    • Good memory card, good price
Capacity: 256GB Style: Fortnite Cuddle Team Leader
Good price for good expansion. Fits the switch, no issues reliable memory card.

    • Works great
Capacity: 1TB Style: Legend of Zelda
This memory card works great looks good I bought it for my legend of Zelda switch OLED just to keep the theme going, but as a 1TB memory card you only have 800 in something gig out of it. Now I have a 1TB giga stone for my games as well I know I know I have a lot of games for my switch, but the reason why I have them is to try different one terabyte to see which one is best value for your money and the gigastone is definitely better value for your money because I would have 900 in something gigs out of it and I’m hearing that there is even cheaper 1TB options on Amazon that is a third of the price of this one and even gives you more memory. No, I bought this again because I had the legend of Zelda OLED switch and I wanted to keep the theme going on it like I said earlier and the SanDisk works great, but there are better options out there and this is coming from somebody who owns a lot of Sandisk products no I don’t have any issues with it but it is a little upsetting when you spend almost 130 or 140 bucks on a memory card when I could’ve bought three for the price of one and got more memory or I could’ve got a giga stone memory card and had 40 bucks left over at the time of purchase but again this is still a good product and I’m sure that the longevity will be good and the performance seems to be doing very well. It is a little slower on loading when it’s full but once it’s going, it works really well and I have not had any issues with it yet and I have played probably about 30 games on it so far and no hiccups. Like I said it’s just a little slow switching in between games since I have it completely full I use the switches on board memory for the save data. But with my giga stone, I never had any issues with that and it never lagged in load time there were larger games that did take a little longer to load but for the most part, I never had a single problem and it worked great. My device would be do your research on a different memory card I recommend giga stone since they’re tried and true, but there are other options that are way more affordable but I do not know on longevity or performance. I do know that they work just don’t know if it’s going to be good enough to be playing switch games or high definition movies or photos or anything like that I don’t know if it’s 4K but if you are like me and just wanted to keep the theme going and don’t plan on switching out the memory card and just want to be a big nerd like myself, then yes by this thing it’s good it looks great. Love the little design on it , the artwork on the package is perfect and I would buy another one in a heartbeat just to have as a display and I would even buy another one just to use but I prefer performance over design and practicality over design like I said before I only bought this, just because it’s SanDisk and the design matches the system And it was the right memory size that I wanted so with all that being said, I would highly recommend looking somewhere else to purchase your memory card because losing almost 100 gig is kind of a big deal. This should be around 920 or 960 gig not 860 something as you know 100 gig can mean nine more games or maybe a little bit more but yes, I do know that you can only play one game at a time but I don’t want to waste time constantly downloading my digital games I want to download them and be done not the finishing game deleting it and then re-downloading at a later time just like physical copies I just wanted there to play whenever I feel like it so now I have to buy another memory card just to finish downloading the other 50 or so games that I have which I was going to have to do anyway, but I would just recommend buying something else ... show more

    • Adorable, Reliable, and HUGE Storage – Perfect for Any Switch Owner!
Capacity: 512GB Style: Animal Crossing Leaf
The media could not be loaded. As a longtime Nintendo Switch player and Animal Crossing fan, I couldn’t resist picking up this 512GB SanDisk microSDXC card in the Animal Crossing edition—and I’m so glad I did! Not only does it look adorable with the signature mint green color and leaf icon, but it also delivers exactly what I need: tons of space for all my games, DLC, screenshots, and videos. I’ve downloaded more than 20 full games so far (including some heavy ones like Breath of the Wild, Pokémon Violet, and Smash Bros.), and I still have plenty of room left. The load speeds are super fast—games launch quickly and I’ve never had any lag or corruption issues. Plus, the fact that it’s officially licensed by Nintendo gives me peace of mind that it's built for the Switch system. Whether you're a casual gamer or someone who has a growing digital game library, this SD card is a must-have. And the Animal Crossing design? Just the cherry on top 🍃 ✅ Pros: Massive 512GB capacity Fast, reliable performance Cute and unique design Officially licensed for Nintendo Switch If you're looking for storage that’s both functional and fun, I highly recommend this one! ... show more

    • Very reliable.
Capacity: 256GB Style: Super Mario Super Star
This microSD card is a very reliable, high-capacity option that works great for a mix of uses — 4K video, action cams, Android devices, and more. It's not the absolute bleeding-edge fastest card, but for the money, it's excellent. If you need something ultra-high write speed, you might go more “pro,” but for most users — this is more than good enough. ... show more

I bought this SanDisk 1TB microSDXC card to expand my Nintendo Switch storage, and it’s been an excellent choice. After more than 6 months of use, I haven’t had a single issue. The console recognizes it instantly, downloads are fast, and games run smoothly without delays. The massive storage is perfect for installing plenty of digital titles without worrying about space. Reliable, fast, and highly recommended for Switch owners. ... show more

Installed and worked as it should. Wish I would have gotten a 256G at least though, storage gets filled up so easy on these switches.

    • NOT compatible with the Switch 2
Capacity: 1TB Style: Legend of Zelda
Love the storage capacity. Have this in my OG switch. And I didn’t know this at the time, but apparently if you didn’t have enough storage, your games say they will take 8+ hours to download. Plugged this in and my game only took 30 minutes lol. Took off a star because this is NOT compatible with the Nintendo Switch 2 which was the main reason I bought it ... show more
