SanDisk512GB 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.

Nothing better than having a super reliable SD card like a Sandisk Micro SD card! I've never/ever had one corrupted on me, so I'm able to retrieve ALL my data from my Dashcam (which is what I use this specific 256 GB for). I'm able to record in the highest resolution setting flawlessly without any stutters or jams, mishaps or failures.I have hundreds of hours of recording using this because I constantly have files being looped over and over while driving so I can protect myself, or at least FEEL like I have extra eyes watching in the event something were to happen. I can TOTALLY rely on this brand (Sandisk) for pure 100% reliability.The price? Not bad, can't go wrong and a real great investment too. :)Thank you for reading my review. :)

This is a great product have used this brand for years however had to return because in my Cosmo 3 camera it did not work. I did go ahead a buy another scan disk however I had to go with the extreme. Seller was fine and in the future I would order from them.

It has proven to be an excellent choice for my storage needs. With read speeds up to 190MB/s and write speeds up to 130MB/s, it handles 4K and 5K video recording seamlessly, making it ideal for my action camera and drone. The A2 rating ensures smooth app performance, and the card’s durability features—waterproof, shockproof, and temperature-resistant—provide peace of mind during outdoor shoots. The included adapter adds versatility for use with various devices. Overall, this card offers a perfect balance of speed, capacity, and reliability.

Replaced the old sandisk ultra with this extreme and it's a world of differentsMy photos actually load on my phone now , with the old card only a few would load and it would seem to stop reading so I formatted this on to me phone and copied from the old and now I can even transfer to the card 1000 times faster than the old one. I'll be getting another one for my wife's phone soon

Just what we expected. This card was a better price point than some others of the same storage amount. However it arrived 3 days later than it said it would so too late for our vacation. I may end up returning it because we had to buy another somewhere else. Too bad as this is a good card.

This is an excellent storage card for my Mac Computers. Once upon a time, one could easily upgrade the storage chips and RAM cards on the motherboards. But Apple did away with that feature long ago. This fast sdcx is highly convenient and reliable. And with a proper card holder, it stays safely tucked inside my Mac laptops.

Awesome fast memory. These are usually the only sd cards I'll buy. Not too expensive like a Sams@@g, but just as fast and reliable.
