I am building a NAS (truenas) and I want to have an ultrafast storage pool for working with video editing. I would like to use a total of 8 M.2 NVMEs in a raid setup w 2x parity.
The solution that seems like the best way would be to use 2x Asus Hyper m.2 gen5 Card (https://www.asus.com/motherboards-components/motherboards/accessories/hyper-m-2-x16-gen5-card/) with 4 drives on each.
However. For a Asus Hyper M.2 card to work you need a PCIe x16 slot that supports bifurcation (4x4x4x4). So to have 2x of these cards installed and working I would need two PCIe x16 slots with bifurcation and I can't find any information if this is possible? It seems that every mobo behaves differently when using the PCIe slots and some have a limit on the speed depending on what kind of cards you install...
I would like to install a 25G sfp+ card also, but other than that I don't need a beefy GPU - would prefer a CPU with built-in GPU.
ECC ram would be nice. Low power consumption also. The only computing power I need is to run the file transfer and software raid, etc. in Truenas
Does this motherboard exist?
