Quality, name brand memory chip for my phone. Works great and is a reliable brand.
Needed a new memory card for my Moto G phone. This works great, was easy to install, and allows me to take all the videos I want of my dog. Lots of memory for the price from a reliable brand, exactly what I was looking for.

CONTINUOUS WRITES AND READS TESTED
I bought this SanDisk 256GB microSD card to use in my Raspberry Pi, and I’ll be honest—I fully expected it to die within a few months. Why? Because I’m using it to constantly record Tesla Sentry Mode footage, meaning it gets written to every single day, nonstop. But here we are, six months later, and this little card is still holding up like a champ. No corrupted files, no slowdowns—just reliable performance. What It Does Well: Even with continuous write cycles, this thing hasn’t slowed down or failed. Perfect for dashcams, security cameras, or Raspberry Pi projects. Holds a ton of footage before it starts overwriting. I can go back days to review recordings if needed. Heat, cold, constant writing—no issues so far. This isn’t my first SanDisk card, and they’ve always been solid for me. One Small Thing to Keep in Mind: Like all microSD cards, it’s best to format it properly before use, especially for high-write applications. Some devices (like my Tesla) work better when you use the exFAT format instead of FAT32. Just something to check before you get rolling. Final Thoughts: If you need a reliable microSD card for constant use, this one is a great bet. I wouldn’t hesitate to buy another for my other gadgets. Just make sure to pair it with a good reader or adapter if you’re moving large files—it’s fast

No more storage worries
With 256GB, my smartphone now holds tons of photos and video without that dreaded “storage full” alert. The up-to 150MB/s read speed shows—after switching some apps onto this card the load-times improved noticeably. I also used it in my Nintendo Switch (older version) and the “Preparing data” screen during game load-up was significantly shorter. The included SD adapter makes transferring files via PC a breeze. If there’s any minor gripe, it’s that the initial format took a bit of time, and the tiny card means you need to handle it carefully when inserting/removing. Overall, very reliable and versatile.

Compré la SanDisk Ultra Micro SDXC de 256 GB con adaptador SD para ampliar el almacenamiento de mi móvil y usarla también en una cámara compacta. En general funciona bien, pero después de varias semanas de uso tengo sensaciones mixtas. Lo que sí me gustó - Velocidad adecuada para el día a día: Para transferir fotos, vídeos en 1080p y archivos grandes, la velocidad es razonable. No es la más rápida del mercado, pero cumple sin problemas para un uso normal. - Buena compatibilidad: La he probado en móvil, portátil, cámara y hasta en una Nintendo Switch, y en todos los casos la reconoció sin complicaciones. - Capacidad real cercana a lo anunciado: Después de formatearla, la capacidad útil es la esperada para una tarjeta de 256 GB. - El adaptador SD funciona bien: No es de los más robustos, pero permite transferir archivos al ordenador sin necesidad de un lector adicional. Lo que no me convenció - Velocidad irregular en ciertos momentos: En transferencias largas (más de 20–30 GB), la velocidad cae bastante después de los primeros minutos. No es dramático, pero sí se nota si trabajas con muchos archivos. - No ideal para grabación 4K: Aunque SanDisk la promociona como rápida, en mi cámara algunas grabaciones en 4K dieron pequeños tirones. Para Full HD va perfecta, pero para 4K no la recomendaría. - El adaptador se siente frágil: Funciona, pero el plástico es muy ligero y da la sensación de que podría romperse con un mal movimiento. - Precio algo elevado según la temporada: Dependiendo del día, hay alternativas con velocidades superiores por un precio similar. Conclusión Es una tarjeta fiable para uso general, perfecta para móviles, tablets, consolas y cámaras que graben en Full HD. Sin embargo, si tu prioridad es la velocidad constante o grabar vídeo 4K sin interrupciones, puede quedarse corta. Aun así, para la mayoría de usuarios es una opción sólida y práctica.

SanDisk microSDs are always reliable and never have let me down. I buy them often and haven't had one fail on me in the years of buying them. The quality is top tier. The read and write speeds are great for moving files on and off of it. I use these for things like photos and videos for my camera as well as for games on my Steam Deck and Switch.
