Hard drive/8mb vs. 2 mb
In choosing between these two HD's at the same price, would I want to give up am 8mb buffer for the second one that has Fluid Dyamic Bearings, but only a 2 MB buffer? How important is the buffer?

Oh, and I would definetly go for the 8MB cache :)
And I am not sure if some HDs perform predictive caching, which means anticipating what you might need and having it ready, even if you haven't asked for it before. I think so.
