When buying a laptop, one of the most important decisions you have to make is figuring out how much internal storage you need. Depending on the amount, it can drive up the price of the laptop considerably. For instance, Apple’s latest MacBook Air can be configured with either 256GB or 512GB of internal storage, and if you get the higher-end model that’s going to cost you an extra $200 — that’s a lot. Microsoft’s Surface Laptops, meanwhile, come in 128GB, 256GB, 512GB, and 1TB varieties. How much do you really need? There is no perfect answer, of course. But there are some handy rules of thumb and wrinkles to know about.
