PCIE M.2 adapter cards (self.buildapc)

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?

Performance would also depend on if your x16 slots are PCIe gen 3 or gen 4. Gen 4 is backwards compatible, but don't overspend on gen 4 SSDs if your mobo is only gen 3.
