And if you read all teh 'tuning' guides it tells you to turn Readyboost off.............

All its doing is using it as a slightly faster swap file, nothing more. Its still not "System RAM" as its a magnitude of speed slower and in some cases may actually slow things down as windows will have to contend with two swap systems. It tries to use this as its primary swap but then has to do a full swap out to disk when it runs out on the mem stick. Its better to take the initial hit if its going to swap.

I'd advise to go no where near it.
