Hello, So I am looking to expand my laptop's storage but the marketing material is making me a little confused, was wondering if someone could help clear it up for me. It says *1 port SATA only, One line in the manual says it has a slot that supports SATA and PCIe, another that says it supports PCIe, and yet another that says supports SATA. So do all 3 slots support PCIe or don't they? Feel kinda dumb trying to figure this out. Drive Model: SAMSUNG MZVLB1T0HALR-00000 (this is what is currently installed says NVMe when I looked it up) Link to the marketing image and screen grabs from the user manual: https://imgur.com/zmkUpvS
