It's important to pay attention to the specifications of the memory card depending on what you will use it for. A1 is suitable for most things, such as cameras and general storage. A2 is better for file transfers or continuous recording and can handle more read/write operations over the card's lifespan. M.nu recommends cards with A2 class for running operating systems on Raspberry Pi, but in most other situations, A1 works just as well.
