking, so far my idea is this for my drives:

1st drive: 120gb ssd for OS and other programs

2nd drive: 1.5 tb HDD for movies,music,document, etc

3rd drive: 25-ish gb ssd for games and steam

I would either get one of each of these:

Or just one of these:
