Right-click the icon for the USB drive and choose Properties. Windows
displays the Removable Disk Properties dialog box. Click the ReadyBoost tab.
Click the Speed Up My System Using Windows ReadyBoost link. Windows
displays the ReadyBoost tab of the Removable Disk Properties dialog box.
If you??™re lucky, the ReadyBoost tab will look like the one shown on the
left in Figure 1-7.
If the ReadyBoost tab looks like the one shown on the right in Figure 1-7,
bearing the message ???This device does not have the required performance
characteristics for use in speeding up your system,??? click the Test Again
button once or twice. Windows seems to find some USB devices marginally
too slow on the first or second read, but passes them on a retest. If
Windows gives you this message persistently, try a different device.
Select the Use This Device option button.
If you want to adjust the amount of space that Windows uses on the drive,
drag the Space To Reserve For System Speed slider or change the value in
the text box. Windows recommends setting ReadyBoost to a value between
1?— and 2.5?— the amount of RAM in your PC??”the higher the value, the more
performance boost you should get. For example, if your PC has 1GB RAM,
you might set anywhere from 1024MB to 2536MB of ReadyBoost memory.
The biggest ReadyBoost value you can set is 4096MB (4GB), assuming your USB memory device
is capacious enough.
