It’s a great Myth that windows created such option like Ready Boost and people always try to enhance performance with their USB flash drive but its completely waste of time, see the truth behind
A formatted 4 GB USB can work as 1 GB RAM on Windows 7 PC. But the truth is far behind the way Windows shown to us.
Whenever we insert the USB, an auto play option is Pop up, you can find the several options depending upon the content of USB device. For the Blank Drive, you will get two option Open folder to view content and another is of readyBoost.
Believe me if you are doing this, stop pretending like fool!
Let me show you some of the stats that will explain all this.
I did this many time with my 2 GB RAM on Desktop, and tried to run some of the high performance eating application like VirtualBox and believe me after running a single OS with 800 MB RAM my PC start slowing down however I was not using any of the extra application. Here too ReadyBoost didn’t made any difference on my PC.
Currently I’m showing you result from my Laptop. Configuration of My Lenovo G580 is i5 second gen 2.4 GHz quad-core with 4 GB RAM, 5400 rpm HDD and onboard graphic memory.
I have Transcend 4GB device having 3.7 GB usable space.
Let me show you some of screen shot

Comparing PC with and without readyboost
What has changed in both condition, before and after readyboost, let me summarize
Total Memory in MB is same
Cache memory decreased by 5 MB
Available Memory decreased by 37 MB
Free Memory decreased by 17 MB
IN SYSTEM DEYAILS
Handlers increased by 122

Overall I have this chart prepared in Excel,
System memory usage is either increased by some points or not affected. So please don’t waste your time in such jokes.
The Bottom Line
The Main focused vision for readyboost is to enhance caching memory of the computer also called virtual memory. This can be useful when your system drive is running out of memory space and Windows is showing you message that Windows virtual memory is too low. You can try this Readyboost to see If this works or not. Well I’ll better suggest you to allocate 4 GB space from each of your drive for the paging memory. This will be most effective thing for caching you can do on your PC.
Do it as follow
Open System Properties > Advance system settings
In Advance Tab click on setting button in of Performance
In Advance tab of new window change Virtual memory option
On New pop up Uncheck automatically manage Virtual memory
Select each drive and provide recommended space in MB for virtual memory.
Save and restart your PC
After 3-4 Restart your Computer will start performing faster for all programs including explorer.
