I'm customizing an HP Envy 15t for college. I will play games on this laptop, watch movies, and run various Mechanical Engineering programs such as CAD. I am stuck on which hard drive to choose though, I can choose between 1tb 5400ram Sata with 256 gb M.2 SSD or 512gb Pcle NVMe M.2 SSD for an extra $80 which one should I choose? To get the most out of my laptop.
