To use ReadyBoost

ReadyBoost lets you use a removable drive, like a USB flash drive, to improve your PC’s performance without opening your PC and adding more memory (RAM). To use ReadyBoost, you’ll need a USB flash drive or a memory card that has at least 500 MB free and a high data transfer rate. For more detail about ReadyBoost, click here

If Windows is installed on a solid state drive (SSD), ReadyBoost can’t be used because the SSD drive is already fast and you won’t get better performance by using ReadyBoost.

Insert the USB flash drive into a USB port on your PC.
On the taskbar, select File Explorer.
Press and hold (or right-click) the USB flash drive (or SD card if you used one instead), then select Properties.
Select the ReadyBoosttab, then select Use this device.
Windows determines if the device can use ReadyBoost. If it can’t, a message appears to let you know.
After Windows determines how much free space to use to optimize memory, select OK to reserve this space, so ReadyBoost can use it.
