Hi. You're questioning whether a specific M.2 A+E module fits into an M.2 M key slot. The info suggests A+E corresponds to PCIe 2, while M keys are PCIe 4, so technically it might be possible. However, practical compatibility depends on the exact model and manufacturer specs. Many systems use different key types (A, B, E, M) and combinations, which can cause confusion. Why do people seem inconsistent? It often comes down to differing standards and design choices.

The keys are irrelevant to its purpose. They combine and swap keys. It functions properly in a standard M.2 PCIe port.
