I don't need more than a 160gb Caviar Blue but it only has an 8mb cache, while the 500gb Blue has 16mb cache. I also found a really good deal on a 1tb Black w/32mb cache and a 5 yr warranty vs 3. Would I see a difference while changing or loading maps during a game like Call of Duty World at War?
The black will be faster for loading maps during call of duty, yes. The blue will put out a little less heat and a little less noise. Most gamers seem to be going with the blacks or the Samsung f3 spinpoint.
