Actually, the additional installs of MSG4 overwrite part of the already made 4500MB install. This is why you have to reinstall parts when you go back to an act oyu already finished.
So no, I didn't forget it. It just takes 8 minutes to install 4500MB on a PS3. If you're using the drive optimally that is.
Really, I hardly understand why people are confused by this. It's quite simple, the PS3 has a drive which reads, on average, at 72Mbit a sec (i.e. 9MB/sec) - all Blu-ray 2x drives do this. And that fits with the time it takes for MSG4 to be installed initially. DMC4 takes 22 minutes for 4800 MB, which comes out to ~3MB/sec. Which is nowhere near the max read speed of a Blu-ray 2x drive. Capcom probably read lots of little scattered files during the install, whereas Konami probably optimized the data on the Blu-ray so it could read a few larger sequential files.
The Xbox drive is obviously faster, it reads DMC4 in ten minutes. That comes out at some 12MB/sec, but is very probably not reading single files at a time. Microsoft most likely made the installer create disc images on the harddisk since that is a very good way to keep compatibility (kind of like Deamon tools on the PC used to do). It also keeps your installer simpler, which is always good. |
This is almost exactly what is happening. They are ripping the image, saving it to the HDD and mounting it to a virtual drive when to be played. This is why the 360 installs can be optional unlike PC?PS3 install, however you will not get the same performance boost as you would from a full instalation.
For multidisc games it looks they remove duplicate information as the Lost Odesy install is supposedly only 10GB.
