The T470p has a PCIe 4x interface limited to only two lanes. As such the maximum speed you can see is 1800MB/s. 

As such don't go buying the most expensive PCIe SSD. I have the 960 Evo 500GB which is rated at 3200MB/s read and 1800MB/s write I get around 1800MB/s for both.

 

Actually, in real life I have not felt any difference between it and the Samsung 851 SATA SSD I had installed before. As such I would advise against spending so much money towards a PCIe SSD + the caddy (only $30) and get a larger SATA SSD.

As far as I know, both T470 and T470p have the same limitation (i.e. 2 pcie lanes). I cannot talk for the t470s or X and Carbon models, and I would think the new T?80 series laptops have the full 4x pci lanes.

Again, I do not think that in real life you can tell the difference between a SATA SSD and a 2x or 4x NVMe drive.

I certainly haven't been able to feel a difference going from a SATA drive (550/550) to an NVMe (1800/1500). But your experience might be different. That's why I cannot recommend the cost of NVMe, given that it is close to 2x per GB.

In any event, the part you are after is FRU 01HY319. It is about $30 or less from Lenovo. The T470p does not require a wire, the caddy is all you need. Be careful, the T470 (non P) has a different caddy, different FRU code and requires a wire as well.

So long as you look for FRU 01HY319 you'll be fine.

Enjoy your laptop.
