I had purchased a Vista Ready Upgrade 8GB Flash Drive. I am getting extremely slow speed on that. I am not able to get proper output here. It is extremely slow. I had tired to enabled ReadyBoost here but that is not working fine. I had gone through some registry hack here which does not looks to be working well. Is there is some problem with the usb. How can I improve the speed here. I am not able to find any solution on it.
