Apple 1tb PCIe for MacBook Air

Should work as long as there isn't an attached heat sink or something that might require different internal clearance. Apple used the same proprietary SSD drives / form factor in all Macs of that generation. The only difference with the OEM drives was the speed switch from 2x to 4x in 2015.

High Sierra (or newer) is required to use an NVMe drive instead of an AHCI as originally shipped. OWC actually sells drives up to 2TB, but if you have a reason to still run 10.12 Sierra then staying with SSUAX/SSUBX makes sense.

Excellent catch on width!

The MacBook Air is takes SSDs that are 22mm wide, 80mm long. An SSD that is noticeable wider than the connector won't fit.

Transcend made aftermarket AHCI drives such as the JetDrive 820/825, but I suspect production was discontinued years ago because remaining stock is unreasonably expensive.

I tried using SDXC storage idea myself back 2016-2020. Would not recommend. I vaguely remember it working OK on Sierra, but had nothing but regrets on High Sierra and behind. With High Sierra+ having an SDXC card inserted blocked deep-sleep/hibernation which caused the battery to drain at about 2%/hour even while sleeping. If I left it on the shelf over the weekend it would be dead by Monday. Also with High Sierra Apple's additional "security" prevented apps from running off of the external SSD unless they had first run from the home directory.

AFAIK Apple made these

Apple 1TB SSD SSUAX MZ-KPU1T0T/0A1 2x

Apple 1TB SSD SSUBX MZ-KPV1T00/0A4 4x

They do not seem to be advertised as fitting MBA 13-17

Has anyone tried/tested? Perhaps there is a space/size issue?

I responded to one of your other posts here:

PCIe drive speeds for MacBook Air - Apple Community

about this issue....here is that reply:

FYI, Apple's OEM SSDs are not always interchangeable between different models of Macs....at least when running macOS. I've had macOS refuse to boot at all when a different Apple OEM SSD is installed internally, but that same SSD works just fine when booted with Linux. For some reason macOS sees some sort of difference in the SSD and may refuse to work at all, so don't assume you can just swap Apple OEM PCIe SSDs between different models. Many may work, but there will be some that will not.

Internal? I’d look at what OWC offers, as their doc, and their support, has been good.

All MBAs from 2013-2017 have SDXC slots. Seems like it would be more cost effective to add storage that way rather than trying to replace the internal SSDs.

I believe the OWC drives require you to update to High Sierra because that is needed to update the Mac’s firmware to work with third-party drives. If you even can find compatible third-party drives from anyone else, they are likely to have the same requirement.

These drives appear to be very old (>10 years).

This is currently available in the (U.S.) Apple Store.

LaCie Rugged Mini SSD 1TB

Just curious, why would you put any money into replacing the storage in an obsolete machine that can’t run a supported OS any more?
