What is the lane speed of PCIe v3.x x1?

250 MB/s
500 MB/s
985 MB/s
1024 MB/s

The correct answer is: 985 MB/s

PCIe v3.x x1 stands for PCI Express version 3.x with one lane. The speed of a PCIe lane is determined by its version, and the maximum speed of PCIe v3.x is 985 MB/s. This is why option C, 985 MB/s, is the correct answer. Option D, 1024 MB/s, is incorrect because it exceeds the maximum speed of PCIe v3.x. Options A and B, 250 MB/s and 500 MB/s respectively, are incorrect because they are the maximum speeds for PCIe v2.0 and v1.0, which are older versions of PCIe and have different speeds. Therefore, they do not accurately represent the lane speed of PCIe v3.x x1.
