Currently using a 120Gb OCZ Arc 100. I couldn't say anything about its performance all I know is my PC boots faster, games loads quicker and tranfer rates are much better. But 120Gb sure is not enough. Looking forward upgrading to a higher capacity and found this deal https://www.amazon.com/s?me=A2YQSLQD...qid=1531736318 I mean it's the cheapest I can find. Gonna make the 120Gb as drive for OS and the 320Gb for games. Would like to hear your thoughts. Thanks!
