#RAID0 #PCIeX16

Will an m.2 expansion card in RAID0 config run faster in PCI/eX16 (where I'd normally put graphics card) than in PCIeX16(running at PCIeX8) ?

How many m.2 drives are you planning to install?

I don't think they will be able to saturate a PCIeX8 link, so no it probably will not run faster.

Maybe, but the only nvme RAID capable cpus are x299and x399, both of which should have several x16 slots

I got a bootable RAID0 on my Z370 (2xm.2 nvme) which has much less PCIe lanes ^^

I'd read everything linked here

These drives likely run through the Z370 chipset rather than using the cpu PCIe lanes. The bandwidth between the cpu and chipset is roughly equivalent to 4 PCIe 3.0 lanes. So there is a potential bottleneck if the two drives are saturating their NVMe connections.

I would think this depends on the expansion card. If the card can fit in a 4x slot, no. If the card can fit in an 8x slot, no. If the card only fits a 16x slot, I don't know, but likely no .
