How I see it is that the black is larger (640gig vs 500gig) larger 64mb cache, and black version is more performance and enthusiast oriented. BUT.... Average Seek Time: Black 11ms vs Average Seek Time: BLUE 8.9ms hmmmm... What would you do? Price is not much more for the black More about : 500gig blue faster specs 640gig black mosox a b G Storage December 29, 2010 6:33:24 PM The first one has only one platter with higher density.
