M2 NVME SSD only uses 2 Lanes instead of 4 Lanes

m 2 slot with pcie x4 lanes   Dan m2 vs nvme slot

Manufacturers can use the PCIe lanes to implement other fast components on their motherboards, like Ethernet, Wi-Fi, or additional NVMe

Transcend's PCIe SSD 220S follows NVMe and utilizes the PCIe™ Gen3 x4 interface, meaning four lanes are used for transmitting and receiving data A Samsung SSD that can use up to four PCIe lanes The numerical naming convention is used to define the size and functionality of the card, here is how:

arrr! 10k ways slot A 4 lane NVMe SSD will have twice the bandwidth than a 2 lane NVMe SSD Most 4 lane NVMe SSDs have one key, unlike the SATA SSDs which It will not affect the videocard And as been said, the NVME slot will go to PCIe instead #2
