I am looking to build a PC in a few months, I do intend to use it for some gaming, but not very much. In fact, there is only one game I am looking to get at the moment, which is Batman: Arkham Knight? Now I've been looking at the hard drives, and I am certain I want to go with Western Digital. I was originally going to go with a 500 GB Caviar Black, but I decided to look at the 1 TB drives. I came across two that I like, but I am not sure which I should go with. I am looking at either the WD Blue WD10EZEX or the WD Black WD1003FZEX. As I understand it, they're both pretty identical - Sata 6 GB/s interface, 72000 RPM, 64 MB Cache, 1 TB platter, and such. I've read that the Caviar Black drives are typically faster, and come with a 5 year warranty compared to the 2 year warranty for the Caviar Blue, but I am not sure that it is justified to get the Black. Could someone help me dissect the key differences between these two drives, and assist me in selecting the correct one?
