How to completely move my documents off of the C: drive

I've been curious about this before with vista. I remember theres a way
through group policy to move my documents to a network location but I was
wondering if there was a way to do it on the same computer? I have an SSD
that I want to put my Whole user folder onto for faster read times but I
don't know exactly how to do this through local policy. If there is a way can
someone help me out? Thank you.
