Different class 40 SSD drives

I am looking at purchasing an XPS 8920 from the Dell outlet. One of the computers has a:

256GB PCIe M.2 Class 40 Solid State Drive whereas the other one has a:

256GB PCIe M.2 NVMe Class 40 Solid State Drive.

From a practical point of view what is the difference between one drive being NVMe and one not?

Thanks!

I don't think Dell offers two different 256 GB PCle M.2 SSDs for the XPS 8920. I think they are the same drive, they just left off the NVMe part.

I was thinking that might be the case. However, they do have different part numbers.

I went the the Dell outlet site and all the XPS 8920s with the 256 GB SSD say NVMe now. I couldn't find any part numbers for the drive.

RE: Different class 40 SSD drives

Thanks for your help. I only found part numbers by adding the computer to my cart and in the checkout page clicking on detail view. I Googled the part number and found some hits, but nothing that described the drive.

I see two different part numbers and one of them explicitly states NVMe. My concern is whether the other part (that does not indicate NVMe) is actually running on the SATA bus and only providing HDD type speeds.

Can you post the part numbers?
