Hiya new builder here on my 1st build.
Got this lovely motherboard and nearly ready to start, but I have a question about storage.

I originally bought a 1tb WD blue sn550 nvme drive for use as Os and storage drive, but quickly realised I needed a pcie 4.0 to get the best out of it so I've got a 500gb sabrent rocket on the way to use in that primary m. 2 slot.

The question I have then is do I keep the WD drive and put it in the 2nd slot, or would I be better off retuning it and swapping it for a regular ssd for mass storage? Would having both slow them down/cause excessive heat etc?

Hope that makes sense pls forgive me if not I only barely know what I'm doing :)

Thanks in advance
 
I thought I read somewhere that on this mb there can be an issue with using both and reducing bandwidth, but clearly I have no idea what I'm talking about, so all good! Thanks for the response

The top M.2 slot runs at up to PCIe Gen 4 x4 bandwidth direct from the AMD CPU. The bottom slot runs at up to PCIe Gen 3 x4 bandwidth using lanes from the B550 chipset

Yeah, just put the rocket in the top slot and the WD in the lower slot, job done.

You probably won't even notice the difference when all said and done.
