#RAID0 #PCIeX16

Recommended Posts

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


Want to custom loop?  Ask me more if you are curious

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

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.

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) ?

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 ;).


80+ ratings certify electrical efficiency. Not quality.
