FAT32 supports individual files up to a maximum of 4 GB (which is also why many cameras break up their video files into chunks that are 4 GB or less in a process known as chaptering). It only takes a minute to sign up. For those that have a range, its because that spec can be implemented as half duplex or full duplexbasically how many lanes are used for read/write operations. rather than limitations of the data interface which I believe is almost identical.

With many devices, being able to get a lot of data on or off the card quickly is a crucial function that the memory card has to be able to keep up with. Given two memory cards of the same capacity and same class, the only technical difference I know is that micro SD cards work on any device, thanks to the adapter, while Macro SDs will work only in devices with a Macro SD slot. And some much older devices will only work with SD. Some types of speed are more important to particular uses, while others matter more in different types of devices. But if youre buying a memory card for a gaming device like a Nintendo Switch or a smartphone or some other kind of device that runs apps and uses SD or microSD memory cards, the A rating is designed as a guide for what cards are best suited to that kind of use.
