SanDisk256GB Extreme microSDXC UHS-I Memory Card with Adapter - Up to 190MB/s, C10, U3, V30, 4K, 5K, A2, Micro SD Card - SDSQXAV-256G-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.

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 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.

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.

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.

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.

Bought the two terabyte one, & it is fast & works well, literally have an operating system running off of it without any hiccups, flaws, nor delays.
