So I have an MSI X670E Carbon WiFi and I've just bought a spare 4TB drive, my question is I currently have my Samsung 980 pro 1TB as my C drive in SSD-1 which is connected via CPU, the next slot down SSD-2 and real easy for me to get to is also connected to CPU, if I am gaming from the second slot as I want to install my games on the bigger drive, will I see performance degridation as they're both using CPU bandwith?
Or should I pull my GPU out and use one of the SSD slots which connect via the chipset pcie4 as both drives are pcie4?

Also 1 & 2 are pcie5

You won't see any performance difference if using the 2nd slot. It's rated for whatever speed it is. Using any device that runs that speed is what was intended.

Now if you're actively using both drives in some serious heavy small file changes then sure the CPU might show some slowdown feeding both but the likelihood of that scenario occuring isn't often and you probably aren't gaming while that's going anyway.


The only way speeds might be effected is if the 2nd slot shares lanes with the GPU. In which case the SSD might drop down in usable lanes(depends on board).


With that being said I don't even think the 5090 saturates PCIe 3.0x16 so in theory you shouldn't see any difference in gpu performance. I could be wrong but I remember reading something about how it still hasn't reached that bandwidth level yet.

Awesome Thanks Buddy!

Well, that was heart attack time for awhile, I put the new drive in SSD-2 and booted into windows, no drive, went into bios no drive, it hated that slot, so I moved it to SSD-3 and thankfully it showed up in the bios and windows just fine, but dayum I hate it when that happens!

That sounds very frustraiting. I wonder why that slot didn't work...

I've got no idea mate, PC's...
