ASUS UX31LA SH51T Upgrade
I'm looking to upgrade my Asus Zenbook with a newer and bigger SSD. It now has a SanDisk drive, at 128GB. This is an m.2 slot, and I'm having a hard time finding the right fit and the right product. 256GB will suit me fine, but I was hoping to pass along the inquiry to the incomparably astute tech wizards gliding knowingly here. I also worry about ordering the wrong-sized SSD, an act that would reveal my tech illiteracy.
Let the SSD be the focus of your responses, if you would be so kind.
I appreciate it!
