m2 SSD does NOT disable Sata 6 port like it says it will, issues?

[mxracer141]

I have a question for those whom might more about storage lanes than myself. Specs:

Motherboard: Z270 KRAIT GAMING (MS-7A59) (U3E1)
Storage: 1x Samsung Evo 960 Pro 512gb m2 SSD, 1x Samsung Evo 840 1TB SSD, 2x 2TB Seagate 7200RPM drives in Raid 1, 2x 512GB Seagate 500GB 7200 RPM drives in raid 0.

The motherboard manual warns you that:

The SATA1 / SATA5 port will be unavailable when an M.2 SATA SSD module has been
installed in the M2_1/ M2_2 slot

I have all of my drives plugged in, and oddly enough, I set it so only Sata3 port is emtpy. This means my Sata 1 and Sata 5 ports are filled.


Yes, this build works, amazingly. No issues whatsoever. But something doesn't match up, these ports are supposed to be disabled... Why is this working? Is it stealing bandwidth from the M2 SSD? Anyone know what the repercussions of this may be? Or WHY it is working so flawlessly?

Thanks ahead of time.

Because the 960 Pro is an NVMe drive, not a SATA drive.

m.2 is just the connection type.
They may be SATA or NVMe.
If yours was an m.2 SATA drive, it would indeed turn off those other SATA ports.

That completely makes sense and now I feel silly for asking. Bought NVMe because of the speed, completely forgot it interfaces directly with the PCIe lanes. Wouldn't have even questioned it, but I threw all of my parts into pcpartpicker, and it too flagged "don't buy this because you need more sata ports if you use this drive". Threw me for a loop.

Thank you for the insight and reminder

No reason to feel silly. Stuff like that catches all of us.
Especially with this current confusion over m.2 drives.
