Right now my computer displays 1GB of RAM in use, but in reality there is 1GB in use PLUS 1GB of superfetch data.
Here's the fun part. When Windows is running a program that needs to use all RAM it can get, it doesn't take any longer to write over superfetch-cached data compared to completely unused data. There is no performance drop.
Disabling super fetch is unnecessary. If you think you are getting anything more out of your RAM for disabling it, you are wrong.
