Ps3 slim 12 GB worth it!

Hey im thinking of buying a used slim version and the seller texted me saying its only 12gbs. I only care about playing games through disks, no digital content. I have Mgs4, mirror’s edge, CoD black ops and MW2, GTA stuff like that. Also for dvds and blu rays obviously. I dont want the hassle of putting another drive in it tbh. Will it suffice?
