E-booster

It speeds up your PC and improves application responsiveness by using flash memory and free RAM as an extra layer of performance-boosting cache for your PC. Use up to four inexpensive flash devices to speed up your system. Add more speed to your PC without any hardware upgrade!

NOTE: I recommend this to users who cannot afford to buy ram for there PC and LAPTOP. This is not a free application but it can help you when you need some extra memory for your computers.
