Lutfij :
^ That depends on the board you're using and how the manufacturer has wired the lanes on the board to react when a particular device is plugged into it. Might I ask what your full system's specs are looking like at this point? Include the M.2 drive and we'll be able to deduce if the lanes will end up being shared.
* M.2 operates by taking 2 SATA ports thus their lanes are assigned to the M.2 slot. It's either an M.2 drive or two SATA ports if they are wired to each other. Same goes for the PCI-E slots.
