The SSD Apple is using in this model is a custom M.2 PCIe unit which is only available from Apple currently.
OWC and others have shown there upgrade products but haven't started selling them. OWC is even planning on offering a larger size than what Apple offers! So hang tight as some options are coming soon.
If on the other hand you are planing on buy a system I would get the larger sized SSD model to start with.
