Hi, I have purchased 4 XPS 15 9560 (big battery, max spec). EXCELLENT MACHINES! Though wish the camera was in a better position. The SSD is a 1 TB PCIe. I would like to upgrade the SSDs from 1 to 2 TB SSD PCIe. Does anyone know if this would work for certain? I am thinking of the 2 TB PCIe Samsung PRO device. Possible problems: Motherboard, BIOS, etc..
