Apple MacBook Air machines feature Intel processors and an exceedingly thin Aluminum body. None of the MacBook Airs have internal optical drives, Apple sells an external USB Superdrive (make sure to check compatibility with your MacBook Air when buying a USB drive, the latest USB optical drives from Apple are compatible only with the current version Airs). MacBook Airs came with either hard drives or SSDs, the current models are SSD only. Their HD/SSDs are not a standard 2.5″ format, and the interfaces have changed over time, so it is critical when upgrading to know the exact revision of the MacBook Air.
Following is a chart of all of the MacBook Air models, the types of RAM and hard drives that can be installed. Newest MacBook Air models are at the bottom.
