Sintech M.2 (NGFF) NVME SSD to M2 A/E Key WiFi Port with 20cm Cable(M.2 Only Provide PCIe 1X Lane)

Is there a max speed & capacity? 256gb, 2200mb/s works but not 1tb, 3500mb/s nvme.

Is this compatible with a gen 4 ssd?

I understand this is x1 pci-e, but what version of pci-e? 1.0, 2.0 ...

Will this works for dell wyze 5070 ext thin client? Have to install nvme 1tb ssd.I'd appreciate if somebody out there already tried it and let me know
