15-cs0073cl - does it have 4 PCIe lanes

[rcohen]

MODEL 15-cs0073cl  HP Pavilion 15.6" Touchscreen Laptop

Does it have 4 PCIe lanes as I want to replace the 1TB 5400RPM SATA Hard Drive with the samsung 970 PRO 1tb pcle nvme ssd. My understanding is that unless 4 lanes are present, the ssd does not work at full capacity and the extra cost for the 970 pro is not worth it. I cannot figure out how to check if there are 4 PCIe lanes.

Thank you in advance for your help!

SSD i want to add: Samsung 970 PRO Series - 1TB PCIe NVMe - M.2 Internal SSD Black/Red (MZ-V7P1T0BW)

 M.2 modules with two notches in B and M positions use up to two PCI Express lanes and provide broader compatibility at the same time,

While the M.2 modules with only one notch in the M position use up to four PCI Express lanes.

Are you saying that 970 pro would work efficiently on my 15-cs0073cl

Yes it would utilize all four PCI Express lanes.

thank you! i understand that there are 12 express lanes total with the processor for the laptio

do you by any chance know how many express lanes are used by other things in the laptop? for example, if 4 express lanes will be used for the samsung 970 pro ssd, how would the remaining 8 express lane be distributed/used for? 

i apologize if the question sounds primitive but i am trying to understand how all this works.

thank you in advance for your patience and for getting back with me!
