The last release of the 11″ MacBook Air in Early 2015 brought minor upgrades to a few components, but left the SSD tech virtually unchanged. The drives were the only of Apple’s product lines to keep the PCIe 2.0 x2 technology from the previous generation, but the drives were still modified with firmware changes that rendered them incompatible with earlier MacBook Air laptops. The new drives were also now branded “Apple” rather than with the third party manufacturer’s name, although the flash chips on the SSD make it clear that Toshiba and SanDisk were manufacturers.
