Swift 3 SF314-42-R6T7 m.2 NVMe upgrade

Supposing I wanted to replace the included 512 GB m.2 NVMe storage to get more capacity, would it also be worthwhile to upgrade to PCIe 4.0 NVMe?

The included 512 GB m.2 drive is PCIe 3.0.  According to CPU-Z, the m.2 slot can support PCIe 4.0.  Is this correct?  Haven't been able to find anything official stating whether the m.2 slot is in fact PCIe 3.0 or 4.0.

    Thanks for your answer.  Related question: how do you know the motherboard supports PCIe 3.0 but not 4.0? 

    I could not find any documentation, official or otherwise, specifying which.  Machine's UEFI menu does not say.  Maybe someone has opened the case on the subject model to verify?  Might be printed on the motherboard itself.  If you have another source, please let us know.

    While a PCIe 4.0 NVMe drive would of course be backward-compatible, it wouldn't be worth paying a premium for a 4.0-capable drive if it's only going to run at 3.0 speeds.
    You are welcome, I have access to Service guide but you can find out the PCIe version by searching online for this model's specs, yes, there's no point in using a Gen 4 in a Gen 3 motherboard.

    Hi,
    Your motherboard supports Gen3 PCIe but Gen 4 M.2 SSDs are backward compatible with Gen3 motherboards, so you can install Gen4 M.2 NVMe SSD and it should work but I haven't seen anyone with Gen 4 M.2 SSDs in this model, so you have to try it at your own risk.
