What a pleasant surprise! Removing the blower fan housing reveals the teeny-tiny SSD.

We're happy to see a modular SSD, but not happy knowing it's bound to the T2 chip, meaning user-replacements are a no-go.

That said, there are plenty of other ways to add storage, so it's not a total loss!

This SSD looks very familiar—Apple seems to be re-using the same design we saw in the iMac Pro. That's probably a good thing, as parts availability tends to improve with more devices in circulation.
