ReadyBoost is a new disk caching technology included in Windows Vista, Windows 7, Windows 8 and Windows 10 that uses flash memory to boost your system performance. It can use any form of flash memory such as a USB drive, SD card or CompactFlash.

ReadyBoost functions as a complement for SuperFetch, giving SuperFetch another place to cache data. SuperFetch is a technology included in Windows Vista which prioritizes the programs you are currently using over background tasks and adapts to the way you work. This technology tracks your computer usage behavior and intelligently preloads applications into memory. This helps improving the general performance of your system and the loading times of your core applications. While SuperFetch loads by default all the necessary files into the main memory, ReadyBoost complements it by loading data into alternate storage devices such as USB flash memory sticks.

While the USB flash drives are not as fast as the main memory, they can be faster than a hard disk drive and enabling ReadyBoost can free up some of the main memory which could be used for other tasks and applications.
