"mpg b550 gaming carbon wifi" storage question

[Bobthecat]

I want to install a new ekstra storage in my build, but i am a bit unsure if i can put another m.2 in, without loosing the speed of my 980 pro?

spec
mpg b550 gaming carbon wifi

Ryzen 9 5900x

Radeon rx 6800 PCIe 4

RAM 2x 16 gb 3600 

ssd 980 pro 1tb PCIe 4

and old storage that i want to replace.

Yeah, it will work just fine. The first one runs on PCIe 3.0/4.0 x4 connected to the CPU while the second slot runs PCIe 3.0 x4 through the chipset. Both will run simultaneously at full bandwidth.

so it just have to be PCIe 3.0 and then i'm all good?

The second slot will only run at 3.0 speeds, but any drive will work since 4.0 is backward compatible. You’d just be wasting money on the faster drive since you wouldn’t be able to take advantage of the faster speed. But it would work just fine.
