I connected my sata cables from my Mobo into my hard drive,ssd, and optical drive. Which data ports do i connect the other ends. My GIGABYTE GA-Z170X-UD3 motherboard has sata six 6gb ports, three sata express ports, and 2 m.2 socket three connectors. Which ports should I use? Also for the other cables that plugs into the drives, there are headers that lie up upon different locations on that cable. Do i plug one of them in only and then use a different cable with all those headers, or can i just use that cables headers for like two of my drives.
