I'm the author of the Apple SSD article that klanomath linked to in their comment and I wanted to clarify some things that seem to have been misinterpreted.įirst of all, the Mid 2013 release of the MacBook Air 11" absolutely can use the faster PCIe 3.0 x4 drives from the 2015-2017 MacBook Air 13", which I refer to in the article as the Gen. This implies that the drives from the 13" 2017 MBA will fit physically into the 2013 11" MBA, but because of the firmware, they won't work. 4A drive found in the other Apple computers of the era. In fact, if the 11″ MacBook Air wasĬonfigured with a 512GB SSD from the factory, it already included the It offers very fast read/write speeds of 950MB/s.

Also remember that you're comparing the 11" to the 13" model and those are different with respect to space.įrom, I was able to find an excellent image showing the difference with the interfaces. The 2015 through 2017 MacBook Air laptops use the exact same interface, so, those are compatible. The 13-inch Touch Bar-less MacBook Pro 2017 has a problem that requires the solid state drive and the. The 2015-2017 MacBook Air 13" uses a proprietary PCIe 2.0 x4 SSD. If the SDD in a 2017 MacBook Pro fails, the logic board needs to be replaced, and vice versa.The 2013-2015 MacBook Air 11" uses a proprietary PCIe 2.0 x2 SSD.
