Both are the same spec, 1TB, SATA3, etc. except the Black has 64MB Cache and the Blue 32MB. Was wondering, is it worth an extra £14 for Black, or is the money and apparently extra noise it makes not worth the performance boost? From what I've heard the Black is noisier, and there is only a small difference between it and a Blue.
The Blue is okay for storing games. The Black is a bit faster and would yield slightly faster loading times. It comes down to whether you think spending the extra money for the Black is worth shaving off maybe a second off of your game loading times.
