256GB Extreme microSDXC UHS-I Memory Card with Adapter - Up to 190MB/s, C10, U3, V30, 4K, 5K, A2, Micro SD Card - SDSQXAV-256G-GN6MA

I bought this memory card for my Samsung tablet. It fits perfectly, and is recognized by the machine. As far as I can detect, it works perfectly. It was a very reasonable price for a quality chip. Because it is so small, the opening in the tablet was a little tricky to deal with, but installation was still easy. I would recommend this card for lots of extra memory.

I ordered it primarily for my insta360x5. Worked right away, no slow card warning and no formatting needed. I'm quickly finding out i need more storage 😅. I think it was quite affordable, and good for any kind of shot the 360 throws at it including 8k. Can't wait to see how it reliable it will be for the next couple of months.

No problems with this. Seems reliable. Larger and faster than the old worn-out card it replaced.

The SanDisk 256GB Extreme microSDXC worked perfectly for my older Samsung tablet. Installation was quick and easy, and the tablet recognized it immediately without any issues

Sandisk quality. I use these in all my cameras and have never had a failure period. I only trust these. They are fast and in every capacity I need. These were also at a great price.

The SanDisk 256GB Extreme microSDXC performs very well, with fast read/write speeds that handle 4K and 5K video smoothly. The included adapter is handy, and the large 256GB capacity is great for cameras, drones, and other devices. My only drawback is that it’s a bit expensive compared to similar cards, but the quality and reliability make it worth considering. Overall, a high-performance and dependable microSD card, just slightly pricey.

I am a big fan of SanDisk. They are my "go to" brand when purchasing flash memory devices. When I first started purchasing flash memory devices I tried a variety of brands. I learned the hard way that some less expensive devices just didn't last, lost data, or did not always read like they should. Once I purchased SanDisk products I just didn't have problems with them. I have purchased SanDisk SD cards, micro SD cards, and thumb drives. My experiences have all been positive. I still have some from several years back that continue to function well. Most important to me is that I find that they are at a nice price point and, as mentioned, work well over time. I use their micro SD cards for my phones (those that still accept them), my security cameras, and my dash cams. I use this specific series, "Extreme" for dash cams. I use the "Ultra" series for my phones and security cameras. My apologies but I am not an expert at doing bench tests on these products. My only experience is actual use. So my gauge of quality is, "Do they work when I need them to?" Unfortunately, the only measure of this is when they go bad, which does not seem to happen with how I use them. As mentioned, I just don't have the issues I had when I purchased lower priced (quality?) devices. I am sure there are some much more knowledgeable reviewers who can report on transfer speed. It would be great to see some of these reports because I have been wondering lately if some of the "higher end" series of micro SD cards are worth the extra price. When I was looking for dash cam micro SD cards, I did a little research and found several reviews that included the SanDisk "Extreme" so I did step up and paid the extra for the "Extreme" series. I also know that I have never had any issues with formatting a SanDisk card. Most of the micro SD cards I order come with an SD card reader. That is nice even though I now have several. That said, I saw that SanDisk also makes a "USB-A" micro SD card reader. The micro SD card loads from the end rather than the side like many of the card readers. I may end up trying one of those at some point. Or, wait to see if they come out with a "USB-C" version. Recommend: YES Questions: Just wondering if there is really that much difference between the various "series" that SanDisk has for their micro SD cards.

I bought these cards for my action cam and insta360, and it handled everything I threw at it. The transfer speeds are super fast, so moving videos and photos to my computer is way easier than with my old card, and it recorded 4K footage flawlessly even on longer shoots. Really reliable and high quality. Definitely recommend if you need a fast, solid microSD card!

Acheté en deux exemplaires, très bonne carte SD, rapide et fiable. Utilisée dans un lecteur SanDisk USB 3.2 Gen 1, elle atteint en écriture soutenue 86–87 Mo/s, ce qui est parfaitement cohérent avec les 90 Mo/s annoncés. Aucun ralentissement, aucun problème de compatibilité. Utilisées pour des OS sur Raspberry Pi et Jetson Nano et pour stocker du flux webcam en direct. Aucun souci, très bon débit. Testée sur Linux avec dd en écriture (fichier de 500 MiB puis 5 GiB depuis /dev/urandom, conv=fdatasync), la carte atteint 86,8 Mo/s constants en écriture. Pas de buffer temporaire, pas de throttling : les débits sont stables sur toute la durée. Le contrôleur gère bien les gros fichiers. Les valeurs de lecture n’ont pas été testées ici, mais la promesse de 190 Mo/s sera de toute façon liée à des conditions optimales (QuickFlow™ activé + lecteur propriétaire SanDisk PRO). Pour une carte UHS-I V30, les performances sont quasiment maximales. Très bon choix pour un usage exigeant, y compris en 4K ou pour transfert de gros fichiers.

Bardzo dobra karta do Nintendo Switch Lite. Działa idealnie.

- Calidad/Precio: Si bien es cierto que bajo mi punto de vista, en gran parte el precio es debido a la marca, si observas las especificaciones estamos hablando de la gama alta, lo que hace al final que cómo resultado estés pagando por una calidad superior a un precio equitativo. - Aspecto: Compacta, viene con su adaptador SD y un código para descargar el RescuePro Deluxe, por si necesitas recuperar archivos en caso de emergencia. Todo bien presentado, como nos tiene acostumbrados SanDisk. - Satisfacción: 10/10. La tarjeta funciona rápido y sin errores, tanto en transferencia de archivos como en grabación continua de vídeo 4K. El rendimiento A2 también se nota al usarla con apps: todo va fluido y sin lags. ¿Lo recomiendo? Sí, sin ninguna duda, tengo claro que en caso de que deba realizar la compra de otra tarjeta Micro SD, esta es mi opción núm. 1. Estamos hablando de 1TB en una microSD, es una barbaridad, por mucho que te dediques a fotografiar o a grabar de forma extensa en altas resoluciones, tarda en llenarse está claro, eso genera muchísima libertad y comodidad a la hora de crear el contenido, en otras palabras: una tarjeta hecha para rendimiento profesional, en mi caso utilizada para la GoPro HERO Black 12, y tengo claro que podría traspasarla a la Sony ZV-1 en cualquier momento. El precio no es bajo, pero vale cada euro si necesitas espacio, velocidad y fiabilidad, esta tarjeta es una bestia. Ideal para creadores de contenido, fotógrafos, videógrafos o cualquiera que trabaje con archivos grandes.

Die microSDXC Speicherkarte von SanDisk ist super. Hohe Geschwindigkeit, zuverlässige Leistung und mit SD Adapter sehr flexibel nutzbar. Der Versand war zudem schnell und gut verpackt, insgesamt alles top.

Exactly what i needed and that stuff work very well for my phone!!
