Two of the buzzwords surrounding the launch of Microsoft's Windows Vista Operating System are SuperFetch and, perhaps more prominently, ReadyBoost. Tom's Hardware Guide examines and benchmarks both of these additions to the OS to see if they actually do improve performance at all.

Vista comes with two mechanisms that effectively reduce the time required to launch popular applications: SuperFetch analyzes your behaviour and proactively puts applications into available main memory, so they can be launched quicker. Of course this requires as much main memory as possible, which is where the second feature engages: ReadyBoost allows expanding the main memory size by plugging in a USB 2.0 Flash drive. Although the data transfer performance of USB 2.0 devices cannot compete with modern hard drives, access times for Flash memory are literally nonexistent, making these devices a nice and particularly cheap choice.
