I'm facing trouble setting up two NVMe M.2 SSDs on my Gen 1 T14. After some research, it seems the Intel T14 Gen 1 doesn't support NVMe in the WWAN port because of Thunderbolt usage. The PCIe interface isn't available there. When I try to install an NVMe drive in the WWAN slot, I see both nvme0 and nvme1 listed in BIOS but only the main slot shows the actual SSD. It's unclear if the WWAN card works independently or needs a different configuration. I'm considering switching Thunderbolt mode to free up lanes for the WWAN slot. Additional details: Windows 11 64-bit, Linux environment, ThinkPad T14 Gen 1, Intel i5, SODIMM and SSD storage, BIOS version 1.26 from August 2022. Useful links are available if needed.

The design suggests it's intended for Wi-Fi cards, pointing to an NVMe E key. I question if an M key NVMe would even fit there.

Thanks for your message. The WWAN is designed for cellular 4G LTE cards, and the WiFi is built into the laptop's motherboard. It seems the keying matches because you've recently added a secondary SSD.

It seems quite unusual. LTE cards are quite complex! It could definitely be a Lenovo innovation. It’s possible the only compatible model is a specific card they produce. The pin configuration is unclear, and details like the aerial in e-key might point to something very particular. You might need to talk to a Lenovo specialist—most answers would likely say no. But it’s also conceivable there’s a workaround that isn’t obvious.

It's interesting you're exploring this further. I checked the keying details and noticed it matches several formats, including PCIe ×2 SATA USB audio interfaces. Based on what you described, it seems more likely to be a USB-based solution rather than a direct PCIe card. Regarding USB 3.0 B Key SSDs, they do exist, though they're less common now. Your consideration of upgrading to an AMD motherboard is worth weighing as options become clearer.

PCIe refers to the slots on a motherboard, while NVMe uses PCIe lanes connecting to the CPU or chipset. The B key corresponds to SATA3, which makes sense. SATA3 has limited bandwidth compared to M key, similar to a desktop SATA port. If it supports SATA, it’s faster than USB 3.0.
