So I heard that if you copy your OS from a HDD to a SSD you can lose speed. Currently my Corsair GS 120gb is giving me problems like freezing my computer. I want to upgrade to a Kingston Hyperx 3k and use the upgrade kit to copy over my OS. My question is will I lose speed on the Kingston SSD if I copy my OS from my current Corsair SSD to it?

This guide by HTG does a real nice job of addressing problems that commonly occur when migrating an os to an ssd.
However if possible do a clean install because a clean install is always better.
