I originally bought the NVME and a PCIe card for a desktop but the motherboard could not boot to it. Experience is a good teacher. A little research would have served me well.
I inserted the NVME into the original slot and the Liteon in the stacked slot above the NVME. It booted to the original Liteon without BIOS change and I cloned to the NVME. I selected the NVME in BIOS and booted to it. So far so good. But Windows assigned C: to the Liteon and H:(for some reason) to the NVME.
Stacking the drives made the ADATA run hot and throttle (I assume)
I pulled the liteon and Windows assigned C: to the ADATA. The drive ran much cooler and speed improved.
This was an improvement over the original Liteon. I would be interested to see what a Samsung would do.
Was it worth the trouble? It feels a little snappier. I suppose some function would benefit but I have not done much yet. I don't have the outrageous speeds of some NVME drives. It satisfied my curiosity of installing it, so that is something.
