I used macrium reflect to clone a 40GB partition onto my new 120GB SSD. Just a couple of things first. You want to install and initialise the new drive and then use the clone option in macrium reflect to the new drive. You can then use disk management in windows to expand the partition to fill the remaining space. After this, unplug your old disk and reboot, making sure the correct disk is set to boot in the bios options.
