I am thinking of buying the T460s with a base configuration and then upgrading the SSD myself.
If I choose to buy the 128GB SATA SSD, does this mean that the SSD slot can only have SATA M.2 SSD in it?
Similarly, If I choose the 256GB PCI-NVMe, then the SSD slot can hold only NVMe M.2 SSDs in it?
Is there even such a thing as a universal M.2 slot, that can take SATA OR NVMe SSD?
Thank you very much.
Solved! Go to Solution.

@helloguys - Thanks for the enouraging info
I also got the same feedback from the Lenovo sales rep via chat.
Is there a doc/publication where this is mentioned?
Just out of curiosity - what would the slot look like?
For a PCI-NVMe SSD to use 4 lanes(which the T460s is supposed), the SSD has to be M-keyed.
All the SATA SSDs that I 've seen so far are B keyed or B+M keyed. If the slot on the motherboard accepts SATA, then it has to be B+M keyed. In this case, the physical connections are missing, so the NVMe SSD would only be able to use 2-lanes.
Am I right or did I get all of this up-side down?

I don't have a T460s yet. Per https://en.wikipedia.org/wiki/M.2 M-key supports SATA as well. So I guess Lenovo got some SATA drives that work with M-key.
"For example, M.2 modules with two notches in B and M positions use up to two PCI Express lanes and provide broader compatibility at the same time, while the M.2 modules with only one notch in the M position use up to four PCI Express lanes; both examples also support SATA storage devices."
Also look at the last row (M-key) in the table. It says SATA is supported with M-key.
