Using ReadyBoost

Need a cheap way to get more PC performance ?


ReadyBoost LogoReadyBoost is a feature built-in to Windows Vista and  Windows 7 and Windows 8, that enables you to use a USB drive/Memory card to give your PC a memory boost.

While it’s normally wiser to install additional memory, ReadyBoost is ideal people running older PC’s and laptops that are only capable of holding a small amount of memory – ie: Have a 1-2 GB RAM limit.

How does it work? When PC’s run low on memory (RAM) they can borrow some additional thinking space from the Hard Disk Drive – however most hard disk drives are mechanical and are slow compared to electronic memory, USB drives or Memory cards.  ReadyBoost enables your PC to use electronic media rather than mechanical hard disk space.

To start using ReadyBoost

Simply plug-in a spare (blank) USB drive in to your Computer and follow these prompts:

  • Click on ‘Computer’ and then right-click on your USB drive.
  • Now click ‘Properties’ and select the ReadyBoost tab, as shown below.

ReadyBoost Properties

  • Select ‘Dedicate this device to ReadyBoost’ and click ‘OK’.


You’re now making the most of Windows ReadyBoost features, harnessing the extra memory available to you in external USB devices to give your computer’s memory a boost and speed up its performance.

It can now borrow memory from your nominated USB drive rather than your hard drive, which is much faster.

  • Not all USB drives are capable of being used for ReadyBoost.
  • This feature is useful if your computer doesn’t have enough RAM.  If you do have enough RAM, ReadyBoost won’t really help.
  • If your computer has a hard disk that uses solid-state drive (SSD) technology, you might not see an option to speed up your computer with ReadyBoost when you plug-in a USB flash drive or flash memory card. This is because some SSD drives are so fast they’re unlikely to benefit from ReadyBoost.
