|It is not using the flash drive as RAM, it is making virtual memory using the USB memory. That why it doesn't show up in Task manager.|
For all the difference it makes you might just as well use you hard disk for virtual memory in fact you should be using your hard disk for virtual memory, it a lot faster than a flash drive.
The only time this might be advantageous is if your hard disk was so full there was no room for virtual memory. In that case you would have other problems that virtual memory wont solve.
In short, its a load of bollocks. Somebody that doesn't understand the difference between real memory and virtual memory.
