SuperFetch is a new feature in Vista that learns which applications you use most and preloads them into memory, reducing paging and load times. This is similar to the prefetch used in XP however, Microsoft has come up with a very compelx prioritization scheme that will differentiate which applications you use and when you use them.
What SuperFetch also allows you to do is insert a USB thumbdrive and use it to cache, rather than paging to the hard drive. Hard drives are much slower than flash based memory, and by doing this, there is a noticable performance boost.
