Although the Switch has the capacity to support micro SD cards with capacities up to 2 GB of memory, these are not yet available for purchase by consumers. However, that said, there are now some great and cost effective Nintendo Switch external flash memory cards for sale which will enable you, at least, to, in most cases, double what the console itself can accept. These cards have been manufactured by several companies, most notably SanDisk and Intellicore. The cards themselves come in a wide variety of capacities, but most tend to be around the same size and are available in a fairly limited number of formats.
It should be noted that although the Nintendo Switch supports micro SD memory cards, it is not compatible with all micro SD memory cards. This is why it is recommended that you do your own research as to which particular card formats are compatible. The main difference between the various formats and capacities offered by micro SD memory cards is the bit rate. The higher the bit rate of the card, the faster the transfer rates of the images and videos, which means that they will be ready to play on the Nintendo Switch as soon as you download them onto your system.
Not only that, but it is also possible for users of Nintendo Switch to save files directly to their micro SD memory cards via their consoles, meaning that they no longer need to download games or the like to be able to save their files. What’s more, the majority of micro SD memory cards manufactured by SanDisk and other manufacturers can also be formatted by the user, making them even more attractive. The cost of the cards themselves remains quite reasonable, especially when you consider the benefits of being able to store a great deal of data on a tiny memory card. So if you are looking for a way to expand your games library on Nintendo Switch, consider downloading your saved games directly from your micro SD memory card!
