They do disable SATA ports as they share the lanes. This is with all Intel boards.]]> Thu, 20 Dec 2018 08:41:01 +0000 https://forum.asrock.com/forum_posts.asp?TID=10454&PID=59034&title=m2-pcie-disables-sata-on-z390-taichi-ultimate#59034 https://forum.asrock.com/forum_posts.asp?TID=10454&PID=59027&title=m2-pcie-disables-sata-on-z390-taichi-ultimate#59027 Author: Zippies

On a new build using the Z390 Taichi Ultimate I installed 2 M.2 drives, one on M2_1 and one on M2_3 (the drives are Samsung 970 EVO M.2 2280 PCIe).

Now I have found that SATA 0,1,4,5 are all disabled. Samsung Magician lists both M.2 drives as PCIe Gen 3X4.

I was under the impression that M.2 drives using PCIe would not disable the SATA ports. Am I wrong or am I doing something wrong?

Thanks for any insight!]]> Thu, 20 Dec 2018 01:59:19 +0000 https://forum.asrock.com/forum_posts.asp?TID=10454&PID=59027&title=m2-pcie-disables-sata-on-z390-taichi-ultimate#59027
