PCIE M.2 adapter cards (lemmy.world)

I'm considering adding more storage to my PC, and came across PCIe to M.2 adapter cards. I was wondering if performance would suffer on the adaptor card vs directly on the mobo? The M.2 slot is pretty much a PCIe x4 slot, so a a PCIe x16 should be able to drive 4 M.2 SSDs without issue right?

Thanks for this, I didn't know about the bifurcation or total PCIe lanes at all. It looks like my mobo supports 8x/8x on the 2nd 16x slot which makes it a little less attractive than the potential of eventually jamming an additional 4 M.2 drives.

I gotta look a bit more into the PCIe lanes though, I don't feel like I really understand what I actually have available with my hardware.

Edit: spelling

You're welcome. It's a big gotcha that people aren't aware of until they get into homelabbing.
