The WD Caviar Black is slightly faster when it comes to some other things, it does have a bit higher IOPS but it will still not be very noticeable, after all it is still just a 7200RPM with a different controller and a bit more cache.
I don't really see any other points in your post, you mention longer warranty and video capture performance which you say the difference would be noticeable, which it really won't be.
