8mb vs 32mb cache plus extra storage space. That is the improvement you would get. Don't know if it would be noticeable for you. If your plan is to speed up loading times, go with a SSD instead for noticeable performance boost. But for storage upgrade plus some performance increase then go with the caviar black.
well right now my 250GB drive is getting full and i'm curious about an upgrade to a 500-750 drive
like i said my 250GB drive is fine right now and i can manage the space with being creative but if it's worth it
i'll seriously consider pulling the trigger on a black
i probably won't go the route of a SSD because they're too expensive for what you actually get out of it right now
