Hi well if you go for a Raptor drive you will see a difference. There is nothing faster than a SSD they blow away mechanical drives. I would unplug the old drive plug in the ssd boot and install windows on the ssd get the drivers and everything setup, then plug in the old drive boot and delete what you don’t want from it format the partition that had windows on it. You can’t copy a program as it would have installed files into windows folder that make it work your only choice is to reinstall your programs and to do that you would reinstall most of them to the old drive. So for example you go to install office first make 2 folder’s on the old drive called program files the other if you have 64 bit windows program files (x86) point your install to either one depending if it is a 64 bit or 32 bit program this leaves more room on the ssd as you don’t want it full. Your personal files will still be on the partition you did not format.
