Windows 7 has a performance feature called ReadyBoost. This feature enables the use of a USB storage device instead of the slow paging file on your hard disk when you’re low on physical memory (RAM). The logic is simple – the USB storage device is faster than your hard disk drive.
In order for ReadyBoost to work in Windows Vista, your USB storage device must meet the following requirements:
- the device with at least 2GB space is recommended.
- the device must be USB 2.0 compliant.
- the device must have a minimum read speed of 3.5 MB/s.
- the device must have a minimum write speed of 2.5 MB/s.
Follow these steps to enable ReadyBoost:
1. Plug in USB storage device.
2. Go to Computer, right-click on the removable storage device and select Properties.
3. Click on the ReadyBoost tab.
4. Select Use This Device and set the amount of space to use for the system file.
5. Click OK.
