How To Speed Up Windows Using ReadyBoost


Windows 10 is one of the most optimized versions of the Windows OS which runs great enough for low-end PCs as well. But on some occasions like running a file which requires optimal performance from your CPU and GPU as well, one may notice certain hiccups and lag. It is at this time that we think of increasing our PC’s specs like bumping of the RAM or using a more powerful chip but one thing that bothers is the expenses that need to be incurred to get these things done. So, if you are one of them who is troubled by the lag and underpowered performance of your system and at the same time is not able to bear the expenses of new components, this article is for you.

The technique that we are going to implement is called ReadyBoost. It was first announced during the release of Windows Vista, back in 2007. It was essentially a disk caching feature that was introduced to make Windows Vista snappier. 10 years down the lane, it made its way through all the iterations of Windows and is present in Windows 10 as well.

What is ReadyBoost?

ReadyBoost utilizes a service called SuperFetch. SuperFetch uses an algorithm that determines which files should be stored in the cache. The cache can include system files, application files, and user documents. Now when those files are needed, instead of reading the files from the disk drive, they get to read from the ReadyBoost cache instead. If a file gets changed on the disk drive, it also gets changed in the cache and vice versa.

Note: The ReadyBoost feature doesn’t work if your computer is running an SSD because it’s already fast enough to outperform the USB drive.

How To Use ReadyBoost On Windows 10?

Points to Note:

  • It’s not compulsory that you have to sacrifice a complete USB drive for the feature. You can use a part of it to store the cache file and use the rest of the drive normally.
  • Windows can use up to 4GB on USB drive formatted as FAT32. The limit expands up to 32 GB in the case of NTFS formatted USB drives.
  • Using a flash drive that’s slower than your hard drive won’t speed up Windows using ReadyBoost. So, you might consider a USB 3.0 flash drive for the ReadyBoost feature.
  • If your PC has more than 8 GB of RAM, you probably don’t need the feature because RAM will have enough space to store cache.
  • The USB drives have limited read/write cycles. So, repeated use, as in the case of ReadyBoost, would reduce their life expectancy.
  • The data on the device is automatically encrypted using the Advanced Encryption Standard—AES 128. So if you lose the device, you won’t have to worry about someone getting access to data.

Steps To Use ReadyBoost On Windows 10?

  1. Install the USB flash drive in your PC.
  2. Open your “File Explorer.”
  3. Go to your “This PC” (for Win10 users) or “My Computer.”
  4. Right click on the USB drive that you want to use as your ReadyBoost device.
  5. When you right clicked on the USB drive, a popup menu should have appeared on your screen. Select “Properties” from the popup menu. A new window should be appearing on your screen.
  6. Under the “ReadyBoost” tab, select “Dedicate this device to ReadyBoost” if you won’t be using the USB drive for any other purpose. Otherwise, select “Use this device” radio button and use the slider to reserve space for the feature.
  7. Click “ok” to finish your task.

Now, Windows may take some time to analyze and configure its requirements before setting up your USB drive as a ReadyBoost drive.


ReadyBoost is not the perfect solution to the sub-par performance of your PC. You may not notice it if you have more than 4GB of RAM or an SSD. However, if you are running a PC with very low powered hardware configurations, you may see some increase in performance; but it isn’t even guaranteed in this situation.
