So I was thinking about installing a second ssd on my legion 5 15ahp10. And I was inclined to buy a samsung 990 pro 1tb, the issue is this SSD is 4x4 and my second slot is 4x2. Is there any problem, other than performance loss, of me using a 4x4 ssd in a 4x2 slot? Sorry if this is a stupid question, im kinda new to the upgrading scene.
