SanDisk 512GB Extreme microSDXC UHS-I Memory Card with Adapter - Up to 190MB/s, C10, U3, V30, 4K, 5K, A2, Micro SD Card - SDSQXAV-512G-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.

I have been buy SanDisk for years and they never disappoint. All of their SD cards and USB drives have a great longevity and are always as fast as advertised. I always by the faster versions in the type I need for best performance. These work great in N SW1, Samsung phones and tablets (and probably other brands), Raspberry Pi, and anything else that needs a micro SD card.

Finally managed to set this Micro SDXC card as internal storage using ADB on my sis' pc since it isn't an option on my TCL A3 phone. Typing the commands for first time made me feel like a real hacker😊. Gotta say I'm loving the extra 128 GB to use on my Android phone, it's so handy. I am still suspicious as to if it might bug my phone out and destroy it tho. Still smooth sailing so far.

I used this SanDisk 1TB Extreme microSDXC with my GoPro during my recent trip to Nepal, and it performed flawlessly. From hiking in the mountains to capturing stunning 4K videos of the landscapes, this card kept up with everything. Fast, reliable, and with plenty of space for all my footage.

Plenty of storage and fast transfer speed. I use one in my insta360 X4 which helps hold lots of videos and one in my galaxy tablet for more space to hold my 360 videos for editing. Got them on sale and glad I did

I bought this to enable me to store movies to view on my Kindle Fire Max 11 without depleting the built in memory. It was well packaged in bubble wrap so damage was as good as alleviated during prep and transportation. My kindle recognised it straight away. I'd read in some other ratings that its best to set as portable storage, so I did the same even though I don't intend to remove it. I've used Sandisk products before without problems and so far this has not shown any either with readability and reliability. I've had it installed for less than a month only. Its giving 5 star performance. but can only give it 4 stars for now because it needs to maintain that for a lot longer than the couple of weeks I've been using it.

I picked this up for my DJI Mini 2, and it’s been rock solid. The picture quality is sharp, even when shooting in 4K. Design-wise, it’s compact and easy to handle, and it popped right in with no fuss. It’s super easy to use, reads and writes fast, and hasn’t failed once. The build feels durable, and it handles high-speed recording without a hitch. Great all-around performance—no complaints at all.

I use this to expand storage on a laptop by game on. I even installed games on it. The games do load a little bit slower, but I’m a patient man. I survived gaming on computers in the 80s and 90s, load times are still much better these days even if you’re on an SD card.
