When is 8 better than 256?
Q Which is better to have in a MacBook Air – 128GB storage and 8GB RAM, or 256GB and the standard 4GB RAM? Andrew Todd
A Regardless of whether you are buying the 11-inch or 13-inch model, if you can only afford one, go for the extra RAM. Doubling the RAM is cheaper than doubling the storage, and 8GB makes all applications feel more responsive. Neither the RAM nor the internal storage can be upgraded on the Air after you have bought it, but 128GB is still plenty and it’s quite straightforward to connect an external hard disk.
MacBook Airs can’t be upgraded for RAM and storage after you’ve bought them.
