          | " rel="nofollow - I am considering buying 2 ASROCK Z390 Phantom Gaming ITX/ac motherboards, but I have a question before buying. 
 This motherboard has 4 SATA3 slots (SATA3_0, SATA3_1, SATA3_2, and SATA3_3) and 2 M.2 slots (M2_1 and M2_2). The motherboard manual says "if M2_1 is occupied by a SATA-type M.2 device, SATA3_1 will be disabled". My question is: does this disabling apply only to "SATA-type" M.2 devices or also to NVME-type devices? That is, if I connect an NVME device like the Samsung 970 EVO to M2_1, will it still disable SATA3_1? 
 I want to simultaneously connect 6 storage drives to the motherboard as follows: 
 M2_1: Samsung 970 EVO (NVME device) M2_2: Samsung 970 EVO (NVME device) SATA3_0: 2.5" hard drive SATA3_1: 2.5" hard drive SATA3_2: 3.5" hard drive SATA3_3: 3.5" hard drive 
 Is this possible or is it not possible because SATA3_1 will be disabled in this configuration? 
 Thanks for taking the time to answer my questions!

          | " rel="nofollow - Dear Aadithya,   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.   Thank you! Yours truly, ASRock TSD |

          | My NVME drive in M_1 disabled Sata in slot 0 and 1. Is there anything in BIOS to fix this? It's a Samsung EVO 970 NVME drive. |

          | Dear Amdir, 
 Thank you for choosing ASRock.
 
 Regarding your case, which motherboard are you using?
 Also, please clear CMOS firstly and update BIOS to the latest version to check.
 
 Thank you!

          | Sorry about that. It's a Z390 Taichi. Cmos is clear and BIOS is the latest version. |

          | 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)

 Thank you!

 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

          | I always have the same question for Z390 Extreme4 ... I am using it for home nas type storage, it is not the best choice, but I wanted to know if I can connect an NVMe M.2 ssd without disabling any sata port on board. 
 The manual is unclear, it is not clear if the disabling is valid only using Mata Sata units or also with NVMe M.2
 
 I have submitted a support ticket for this question, as I have yet to purchase an NVMe M.2 unit

          | 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,
 ASRock TSD

          | 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.
