I have an Asus Z170-A that's now a few years old. When I bought it I could only afford conventional 250GB SATA SSD and 1TB HDD combination. My Steam games are on the HDD.

With prices falling I would like to upgrade storage to move my games on to some combination of SSDs. I could easily add a single M.2 SSD, but I also started to look at the possibility of a RAID 0 configuration making use of the dedicated m2 and also a vacant PCIe slot.

I'm confused about PCIe lanes and if my board will support two new SSDs in this configuration? I have a GTX 1070 at 16x and from what I can see the Z170-A has 16+4 lanes. If I try to run an M.2 at 4x and another in a PCIe slot at 4x, will I be over what's possible?
