Could USB speed my computer up

I read some article like this, http://stechnotrick.blogspot.tw/2013/03/how-to-use-usb-pen-drive-as-ram-of.html

It is about setting virtual memory to speed computer up.

My computer have 4 GB ram and always ran 2 virtual machine that are winXP and Linux.

Sometime my computer's memory is not enough to use.

I had already setted 6GB virtual memory to my "disk D:".

Does computer set virtual memory of USB is better than disk's?

My computer only has "Sata 9500325 of disk" and "USB 2.0 "

I survey the information of hardware speed .

The max speed of Sata2 is 300 MB/s. The max speed of USB 2.0 is 60 MB/s.

So I don't need to try USB virtual memory, right?

Try it out and see if it speeds it up or not, you can never get enough ram.

Ha Ha !

I will try it later. But the first problem is I need to find a performance testing tools. XD

If you're looking to benchmark your computer you should read THIS when you get around to doing it…

As for the software itself, I've always sided with simplicity myself. Use CPU-Z. No bells and whistles but its powerfully simple.
