Oh, go to system info, disk, components, storage and disk. Look for partition starting offset, divide that number by 4096. If it is even, then your ok, but if it is not a whole number, you alignment is off. That could be slowing you down. Also make sure your defrag is turned off, and disabled in services. When you did the fresh install, defrag was probably turned on by default. I have an ssd in my other Asus, and although windows should align it correctly on a fresh, on miy first fresh install, it didn't.
