Turn a USB Flash Drive into Extra Virtual RAM

Use pen drive as RAM in Windows

For Windows XP, you need to use programs like ebooster. For Windows Vista and above (Vista, Windows 7, 8 and 10), you can use the inbuilt ReadyBoost feature.

When you insert your pen drive into the computer, you’ll see an AutoPlay dialog box if you have not disabled AutoPlay.

Just click on the

Just click on the “Speed up my system” button and windows will start a series of tests to check if your drive is capable of being added as a RAM extension. Your pen drive needs to have –

  • At least 256MB in size, with at least 64KB of free space.
  • At least a 2.5MB/sec throughput for 4KB random reads.
  • At least a 1.75MB/sec throughput for 1MB random writes.

If these specifications look alien code to you, don’t worry – just use a USB 2 or higher pen drive and you will be fine.

If the device is compatible, you can select the “Use This Device” or the “Dedicate This Device to ReadyBoost” option to enable ReadyBoost and specify how much space you want to make available to the disk cache. Using the “Dedicate this device” is recommended to avoid accidental deletion of anything in the RAM portion of the pen drive.

Even if you have disabled AutoPlay, you can access

Even if you have disabled AutoPlay, you can access ReadyBoost from the right click context menu of your USB drive.

A cool feature of ReadyBoost is that all the data written to the pen drive is also mirrored on to the hard disk as well. That means even if you accidentally remove the pen drive, Windows will just continue with the data from your hard-disk. Although this will make the computer slower, it makes sure your computer doesn’t hang up on you.

Also, the cache data written to your pen drive is encrypted using the AES 128 standard. So you don’t have to worry about someone stealing any data from the cache written into your pen drive.

Step 5: Click Apply and OK button to save the changes.

Note: If you don’t want to use this ReadyBoost USB any more, just check Do not use this device and save the change.

After that, you can restart your Windows to take effect the changes.

Great way to make use of all those Flash drives that everyone has lying around.
