Does this use PCI-e?

I have looked at the teardown, and I have a few complaints, but those are reserved for Meta when I do a deeper look at the teardown of the machine

It looks like this uses PCI-e instead of Apple proprietary SATA as the older models use from what I can tell, or is it still Apple proprietary SATA?

Is this true? If it is, the Air may finally be upgradeable with the storage, but not memory wise

Answered! View the answer I have this problem too

Is this a good question?

You are correct Apple has moved from the custom I/O's to the PCIe to gain I/O speed.

But, it appears Apples PCIe SSD board is not consistent with what others are making! Samsung just announced their SSD which they will be selling to other system makers and from the looks of it (very limited marketing pictures) it's different than what Apple is using. Yet, Samsung is the maker of the Apple unit (at least for now)! Go figure!

So here we have yet a different SSD sub assembly which is not interchangeable.

Looking at the bright side, each change has improved the performance! So it's clear SSD technology is still improving at a fast rate which is why each subsequent Mac Book Air model gets better.

And yes, RAM is still soldered to the logic board

I kinda figured there was something funky since the Mac Pro uses PCI-e, and it had the same look as the Apple proprietary SSD drives do at the same time.... time will tell I guess if they truly are proprietary, but it looks like it

The current Mac Pro systems use still a different physical I/O interface than what either Apple or Samsung are using on these SSD's (and form factor). The new Darth Vader Mac Pro (again from limited marketing pictures and what was stated at systems intro) is also using the same PCI I/O interface as the MacBook Air's for their SSD's.

So if the trashcan Mac Pro is proprietary, the Air pretty much is

At least they share the same part ;-}
