Product: HP ProBook 640 G4 Notebook PC
Operating System: Microsoft Windows 11

I recently bought a Leven nvme drive to put in my ProBook 640 G4.

 

LEVEN JP600 256GB 250GB Up to 2100 MB/s PCIe NVMe Internal SSD (Solid State Drive)- Gen3x4 M.2 2280 3D NAND (Packaging May Vary) https://a.co/d/1ehlWD7

 

I cloned the OS from the SSD to the m.2 and ran speed tests after, but am finding the speeds a bit slower than I anticipated they'd be from the Amazon reports.  I've never had an m.2 before and don't know if this is a processor limitation, but am seeing speeds around 1100/1100 whereas there are reports of well over 1600 and close to 3000.

The bandwith limitation is normally because of the processor/chipset.

 

I can't say that I have ever heard of the SSD brand you state that you used. 
The manufacturer's "Max read speed up to 2000MB/s" means that what you are seeing is within specifications.

Okay, so the thinking is that I'm getting expected speeds because of the i5 7th gen processor I have.  The higher 3000/3000 speeds are probably newer processors?

It is more of a combination of chipset and processors. 

Newer generation processors combined with their accompanying chipsets do provide higher bidirectional bandwidth.
