First off, if you found this review helpful in your decision-making, please click on the helpful button so this review may help others in their decision-making process.Bought this to upgrade the storage space of my 2DS systems, which I dont regret. It not only increased my space, but after doing a bit of research, found out that it decreased my home screen load time and system settings options page, which was very slight, but noticeable. The 2DS systems come with a stock 4GB SD card (pictured), so this is about 8 of these cards in 1 card!! The other photos show the amount of space left in the top screen, and the bottom screens show the average size of a full game (mario kart 7) and the average size of saved game files, which can vary in sizes, but are not usually as large as the size of a full game download. After doing some math (calculator!!), you would max the card out at about 40 or so games (depending on the sizes of the games), which would be full game downloads, not the games you have a physical copy of. I personally prefer to have all my nintendo related games in a physical copy and the only two game series that are interesting to me is the fire emblem series and pokemon series, so this is probably overkill for me, but just in case there ARE any downloads that interest me, I will not have to worry if I have enough space or not.BEWARE!!! When upgrading any electronic, do research on the process of transfering and backing up your data. The last thing you want is something to go wrong during that process and all your saved game files (video games/ systems/ computers) or all of your contacts, photos and other essential data (phone/ tablet) gets erased and there is no way to get them back!!!
