I just received my SSD and I want to use it for storing my OS and games but I'm not sure what the correct procedure is for doing this properly. I keep reading that the data migration software really isn't safe and will ruin the performance of the SSD. Do I need to completely uninstall everything from my HDD before removing it from my pc? Also will I need to call microsoft for another Win7 key in order to install my OS on the SS?
