Windows ReadyBoost is a new functionality built into Windows Vista designed to increase the performance of your PC. Essentially, ReadyBoost can access the RAM on a USB Flash drive, provided it’s a fast USB 2.0, to speed up computer. When you remove the USB drive, the performance returns to its original state. Here’s a Microsoft blogger’s Q&A that details some of the requirements and limitations of ReadyBoost.

What does this mean to the average user? Not much, I suppose. But, for some people, who have say 512MB of RAM on the machine they plan to run Vista on, they could go out and buy a large flash drive and have the capability of a flash drive as well as the added performance of all that extra ram. Kind of neat.

According to one report, ReadyBoost was initially designed to access RAM on dormant computers within a network. No word on when this feature might actually become available.
