How to Increase RAM on your PC Using USB | CONVERT A FLASH DRIVE TO RAM | READYBOOST GUIDE
With the introduction of Windows 7 came a cool sounding new feature called ReadyBoost. There was some talk for a while about how you could instantly speed up your computer by simply plugging in a USB drive and BAM, you have extra RAM to work with! This feature is also available in Windows 8 and Windows 10.
Not quite. First of all, ReadyBoost is not a substitute for actually adding extra physical RAM to your computer. That’s a fact. Will it help your machine’s performance? Yes, but it depends.
Overall, I haven't seen a huge difference in my usage when using ReadyBoost while working in Windows. For example, when opening programs like Office, Adobe, etc. Those have remained pretty much the same with or without ReadyBoost.
