Upgrading and Servicing Guide

you can try this site

Welcome to Crucial USA

or look at the model that is in place, and see if it is available in a larger capacity

[PCJimbo]

Thanks for all your help.  I found a 2T SSD card at Crucial which I will install in the 2nd M2 slot.

[Prométhée]

to make it clear
you have a slot occupied with the original m2 ssd
and a slot that must be occupied with wifi
you can only use the indicated m2 ssd slot!

[PCJimbo]

Oh! I didn't know that. Thanks for the heads-up.
