15-Inch MacBook Pro with Touch Bar Has Non-Removable SSD (macrumors.com)

At least it is fast. [1]

1345MB/s sequential write

2000MB/s sequential read

And 13 inch model's SSD is replaceable [2]

That's unfortunate.

>90% of Apple customers wouldn't replace their SSD anyways and why should they? In a cloud connected world local storage doesn't matter like it used to.

If you don't like it, don't buy it.
