[SOLVED] Can I use a diferent second M.2 PCIe

Jan 7, 2022
Hi guys,

i have already buyed one 980 plus 1TB 7.000MB/s PCIe 4.0, should i use this SSD in the first slot and for the second slot the Western Digital Blue SN550 M.2 1TB 3.100MB/s PCIe 3.0.

Its that a problem the difference between speeds and PCIe?

I will use this PC for Gaming, this is my build Its that a good build?

Thank you guys!
