iFixit on Fridaypublishedits teardown analysis of the 15-inch MacBook Pro with Touch Bar (model number A1707), just two days aftertaking a peekunder the hood of the 13-inch MacBook Pro with Touch Bar. Comparing the two Touch Bar-equipped notebooks to the 13-inch MacBook Pro without Touch Bar, whichiFixit also disassembled, the repair site has confirmed that only the baseline 13-incher with a standard row of function keys has a removable SSD.
Like on the 13-incher, this machine’s processor, RAM and flash memory are soldered to the logic board, meaning that the SSD is impossible to remove or upgrade.

Curiously enough, iFixit has discovered a hidden connector inside the machine that leads “nowhere,” speculating it could be for SSD data rescue in case of hardware failure.
“Based on our previous teardown, we’re speculating Apple included an access port for the integrated SSD,” explains iFixit. “Not a bad idea when it’s impossible to physically salvage your data out of a damaged machine.”

We’d still rather see a removable/upgradeable SSD, particularly in a machine targeted at pros—but this way if your logic board bites the dust, there might at least be a chance of recovering your data with Apple’s help. Keep making those backups though.
The same connector was found in the 13-inch MacBook Pro with Touch Bar.

Other notable findings from the teardown analysis:
Here’s the notebook’s trackpad compared to the iPad mini.
And here’s a closeup of the Apple-designed T1 chip that handles Touch ID/Apple Pay/webcam security an drives the Touch Bar, as seen on the notebook’s mustache-shaped logic board overlaid on top of Apple’s promotional graphics.
It’s basically the same spot that Apple’s marketing materials claim the T1 chip is. To iFixit, that came as something of a surprise considering there’s three similar chips peppered over the rest of the logic board.

In addition to both the 13 and 15-inch Touch Bar-outfitted machines not having a removable SSD, they also have non-upgradeable RAM and have their battery “solidly glued down”, which greatly inhibits repairs and recycling.
iFixit gave both the 13 and 15-inch MacBook Pro a 1/10 on its repairability scale.
