3 x SATA Express connectors
6 x SATA 6Gb/s connectors
If you, only found SATA express ports, I suggest reading the manual.
Refer to "1-10 Internal Connectors," for the installation notices for the PCIEX4, M.2, and SATA connectors.
There is no IDE mode with the Gigabyte Aorus z270x Gaming 7.
So the hard drive SATA goes into a non-express slot? From the manual it looks like the SATA express is the same slots as the regular ones. I've scoured the manual and it looks like I'm plugging it into SATA 0 but its still not saying anything in BIOS. Iv'e changed the wire but nothing seems to work
Also if there is no IED is it even compatible? Which mode should I have it on?
