I am thinking of upgrading my mid 2013 MBA SSD from 256 to 1TB.. Can easily find those M2 PCIe adapter from Lazada but I am only worry about the replacement SSD size so not yet decided to know what brand of SSD to purchase.. Saw many China Macbook user successfully upgraded their SSD without much of issue but good to take a look on the link here before making your decision.. https://forums.macrumors.com/threads/upgrad...2-nvme.2034976/
