Just for completeness, windows vista will include a enhanced prefetcher called (sic) SuperFetch. The idea behind it seems to be to analyze I/O patterns and then "mirror" the most frequently used disk blocks into the USB flash drive; so if when the usb flash drive is plugged in the system will read those blocks from it as it was the hard drive the next time you run the app (http://www.windowsitpro.com/Windows/Article/ArticleID/48085/48085.html)
