Is there a way to calculate the speed of your PCIe NVMe interface by counting lanes it uses ?

I am looking at a laptop with Core m5-6Y57, GPU is integrated, 8GB of RAM....


on Wikipedia it says this:

Peripherals include 10 lanes of PCI Express 3.0, in x4, x2, and x1 configurations.


it has an M.2 slot that supports PCIe NVMe SSDs...I wanna know whether it is x2 or x4 ... can someone help me with this ?

That CPU has 10 PCIe lanes and no GPU other than integrated, so its safe to say the M.2 would support x4.

That said, x2 or x4 what does it matter, it has a 1.1 ghz cpu, you aren't setting any speed records with it thats for sure. And in practical real world use you would never know the difference in x2 vs x4 performance. Only in heavy file I/O which you wouldn't be doing on a portable such as that one.

Actually no older M.2 PCIe NVMe slots are x2 The standard has been around since 2013. It even runs on PCIe 2.0 on old slots.
