268w ago - MTV have found out that some Blu-ray games require installs to the hard drive because Blu-ray drives can only read at one speed.
"When this is combined 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."
To quote: 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.
Installations are a way around this issue.
When a publisher asks you to install a game on PS3, it's because they're moving some of the disc data to an area of your console that has much faster read access: the hard drive. You get vastly reduced loading times, but have to sit through an installation.

i like games that install the entire game to HD and never load data off the bluray disc once the the game is booted... like gundam crossfire for example.
now i can also see how having the option to install data is better than being forced into it. having that large install data on the bluray disc kinda acts like padding and helps speed up load times off the disc.
I didn't mind the long install at all. As long as it cuts down loading time while i'm playing, a 20 min install once during the beginning is well worth. It'll give you time to enjoy the weather outside before you lock yourself in for a gaming marathon
I believe guys at Capcom just do not know how to perform fast copying of data from BD to HDD. Both Heavenly Sword and Unreal Tournament 3 install something like 2GB of game data to the hard drive which is nearly half size of DMC4's setup while those game require much less time (than 10 minutes) for the installation process (compare to 21 minutes of installation procedure in DMC4 to copy 4.5GB).
