XPS-8930 M.2 PCIe NVMe SSD Question

Does anybody know what Make and Model of SSD is used in the XPS-8930 Tower Special Edition?

It is listed as a 2TB M.2 PCIe NVMe SSD (SKU 400-AXKN).

I saw in the XPS 8930 manual that it lists a maximum of 1TB for the M.2 slot as 1TB.  Is this a misprint or does it have to be partitioned into 2 drives in order to access all the space (2 TB).

I am upgrading from an XPS 8910, so using an SSD for a boot drive is new to me.  How does this work?

Thanks!
