Use readyboost when you have low physical memory (RAM).
If you have sufficient RAM (eg 4GB and above),then it is unnecessary to use Readyboost.
Buy an SSD instead.
what if you're doing a CAE calculation and it's filling up your ram even though you have 8GB? (I know 8GB isn't that much but IT won't let me have more)
