Some one may correct me if I wrong but I think this is how it works from Memory.
PCIE 3.0 Spees are PCIE 4.0 are Double 3.0
1 Lane 1,000 MBs PCIEx1 slot
2 Lane 2,000 MBs PCIEx2 Slot
4 lane 4,000 MBs PCIEx4 Slot The cards you have
8 Lane 8,000 MBs PCIEx8 Slot
16 Lane 16,000 MBs PVIEx16 Slot

So single lane should be happy with Sata SSD external running at 600 MBs
