NVMe Raid

[Veanie]

I want to build a system with 4 x NVMe drives in RIAD.

What PCIe sockets will I need on my system board to support the best data transfer speeds ?

Accepting that the GPU will be in a gen5 x16 socket, is it as simple as having 1 more x16 socket with a riser to hold all of the NVMe cards or would I need a system board with four x4 sockets ?

Can do it either way
Motherboard m2 slots or something like
Asus hyper m2 raid card

Raid card should be easiest
Just need 2 x 16 lane slots
Though its added cost

Motherboard m2 slots
You would need to know what Motherboard
And how the pcie lanes are allotted
On my x570 board I have 5 x m2 drives
Won't boot until I go in bios and change bifurcation settings
Which then gives 5 x m2 drives
But puts the gpu at x8 which is no big deal
Lose a couple of % fps

Whether there's actually any benefit with raid
Probably comes down to what form of raid you mean
Mirrored, striped,redundancy etc
And what your usage scenario is

That would not work on AM5 or 1700, because you wouldn't have enough PCIE lanes to support 4 drives.

This kind of usage is usually not appropriate on anything except HEDT.

Tetras may be right
Should say my motherboard was £900-1000 when new
So it definitely pushed the limits of x570
It's not your average board

I can still raid the drives
By having gpu at x8
And 5 x m2 at x4 pcie 4
And still have 4 x sata ssds too
This board has a dimm.2 slot which takes
2 x m2
Really don't remember if that has its own
Chipset with extra lanes
I don't raid mine anyway I use windows storage spaces instead

Still the question is
What do you want to achieve by
Doing it?

A workstation set up may be more appropriate
Though also more expensive
