I have ROG 501VW laptop and I would like to install a new ssd.
While looking for information about compatible parts, I found out that my slot is m.2 PCIe x4 2.0
I would like to get the Samsung 950 Pro for the maximum performance, but since Samsung 950 Pro is PCIe x4 3.0, I was wondering if it will have any issues in the PCIe 2.0 slot. Will it have compatibility issues or loss in performance?
