Memory cards are some of the oldest type of storage devices. They use flash memory to save data and that means no mechanical parts. Which is also the reason why they can be made so small and why they are still so popular after all the years. Plus they are still used by digital cameras and phones as well. Which has also driven the development of different types and sizes. There are even 1TB MicroSD cards available now!
But unfortunately computer brands have kind of forgotten about it. Or they have chosen to ignore it as most new computers no longer have memory card readers. And if they do, then it’s usually only for MicroSD cards. Which is somewhat problematic as cameras still use the good old SD standard. That’s why there are brands that have started creating memory card readers as well. Unfortunately the quality varies quite a bit. Which is why I try to review the most popular ones firsthand and provide my opinion.
