MacBook Pro – Does the 2018 MacBook Air Come with an NVMe SSD

Your MacBook Air (13" I presume) does not use a standard SSD drive in the 2.5" form factor that many others do. Instead it uses an SSD with a bare SATA connector on the end. It looks a bit like a standard memory DIMM.

I generally buy upgrade parts for my Macs via Other World Computing. there are others that are just as good, if you prefer, but this SSD upgrade would work for your system.

I would review the installation instructions to make sure it is something you feel comfortable doing.

It will be as if you swopped Macbooks. It will work perfectly as it was in first Macbook.

Side note:

You can restore your internal "Macintosh HD" hard drive to an external hard drive using Disk Utility in Recovery Mode, then boot from your external drive on ANY Mac. This is ideal if you want to switch between your home Mac and work Mac with only carrying 1 external hard drive which you can even encrypt before it gets lost or stolen. (Enable FileVault in System Preferences before restoring/cloning)
