Windows ReadyBoost allows you to add a non-volatile USB 2.0 flash memory drive to improve memory performance on systems that have less than 1GB of memory. This is is a great feature to use if you have a computer that is difficult to upgrade the random access memory (RAM) like a the new and very popular MINI computers on the market.
Windows 7 ReadyBoost is very easy to use. Once you add a USB flash drive to your computer Windows 7 checks to see if the performance is fast enough to work with Windows ReadyBoost. If so, you are asked if you would like to use this drive to speed up Windows 7 system performance. You can choose to use all of the Universal Serial Bus (USB) drive or part of it.
