Solved!
Go to SolutionLatitude E7270 with NVMe SSD running at 2x.
Hello All,
I have a Dell Latitude E7270 and have upgraded the SSD in it to a Samsung 950 Pro NVMe drive. I have installed Windows 10 on it and the performance is good, but I noticed something odd about it. When I run the Samsung Magician software, it is detectign the PCIE port as running at PCIe 3.0, but at 2x lanes, which is cutting my read speed in half.
Can anyone confirm that the E7270 only has a 2x pcie lane for the NVMe ssd's? I could have sworn I read online that it can support 4 lanes for an ssd.
Thank you all for your time!

Thank you for the reply. I am a little disappointed to read but I can see your point of it only being available in the higher end laptops. Sad to see that other vendors are including 4x pcie nvme in their business class laptops but not Dell.
Thanks again for the answer and support!

Can you tell me the benchmark with using the nvme ssd? I was thinking of upgrading to nvme but if the performance is cut significantly, I might just stick to regular ssd.
Thank you

Sure. Here is the specs of the laptop:
(Yes, this laptop supports 32GB of RAM)
Laptop is a 7270
You can see its PCIe 3 but only wired 2x.
The 1600 MB/s is about the max your going to get out of a 2x PCIe read or write. The 900 Write is due to the 256GB Samsung being speed capped at that rate. When I had a 512 Samsung NVME, I got around 1500 write (I put the 512 in my desktop in case you question why i went down to 256 in my laptop.)
Feel free to ask any other questions and I will be happy to answer what I can.

I think you'll find the only Dells that support 4 lane PCIe NVMe are the high-end Precision, Alienware and the very newest XPS models - none of the Latitude models do.
