discusuion is compression of video games better or not?

[jorg]

oka so the ps3 has a set read speed for games at 9mb/s know dose compression work for games the same way it dose for video's or archives were it transfer the compressed data say 15 mb when uncompress it, meaning after its off the disc and unpacked inside the console its say 40mb of data? or dose it not work that way since video games render completely in a console.
becuase i was just thinking blu-ray gives the ps3 the ability to use 50 gig of space but with only a 9mb/s data rate with compression could u not transfer more data threw compression with minimal system impact?

Had to do some EDITING there.

BD has 36Mbps data transfer rate. The drive in the PS3, and most other drive on BD players, have 2X speed.

For games, compression is a double-edged sword. You can use it to give you 50% more data but that means the user will eat up a lot more HDD space. Or you can only load the data necessary for that game level but at the cost of the speed of the load-up.

BD movie compression is not the same as data compression for games. For movies, after compression the movie is streamed out; BD-Java requires minimal computational power. For games, decompression is the first step of data collection.
