SanDisk 2TB Extreme microSDXC UHS-I Memory Card with Adapter - Up to 240MB/s, C10, U3, V30, 4K, 5K, A2, Micro SD Card- SDSQXAV-2T00-GN6MA

This card is everything I needed and more. I’ve tested it thoroughly in both my Steam Deck and Nintendo Switch, and it performs perfectly—no lag, no crashes, no issues with read/write speeds. Games load fast, updates install quickly, and large files transfer without any hiccups. The 2TB capacity is an absolute game-changer for anyone running a big emulation library or downloading tons of games digitally. I’ve filled this with hundreds of gigabytes worth of games, videos, and apps, and it hasn’t skipped a beat. It’s rated up to 240MB/s, and it holds up well even under heavy use. I also appreciate that it comes with an SD adapter for easy use in laptops and card readers. I’ve used it for 4K video capture too, and it hasn’t dropped a single frame. It's V30 and A2 rated, which means it's optimized for both video recording and fast app performance. Highly recommend this to anyone looking for high-capacity, high-speed, reliable storage—especially for gaming handhelds like the Steam Deck or Switch. I’ll definitely be buying another one in the future.

It's compatible and works well with my Samsung Galaxy S11 Ultra. My tablet automatically detected the small microSD card as soon as I plugged it in the slot. The capacity is true to its seller's description here, so memory quality is good. Let's see how fares after a few months.

Works great on my "Nintendo Switch", so I bought another one, thinking it would work on my Switch 2. Negative, it does not work on my Switch 2 at all. Thus, I now have 4 tb of storage for my switch 1. This honestly is not a bad situation to be in for me, since I have at least 2 tb of cloud games on my Switch that need a card to sit on. However, I can not respect the price for it, as it will be relegated to outdated tech. This has nothing to do with the card or the price of the card. Just being stuck using it for the Original Switch invalidates the value of the use case of this card for me.

Great quality, I usually buy the more friendly cost memory cards had no idea what I have been missing. This is some much quicker pulling up files, downloading or uploading too. And I haven’t experienced one corrupt file like I have plenty of times with those value memory cards

Lots of space and works well with my Legion Go S.

Lot of storage which is very good, but when using on a steam deck the download speeds are not consistent. Occasionally it will throttle the speed, thus has only happened once to me but it is worth noting

Device: SteamDeck LCD Model Completely works for my device, downloads and runs my games perfectly fine. The only issues I encountered were the size of the chip it’s kind of a tight fit but it works just be careful and formatting which could just be my device I had to restart it twice and format it twice for it to work so take that with a grain of salt!

Feels like a scam, supposedly delivery was "attempted" twice to my address and this card has not been delivered. Card arrived late, seems to work and be of acceptable quality.
