Are you talking about ReadyBoost ? If so, It's using a USB Thumb drive
as more memory for the system.
I've Installed it. But it only works with some USB Thumb drives not all.

It works, No numbers to show how much. But It's always accessing that
drive by the light flashing.
I have a 1mb being used. Out of 4 that I own only 2 would be seen to be
used. It will test it before giving the ok for it to be used. I'm trying
it to see how long it's going to last before it dies.

A friend uses a 4 gb one and tells me that he can see a big Improvement.
YMMV
