Z390: M.2 SSDs and disabed SATA ports

rknox wrote: Okay, this M.2 topic is confusing. My question is for the Z390M-ITX/AC. The specs state: If M2_1 is occupied by a SATA-type M.2 device, SATA3_1 will be disabled. I too want to maximize the SATA ports available. If I use a NVME M.2 device instead of a SATA-type M.2 device, then I should be able to use all 6 SATA ports, including SATA3_1? Is that correct? Thanks,

I went ahead with the Z390M-ITX/AC build, and answered my own question. Great news: the ASRock stated restriction applies as suggested, to a SATA M.2 device only. I have the Samsung M.2 NVMe 970 Evo Plus installed as boot drive and additionally successfully attached a hdd drives to SATA3_1 (pic attached). This gives me a potential configuration of 6 hdd drives plus NVMe boot.

Dear AntoMac93,

For your reference, kindly refer to the following information.
M2_1, SATA3_0, and SATA3_1 share lanes.
M2_2, SATA3_4, and SATA3_5 share lanes.

If either one of them is in use, the others will be disabled.

With thanks,

"Regarding your question, only
the SATA type M.2 connects to M2_1 will disable the SATA3_1 port.


If you are using the PCIe NVMe type M.2 at M2_1, all 4 SATA ports can be used.

Hi, I have a Z390 Extreme 4
I tried to install a 970 EVI NVMe M.2 at M 2_1 and M 2_2

Both times other Sata   drives were disabled.

I thought if it was an NVMe it would not disable.

Any thoughts, any way to get all the drives to work?
Thanks

Dear Amdir,

The [M2_3], [SATA3_4 and SATA3_5] share lanes. If either one of them is in use, the others will be disabled.

Thank you!

Dear Amdir,

Z390 Taichi [M2_1], [SATA3_0 and SATA3_1] share lanes. If either one of them is in use, the others will be disabled.
Please connect the NVMe SSD to M2_2 then all SATA ports can be used.
(Please check the specification of Storage)
