How to Use Your Pen Drive as RAM in Windows 7?

Windows 7 has a feature called ReadyBoost which enables its users to use their pen drives as temporary RAM for their systems. This feature is helpful when because of any reason you need to speed up your system for short time. Instructions to do this are given below:

  1. Insert a flash drive (Pen Drive) in the USB port.
  2. Open “Computer” by clicking on “Start” button and clicking on “Computer”.
  3. Right-click on the icon of the newly inserted flash drive and select “Properties”.
  4. In the “Removable Disk Properties” page go to “ReadyBoost” tab.
  5. If you want to dedicate the entire space of your flash drive for ReadyBoost you can select the radio button that says “Dedicate this device to ReadyBoost”. Alternatively you can dedicate any specified amount of space from the flash drive for ReadyBoost. To do this  you can select “Use this device” radio button and in the text box you can specify the amount of space from the flash drive that you want Windows 7 to use as RAM.
  6. Clilck “Ok” buttons on all Windows to accept and confirm your selections and configurations.


More Info:

When ReadyBoost is enabled a file named ReadyBoost.sfcache is created. This file is compressed and encrypted so that even if any one steals the pen drive, the thief cannot read data the pen drive contains.


Do NOT pull flash drive out of USB Port while it is being used as a ReadyBoost device.

Do NOT save any data files on the flash drive when it is being used as ReadyBoost device.
