Good morning!

I understand the laptop has 3 SSD slots, and the two M.2 2280's have different compatibilities. One is SATA/PCIe NVMe compatible, the other is just PCIe NVMe.

I ordered mine with just one SSD installed, no other hard drives. My question is... Was the pre-installed hard drive installed at the PCIe/SATA slot or the PCIe slot? Which slot is which? 

Thank you,

Andrew
