A quick way to get a speed boost is to use a USB memory drive, which adds extra memory to your computer in a similar way to adding more RAM. The drive must be larger than 256MB and conform to Windows data read/write speed requirements.
Plug it in and select the Speed up my system option from the AutoRun menu. Windows checks the drive and, if it’s suitable, you’ll see a ReadyBoost dialog box.
Tick the Dedicate this device to ReadyBoost box or select Use this device and adjust the slider to select how much free space you want to assign to ReadyBoost. The remaining space can be used for storage as normal. Click OK to finish.
