Samsung just launched the 980 pro. I already had a 970 pro and I thought about adding another 970 pro in raid 0. There’s been conflicting reports about if there’s even an improvement or not. One guy I saw had double the speed as what I would expect from raid 0. And then there’s other people who have negative results. Just curious if anyone here with x570 has tried this occupying the slots on the motherboard. Specifically crosshair from Asus. I think the other issue is it’s not bootable.
If you want to use PCIe 4.0 NVME drives like the 980, then it depends on the PCIe lanes available. I have the X570 Xtreme, which has 3 x M.2 slots. Slots 2 and 3 share their 4 lanes, which means that if both are populated, then you only get 2 lanes each, which would be equivalent to 4 lanes of PCIe 3.0. I have 2 NVME drives in slot 1 and 2, with the third vacant, which means that I get the full 4 lanes per drive. Some motherboards will also share the lanes one of the M.2 slots with one of the PCIe slots, so that’s also something to watch out for. However…
In your case it shouldn’t really matter either way, because the 970 is only PCIe 3.0, so it shouldn’t be affected by only having 2 lanes of PCIe 4.0. You should get full performance, but I wouldn’t count on double.
Thanks for the reply. I’ve been debating on how to install these two 970 pros. I would have to disassemble my water cooling SLI setup to install one in each slot. Or could I use a PCI adapter? If I understand correctly… both graphics cards are running x8 x8. So that would leave the last slot as X4. Would that be enough bandwidth for both and raid zero? Or is there anything to know about doing either way? I saw a video of Wendell did and he was successful doubling the speeds of 960s. He used the onboard m.2 slots though.
You’re gonna have a bad time and see no practical benefits.
Besides doubling my storage capacity? Actually Wendell was successful.
