I'd like to buy a motherboard which support 2 slots M2 NVME PCIE 4.0.

A lot of current motherboards support 2 NVME, but only one with PCIE 4.0.

I found that AMD offer the X570, but I can't find nothing for intel.

It seems that the Z690 support PCIE 5.0, so can it support 2 NVME PCIE 4.0?

From the link that you posted the Z690 support only one 4.0, check the section "High Speed M.2 Solution" on asus site.

Sorry for my dumb questions, but here is the specification page:
____
  • Slots
    • 3 x PCIe x16 Slots (PCIE2/PCIE3/PCIE5: single at Gen5x16 (PCIE2); dual at Gen5x16 (PCIE2) / Gen4x4 (PCIE3); triple at Gen5x16 (PCIE2) / Gen4x4 (PCIE3) / Gen3x4 (PCIE5))*
    • 2 x PCIe Gen3x1 Slots
    • Supports AMD CrossFire™
    • 1 x M.2 Socket (Key E), supports type 2230 WiFi/BT PCIe WiFi module and Intel® CNVi (Integrated WiFi/BT)
    *Supports NVMe SSD as boot disks
  • Storage
    • 8 x SATA3 6.0 Gb/s Connectors*
    • 1 x Hyper M.2 Socket (M2_1, Key M), supports type 2260/2280 PCIe Gen4x4 (64 Gb/s) mode**
    • 1 x Ultra M.2 Socket (M2_2, Key M), supports type 2260/2280 SATA3 6.0 Gb/s & PCIe Gen3x4 (32 Gb/s) modes**
    • 1 x Hyper M.2 Socket (M2_3, Key M), supports type 2260/2280/22110 PCIe Gen4x4 (64 Gb/s) mode**
    *If M2_2 is occupied by a SATA-type M.2 device, SATA3_7 will be disabled.

    **Supports Intel® Optane™ Technology
    Supports Intel® Volume Management Device (VMD)
    Supports NVMe SSD as boot disks
    Supports ASRock U.2 Kit

My goal is to have a RAID 0 with 2 NVME PCIE 4.0. Do I need to buy the asus hyper card or I have everything I want from the motherboard?

they just give them a "hyper" marketing name.
raid 0? why?
Why do you think is not a good idea?

I'm going to build BSC full node which require "1T GB of free disk space, solid-state drive(SSD), gp3, 3k IOPS, 125MB/S throughput, read latency <1ms. (if start with snap/fast sync, it will need NVMe SSD)". Also I read in a lot of discussion online the importance of ssd extreme performance and with RAID 0 I can achieve really good performance on both read/write.

What do you suggest?

Using the drives in RAID would mean lowering the speed to MSATA and getting much lower performance.

When connected via pice 4.0 your drive is already pushing data at nearly 5GB per second, which is already 40 times faster than the minimum required for a BSC node, and probably way more than it will ever need. In any case, RAID would reduce performance significantly.

the spec calls for 3k iops. Even the slowest pcie 4.0 nvme drive will run at 12k iops, easily 4 times what is required.

I did some research about it and I didn't know it. Thank you very much for your knowledge!
So now the last question is Intel or AMD? Z690 vs x570?

I know that maybe there is no real concerning difference, but from your experience would you prefer AMD based solution or Intel?
