So maybe you already know about this trick, or maybe you never heard about it… 

Windows ReadyBoost has been around since 2006 and still remains a viable way to boost random disk reads with performance that is typically 80-100 times faster than random reads from traditional hard drives. This applies to to all disk content, not just the page file or system DLLs (applicable on Windows Vista, Windows 7 and Windows 8).  It works by using flash memory, a USB flash drive, SD Card, CompactFlash or any kind of portable flash mass storage system as a cache for the Windows operating System.

Getting Started using ReadyBoost:

(1.)  Obtain a USB flash drive, SD Card or CompactFlash Drive (Minimum 256MB, Maximum 4GB).
I prefer to use a USB Flash Drive and place it on an empty USB port at the rear of my Tower.  That way, there is minimal risk of getting bumped or unplugged.
(2.)  Make sure your flash device contains no other files on it (for maximum performance).
(3.)  Plug your preferred flash device into an available port and you should see a Properties Dialog Box open up (such as illustrated above).
(4.)  Click the Tab on the Dialog Box that says “ReadyBoost”. Select the radio button that reads “Use this device”, then click on “OK”. Altenately, you may use the slider that reads “Space to reserve for system speed” and adjust accordingly.  By default, Windows will leave this at the maximum threshold.

To Quit using ReadyBoost:

(1.)  Open up “My Computer” and locate the flash device you are currently using for ReadyBoost.
(2.)  Right Click on the icon for that Drive and select “Properties”.
(3.)  Navigate to the ReadyBoost Tab and select the radio button that reads “Do not use this device”. Click “OK”.
