If im swapping my current ssd with my os to this, can I just do a backup and restore? Or do I have to reinstall everything?
Not sure why the other post told you that you couldn't do it and then proceeded to tell you how to do it. I've done this on 5 different machines. It's easy. Acronis has always worked well for me in cloning disks. Please note that if your old hard drive has 200GB worth of data, you won't magically get all of that on a 120GB drive. So you may need to separate data (e.g., music and movies) from the rest and then clone.
