Compatible Mac models

This 256GB PCIe 3.0 x4 SSD uses a proprietary 12+16 pin connector and AHCI protocol. It fits MacBook Air Early 2015 through Mid 2017 and MacBook Pro Early 2015 to Mid 2015. The drive also upgrades Mid 2013 to Late 2014 MacBooks, iMacs and Mac Pros with nearly double the read and write speeds of the original storage.

Who this suits and who it does not

Owners of the listed Apple models needing a direct replacement or a speed upgrade for the original blade SSD will find this part matches the factory connector and form factor. Buyers with Macs newer than Mid 2017 or those requiring a different connector or protocol should look at other options.

Deciding specification

The proprietary 12+16 pin connector and AHCI protocol over PCIe 3.0 x4 are the single details that determine fit. Verify your Mac model identifier against the compatibility list A1466, A1502 and A1398 before purchase.
