I just want to check that my understanding of Ready Boost is correct. From what I understand you plug in your flash drive and Ready Boost enables the storage capacity on the flash drive to be used as RAM, right? So I've done a bit of research this morning and found that it has a 1:1 ratio, which means what?? If my laptop only has 1GB ram, I can only plug in a 1GB flash drive for a total of what is essentially 2GB ram? So this means if I was to get a 2GB flash drive, it would be pretty much useless?
