PC World went to task on checking out the claims of super speediness when their Vista OS is coupled with a ReadyBoost drive. The marketing rhetoric all says instant “Boost” but PC World’s stop watch says maybe a soft shove at most…

We learned that ReadyBoost does shorten the time it takes to load frequently used programs–but not by much. The Lexar drive cut application load times by an average of 6 percent on our notebook and desktop PCs. Overall, we clocked launch-speed improvements of 4 to 6 percent. Without a stopwatch, you likely wouldn’t notice the increase.
