Vista has a feature called ReadyBoost which can speed up the operating system by turning a flash memory drive into additional memory. Plug the drive into a spare USB port (or SD memory card) and select ‘speed up my system’. You can set how much memory to assign to it – the more the better, it will however reduce the amount of space available for storage.
You can also give it more boost by scaling down the fancy visuals. Click Start right click Computer and then click Properties. Click Advanced System Settings and then click the Advanced tab. Under Performance, click Settings. You can either choose ‘Adjust for best performance’ or deselect any options you don’t require.
