On Z-170A board: either M.2 SATA or two SATA devices -- but not both!?

[c627627]

Could someone clarify what Asus means when they are talking about connecting an M.2 drive to a Z-170A board.
They say that M.2 socket shares SATA ports with SATA express.
So do you completely lose access to two SATA connectors if you use an M.2. drive because they share ports?

So with an M.2 drive in, you can then only connect four SATA devices and you have to leave the remaining two SATA Express devices empty, you can't even connect DVD drives to them?

Not sure about your board but I only loose access to SATA1. All the rest are fine.
