Windows Vista Service Details
This is that fancy new Vista feature that enables you to use USB Flash Drives as a hard drive cache, and not extra memory as some people have stated. If you pull the drive out in the middle of using it, the computer will not crash, as no unique data is present on the drive. Check back soon for a benchmark of how this ends up performing, after I get a card that is fast enough to allow it. A large portion of existing flash drives are NOT fast enough to support this feature, meaning using your flash drive will actually be slower than just grabbing them from the hard drive. Windows will tell you when this is the case. So, before running out and buying a flash drive, do some research on random access speeds and flash drives to make sure your 200x ~14MB/s flash drive is actually worth anything or if its just marketing hype. The numbers they give are for sequential reads, not random.
Provides support for improving system performance using ReadyBoost.
Consequences of Stopping:
If you disable it control panel won't work any more.. Well, maybe if you disable readyboost, then kill the service, it will recover. I have not looked into it yet.
All services listed in 'Required For' will be unable to function
