If you bring your favourite Apple device to any Apple store requesting internal storage capacity upgrade, unfortunately, Apple will decline to do so. In the eyes of Apple, what you buy is what you get.
Recently, I upgraded an internal 128GB Apple Flash Drive for the MacBook Pro late 2013 13 inch with Toshiba XG5 512GB PCIe SSD – NVMe (Non-Volatile Memory Express). Please refer to the product review.
Affordable small Mac devices usually come with only 128GB storage capacity which runs out in no time.
Compatible large-size storage SSD used to be very expensive. But you can now get it for under A$160 with an adopter. (512GB capacity)
Please refer to the following image for the adopter comes with the Toshiba XG5 512GB PCIe SSD – NVMe.
1. Before starting an upgrade, make sure your Mac device has at least macOS 10.13.5 (High Sierra – recommended to upgrade to macOS 10.13.6). (Compatibility list usually says macOS 10.13 (High Sierra minimum – but I believe 10.13.5 is minimum)
2. Make a bootable USB installation stick
Next, replace the internal Apple Flash SSD with a PCIe SSD for a faster and more efficient SSD.
3. Attach bootable USB and Timemachine backup external USB HDD to your Mac device
4. Switch on your Mac device while holding the Alt (Option) key
5. Choose bootable USB as your start disk
6. When bootable USB is fully loaded, choose Timemachine backup for the source and the newly installed balnk PCIe SSD as destination for installation.
7. During the upgrade, you are prompted to enter your password for your Apple ID. Please do so for smooth upgrade.
8. Your Mac device will restart after a while, then proceed with mail import and photo gallery restoration.
You are now set to go.
