The issue arises from differences in the reading techniques of DVD and Blu-ray. By nature, the outer and inner parts of a disc move at different speeds while a disc is spinning, regardless of format (CD, DVD, Blu-ray, HD-DVD, etc.). While DVD drives can read data at those differing speeds, Blu-ray reads at one speed. Combine that with the extremely large size of Blu-ray discs, and simply dumping existing DVD data onto a Blu-ray disc will inevitably result in longer load times.

He would seems to be saying the load time would not be the same.

 


 If your playing a game with a small amount of data (1-2 gig), that's true. If you need to pull more then that off the DVD at a fast rate, then the BD will start to become faster.

Also, The BD gives you more options, because it holds so much. Let's take Oblivion for example.

It was made with the PC in mind. With the PC, you just install the game and go, who cares how it's stuck on the DVD. With the 360 version, they took a lot of time organizing the data to put the stuff that needs to load often in the fast part of the disk. This helped somewhat, but compared to the PC version, load times sucked.

Along came the PS3, and they needed to implement a different kind optimization. What they did for the PS3 version, is stuck the data on the disk in more then one place. I am not sure what structure they used, but for the sake of argument, let's say they copied every texture a zone needed into it's on area. That way when the zone loaded, you didn't need to move the head as much. Your transfer rate was slow, but you had a lot less seeks. You could do this sort of thing because the disk was so big.

So, Bethesda took two approaches, and optimized each media to the strengths of each system, and what they ended up with was much faster load times on the PS3 (and the PS3 version had sharper textures, so possibly more data to load).

So yes, "simply" dumping the data from a DVD to a BD could give you slower load times, but taking the time to do it right is another matter all together :)
