Thin, light, durable. Thank you, flash storage

Even at less than an inch thin, MacBook Air sets a pretty high standard - by making flash storage standard. Flash chips are very small, allowing MacBook Air to be incredibly thin and light. Flash is also solid state, meaning there are no moving parts. Which makes it reliable, durable, and quiet. And because we place the flash chips directly on the logic board, they take up much less space - about 90 percent less, in fact. That creates room for other important things, like a bigger battery. So you have a notebook that weighs almost nothing and runs for hours on a single charge. That's mobility mastered.
