How many KB are in 4gb?
4 gigabytes= 4 194 304 kilobytes
Yeah I think it's plenty. You will see that each game has a certain amount of KB that it needs for saving. For example: Madden 12 requires 3,872 Kb of space. Gran Turismo requires only 256 KB of space. That's a total of 4,128 KB of space. 4GB is 4,194,304 KB of space. That's hardly a dent in the total amount of KB with the 4GB card.
