3 Storage
When it comes to storage, the 12″ MacBook has an edge over the Air. It provides enough room to upgrade up to 512GB of SSD storage. The new Air can only go up to 256GB of SSD storage. Obviously there’s a lot of factors at play here, including whether or not you have an external hard drive and how much you rely on cloud computing, but for sheer internal storage, the 12″ MacBook easily comes out on top.
