Ps3 – spec difference between the PS3 slim models

It really depends on your usage. Many PS3 games have a forced "install" where sometimes multiple gigabytes of data are copied to HD storage for fast in-game reads (looking at you Metal Gear Solid 4). As well, some games on PSN can be quite large, not to mention that PSN has a few full-fledged retail PS3 games available for download, as well as high def movies.

Having said all that, it looks like Rock Band song downloads are around thirty megabytes a piece, giving you space for ~500 songs on the 120gb model.

Also, the commenter above is correct, the PS3 (including the slim) can be upgraded with any 2.5 inch HD in the future if you run out of space.

AFAIK it's the same with better graphics, picture gallery and the ability to share fishing minigames with friends.

EDIT: Someone made a list of the differences:

• The title screen is different

• Some slowdown before attacks until you've had the game on for a bit.

• The electric room with the machine soldier in the "Factory" has permanent slowdown which actually makes it a lot easier to do that sequence of lever presses. I think this was done on purpose because there's no other parts like it in the game.

• Hachio's name is "Haochi"

• Heavy Dagger is now more accurately called "Frost Dagger."

• The room with the block puzzle in angel tower has one of the passages decreased in width and you can't get into random battles to teleport to the top to skip the puzzle.

• Stallion's color scheme is completely different. He is Brown, white, and yellow if I recall.

• "Utmost attack" had its name changed to "Vacuum Wave". I think it is because Stallion was supposed to look like "Ultraman", a Japanese hero. Utmost attack must have been one of his techniques?"

• In the Desert, getting into random encounters does not turn Ryu in a random direction. Turning right once, then walking straight until you reach Manmo still works thankfully.

• Dupe glitch does not work anymore.

• The Holy Mantle seems to work better. If you walk perfectly straight, you will go a while without fighting. Take a single turn, and it's battle time though. I remember it doing absolutely nothing.

• Finally, all of the music has added instruments which in my opinion make the music in the game a LOT better. I have never heard those extra sounds even on my I-pod. When I play my PSP on TV, you can still hear the new sounds. I wonder if the music had some sort of error in all of the tracks to begin with? Every song I can think of has something new in it.
