[SOLVED] Additional m.2 slot on MSI Z390-A PRO

Hello to all,

I am interested to know whether I can have another m.2 slot on my motherboard. The case is, I already have 500GB drive on my existing m.2 slot and I bought another 1TB. It would be great if I could combine them, if not i guess I will sell my 500GB and keep 1TB.

Here is a link to specification of the motherboard, I am just too dumb to read it. //www.msi.com/Motherboard/Z390-A-PRO/Specification

Thanks in advance for help!

Looks like your board doesn't have another compatible M.2 slot. You can get a PCI-E adapter, if you want to keep both drives.

Yes, I've read that from the specification. Do you maybe know how can I "install" another m.2 slot in my motherboard? Will the adapter have any kind of impact on the R/W speed of the drive?
