NVMe is an amazing advance in storage protocols.  It upends many of the
assumptions that come with not seek time and having all your read-write
heads attached to one arm.

I apologize for misreading your original post.  I didn't see that your
motherboard had m.2 onboard.  I thought that you were talking about one of
the PCIe plug-in boards that provides multiple m.2 connectors to one PCIe
slot.

If you're using the onboard m.2 slot, and it has the proper keying for
NVMe, nearly any NVMe device should work.

Bifurcation is for splitting, for example, an 16-line PCIe slot into 4
4-line m.2 slots.
