SuperFetch and ReadyBoost are the two famous features introduced with Windows Vista OS. However, as Vista fails to leave strong remarks of their success & functionality, these features aren't become in light enough to catch the audience attention. However, the same feature has been equipped in Windows 8, the latest operating system from Microsoft introduced at 26 October 2012.
ReadyBoost is used to speed up your PC specially when you've limited capacities RAM and don't want to purchase additional RAM. As soon as you insert any USB stick or memory cards to your PC, a pop up dialog box will open with the option to use the drive as an extra RAM to have higher system performance. By default, you'll get the screen as shown in image below and the option will be Speed up my system.

Once you click on the option at dialog box Speed up my system, at the next screen you'll able to set the amount of USB storage space that you want to let system use for improving performance. Don't forget to click on the radio box stating Use this device before assigning the space to improve system speed. Remember, you'll not e able to use reserved space for saving documents or for any other activities.

How ReadyBoost works?
Lets digg into little deeper to find out how ReadyBoost exactly works in conjunction with your system memory. SuperFetch, introduced with Windows vista changes the way how open programs and files were handled in memory RAM. SuperFetch loads a copy of file information and libraries into RAM and use it access directly instead of looking into hard disk drive, which may eventually takes longer time. SuperFetch works concurrently with ReadyBoost when USB device is used and Windows will place the SuperFetch data into ReadyBoost drive. This will free up some more system memory and ultimately, improves the PC speed.
Experts will not recommend using ReadyBoost specially, when you've more than enough RAM capacity say 2 or 4 GB. Though, if your system faces extremely low operation speed due to shortage of RAM capacity (merely 512 MB or below), you should try this features if that can helps you to optimize your system performance.
