is it better than nothing? I have 2gb ram.
*UPDATE* I out in the 1gb flash drive with nothing on it, setup readboost and it is good. Still says only 2gb ram in properties, is that right?
Yes. It only reads the System Memory. Of that you have 2GB. This is only a flash based RAM. It will be barely used with 2GB alredy on the system. If at all.
