Raid 1 in asus prime z390-A

Hi
I have an Asus Prime Z390-A motherboard with 32GB of RAM and an i5-8500 processor. I wanted to set up a RAID1 array with two Samsung 990 Pro 1TB drives, but I noticed I can’t fit a single M.2 NVMe drive in the M.2 slot. My question is: if I buy an ASUS HYPER M.2 X16 CARD V2 adapter, will it work if I connect it to the slot where the graphics card is?

I believe this page lists the compatibility for that add on card

I don’t see the z390a listed but maybe it’s there somewhere?

I think you need to ensure that the motherboard supports the bifurcation.

I don’t know if yours does or not.

But keep in mind this only matters if you’re using bifurcation e.g. multiple m.2 drives in a single PCIe slot.

If you only need a single m.2 drive in the slot you can use simple adapters like these

Pcie to M.2 adapter

If you do need multiple m.2 and you don’t mind possibly less performance you can also use a PCIe HBA adapter that does the PCIe lane multiplexing on board and does not require CPU bifurcation, I’m using this one

High Point Rocket 1204 PCIe 3.0 x8 4-Port M.2 NVMe Switch AIC

:backhand_index_pointing_up: This type of card can go in any of your PCIe slots because it does not require the CPU to split between multiple PCIe devices, it includes the PEX 8747 chip onboard to do it instead

The choice depends on how many drives you want in how many slots and what kind of performance you need between them. If you’re ok with losing your top PCIe slot and you need the performance then the Asus card you listed sounds the best. But if you only need to solve the problem of “not enough m.2 slots” these latter solutions might be easier and won’t occupy your boards best PCIe slot
