USB devices are essentially storage media, just like external and internal hard drives. RAM is used for temporary storage of data. It is built into the computer itself, which provides quick access to the information you need. Other media, including flash drives, store data permanently. Starting with Microsoft Windows Vista, the operating system contains a feature called ReadyBoost that allows USB devices such as memory sticks to be used as a way to expand memory without having to boot the computer.
Necessary
ReadyBoost requires a USB 2.0 flash drive with at least 1 GB of free disk space. Your PC should be equipped with a USB 2.0 port, preferably installed on the computer itself, rather than connected through a hub
Instructions
Step 1
Customization
To use ReadyBoost technology, connect your USB device to your computer. The autorun function brings up a menu with a drive name and a list of parameters. If the menu does not appear, you can disable autorun and re-enable it. Click on the ReadyBoost tab in the menu. If you don't need to use your device for anything other than extra memory, select "Speed up system using ReadyBoost and click OK."
Step 2
Settings
Click on the "Use this device" button. Use the slider to select how much space on the device will be used to expand storage. The menu will offer you recommendations for settings for the best performance of your PC. The choice is yours: you can accept them, or you can experiment. Click the OK button.
Step 3
You can then use the slider-icon to choose how much space on the device to assign memory; the rest will remain free for use as a warehouse. The menu will recommend drawing for best performance, although you can experiment with other settings if you wish. Click the "OK" button when you have selected a picture.
