When you go to purchase an SD memory card for your camera, you’re faced with a confusing collection of acronyms and jargon. Here’s a breakdown of what the symbols and terminology mean so you can order the right one for your camera and situation.
A card’s capacity is measured in gigabytes, such as 16GB or 64GB. You may be tempted to get the highest capacity you can afford, but hold on—many photographers recommend using your money to buy multiple lower-capacity (and therefore lower-cost) cards instead of one or two high-capacity cards. Shooting across four 32GB cards is better than storing everything on a single 128GB card in the event that a card gets damaged, lost, or stolen.
