360 DVD data limit is 6.8 GB

I find it amusing that some people are arguing that seek times are not important for games stored on optical discs. DVD and Blu-Ray are *primarily* designed to stream data, i.e. - music and movies when are for the *most* part read in a linear fashion. That's why those formats use a large spiral track instead of the concentric tracks and sectors employed by hard drives and diskettes. Hard drives and diskettes are designed for random access, i.e. - programs and separate data files read in a NON-linear fashion.

So what does this tell us? That seek times are VERY important when playing a game that is stored primarily on a DVD or Blu-Ray disc, because the data will to a large degree NOT be accessed in a linear fashion. This is why Oblivion on a DVD has one copy of each data file but on Blu-Ray has several copies of each file placed strategically on the disc... according to Bethesda, the random access times on Blu-Ray were NOT SUFFICIENT to provide acceptable performance:

Sorry with all the trolling I overlooked your actual input.

Of course seektimes and layer switch times are important, like I said so within this thread and commented on to the best of my ability.

Regarding the Bethesda comment:

"Bethesda's Pete Hines also commented that recent reports of data duplication on the PS3 Oblivion disc have been exaggerated, and this technique isn't different from the similar strategy that was employed in the creation of the Xbox 360 game last year."

But this strategy IMO makes more sense on Blu-Ray as you have lots of available space to take advantage of.
