ReadyBoost can speed up your computer by using storage space on most USB flash drives and flash memory cards.

In the Autoplay dialog box, under General options, click Speed up my system.
In the Properties dialog box, click the ReadyBoost tab, and then do one of the following:
To turn ReadyBoost off, click Do not use this device.
To use the maximum available space on the flash drive or memory card for ReadyBoost , click Dedicate this device to ReadyBoost. Windows will leave any files already stored on the device, but it'll use the rest to boost your system speed.
To use less than the maximum available space on the device for ReadyBoost , click Use this device, and then move the slider to choose the amount of available space on the device you want to use.
If AutoPlay doesn't open, it might be disabled. For more information, see Troubleshoot AutoPlay problems.
For ReadyBoost to effectively speed up your computer, the flash drive or memory card should have at least 1 gigabyte (GB) of available space. If your drive or card doesn't have enough available space for ReadyBoost , you'll see a message telling you to free some space on it. For best results, use a flash drive or flash memory card with at least double the amount of available space as the amount of memory (RAM) in your computer.
