Ps4 is coming out in less than 3 weeks. I want to know what is the biggest HDD we can get that will fit in it so I can order it now and be ready to install it on my ps4 by nov 15. Most importantly, what is the height, since we already know its a 2.5" HDD. But they come in many size, such as 7mm, 9mm, 12.5, 15mm. ect. I dont think sony mention anything about its height.
