SanDisk Ultra 16GB microSDHC Memory Card + SD Adapter with A1 App Performance up to 98MB/s, Class 10, U1 - Amazon exclusive packaging

Used this in a phone, dash cam, and tablet—handles app installs, 4K video, and large file transfers without breaking a sweat. Speeds are solid for a Class 10 card, and it’s never glitched or corrupted data. Plug it in, format it, and it just works. Build quality’s decent—feels sturdy for a micro card, and it’s survived heat, cold, and a few drops. A1 rating means apps load quick and run smooth, especially on Android. Perfect for drivers, streamers, or anyone needing serious storage without the bulk. Minor gripe: not the fastest for pro-level video editing, but more than enough for everyday use. 👍 Pros ✅ Fast read speeds (up to 100MB/s) for smooth playback and transfers ✅ A1-rated for app performance—great for Android users ✅ Reliable in phones, dash cams, and tablets ✅ Huge 256GB capacity in a tiny form ✅ Durable and heat-resistant 👎 Cons ❌ Not ideal for high-end 4K video editing workflows ❌ No included adapter (depends on seller) ❌ Write speeds slower than top-tier U3 cards

Works as intended, good quality.

Exactly as described and fast delivery at a good price. Really, what more could you ask for.

Reliable but could/ should be Faster? As always I buy a SanDisk Authentic card from Amazon only not any 3rd party sellers as it's too big a risk since SD cards are probably the most Faked / Copied things on Earth ;) I bought the 200Gb MicroSd version which is supposedly a Class 10. It's certainly not going to win any prizes on the speed stakes that's for sure... However I had bought 1 of these cards a few months back & it was supposedly the exact same 200Gb MicroSd class 10 card & my older 1 (which was again bought from Amazon Direct no 3rd party seller) is significantly faster at writing data to & ever so slightly faster at reading date. I don't know if SanDisk now make x2 models of the 200Gb MicroSd Class 10 U1 cards now or what but if your expecting a really quick write speed & more importantly need that fast write speed maybe look elsewhere for quicker options IMHO. The Card gets used in a device which doesn't require a speedy write speed so I wasn't that bothered & it's definitely OK no problem with it & it's 200Gb of storage space is handy for sure. So I guess overall cause of its cheap price these days that it might be the current best Bang per Buck in the 200/ 256 gb range of cards on offer at the present time. Pros: Reliable SanDisk Quality with lifetime warranty I belive + Decent read speed. Cons: Disappointing Write Speeds as a class 10 U1 card should deliver better IMHO. Recommended though due to the Pros far out weighing the 1 Con :)

I bought one of these from Amazon as a replacement after being sent a fake one from eBay. The one that arrived from Amazon is 100% legit and has worked in my Nintendo Switch perfectly with no issues whatsoever so from me it's 5 stars... however... Looking through other reviews, reading people's descriptions and seeing the pics people have posted I can confirm that people are recieving the same fake cards from Amazon that I recieved through eBay. I don't think this is on purpose by the seller as mine was legit so I think these fake ones have slipped through at some point. Some things to look out for if you do order a card and want to check the legitimacy of it: 1) The packaging they sent the fake card to me in is a white cardboard sleeve with a phone on the front next to the green android robot (an example photo has been uploaded by another customer in their review for reference). Look thoroughly at the image of the phone. Is it blurry? If so then it's fake. 2) look at the card itself. Does the grey part of the card look really dark? And does the red part look like a painted layer on top of the grey part leaving a nanometre of a bump between both colours? If the answer is yes, it's a fake. 3) is the card a tight fit? Legit cards sit perfectly flush and will never have any fitting or seating problems. Those that do are usually fake. 4) how much data can you fit on the card? Can you store a few gigs of data onto the card but after a certain point does it straight up refuse to transfer any more? If yes then the chances are it's fake. Sometimes there are manufacturer faults in legit cards where they have faulty sectors straight out of the box but these are rare so it's best to assume it's fake. Further tests would need to be made to properly identify it. What these scammers do is they use smaller sized cards and hack the software to read that it's a bigger size than it actually is. This was the case for my original card from eBay. The card would store 4gbs of data and then would "fail" despite saying i have over 100 gbs remaining. I first did an error test on HDtune to see whether it hard any bad sectors (it passed so it was fine there) then I did a read and write test which identified that I had in fact a 4gb card disguised as a 128gb card. Just a few things to check when purchasing cards online to help those who may not know about this stuff and to help them from possibly getting scammed. Hopefully this all helps.

nice and cheap

Bought for garmin 340 sat nav. Just plugged in and all was good. No formatting required. Downloaded the European maps no problem.

My 128GB MicroSD card was running low on space on the Nintendo Switch, so I needed an alternative. 256GB cards are still way too much but this SanDisk Ultra 200GB microSDXC was a great price and perfect for my needs. Moving everything over from one card to the other was simple. the card was pre-formatted to Ex-Fat which the Switch can use, and I just needed to move the folder on the root of the card from the 128GB to the 200GB on my PC. The read/write speeds have been perfect since installing the new card on the Switch, no issues with slow loading games and plenty more space to play with. Note: The SanDisk Ultra 200GB microSDXC was bought direct from Amazon themselves, you do need to be careful with third parties selling these.

Bonjour, j'ai acheté cette carte car j'avais besoin d'une nouvelle carte microSD pour la tablette de mon papa (une Galaxy Tab4 supportant les microSD jusqu'à 64Go). J'avais l'année dernière acheté et testé la version précédente, je précise la dernière version de celle-ci (avec des débits beaucoup plus rapides...) car elle avait le même intitulé sauf indiquée (nouvelle version), à l'époque je l'avais testé sur mon Mac, c'est ainsi que j'avais remarqué que mon lecteur SD interne était beaucoup moins performant que mon lecteur USB3: https://www.amazon.fr/gp/customer-reviews/R31V0STA6Y383R/ref=cm_cr_srp_d_rvw_ttl?ie=UTF8&ASIN=B013UDL58E Pour faire simple, cette Ultra A1 (testée ici avec une capacité de 64Go) est très performante, à la fois en lecture mais également en écriture mais au final très proche (pour ne pas dire plus...) de la version précédente. J'ai cru comprendre que les cartes A1 étaient intéressantes sur Android enfin d'obtenir de meilleures performances avec les applications installées dessus, cela est valable pour une version d'Android récente (v7 mini si je ne dis pas de bêtises). "Si les cartes mémoire au format MicroSD de nos smartphones et tablettes tactiles peuvent stocker des photos, des musiques et des vidéos, elles ont aussi la possibilité d’accueillir des applications. Avec les dernières moutures d’Android, le formatage permet même de rendre la chose totalement transparente, en fusionnant la mémoire initiale de l’appareil et la mémoire additionnelle. Maintenant, encore faut-il que les performances soient suffisantes pour permettre à des applications de fonctionner correctement. La SD Association vient d’introduire une nouvelle certification A1 (ou A1 App Performance, dans sa version longue) qui sera apposée sur le produit et son packaging afin de permettre à l’acheteur de savoir si la carte mémoire devant lui permettra de charger des applications dans de bonnes conditions. Les critères pour prétendre à cette certification A1 sont des débits d'au moins 10 Mo/s en lecture/écriture séquentielle, 500 IOPS en écriture aléatoire et 1 500 IOPS en lecture aléatoire." Articlé trouvé sur Generation-NT.com Pour faire court, cette carte est très performante, surtout pour cette gamme de prix, payé dans les 24 euros en version 64Go. Vous trouvez quelques photos des tests de performances réalisés sur différentes configurations (avec le logiciel CrystalDiskMark 5.2.2 x64), mais toujours avec mon Pc portable Dell Precision 5510, je suis passé à la fois avec le lecteur de carte SD intégré (très rapide) du Pc portable (avec l'adaptateur performant microSD vers SD livré avec la carte), mais également mon lecteur USB3 Transcend TS-RDF8K, la carte a été testé sur l'entrée microSD du lecteur mais également sur l'entrée SD du lecteur (toujours avec l'adaptateur livré avec la carte). Dans tous les cas, j'ai réalisé des transferts de 100Mo et 500Mo. L'ancienne et nouvelle carte A1 sont très proches en terme de performances, s'il y a une grosse différence de prix, prenez la moins onéreuse... En espérant que mon commentaire vous aura été utile, n'hésitez pas à cliquer sur OUI si tel était le cas. Cordialement

Llevo mucho tiempo utilizando tarjetas Micro SD tanto para móviles, cámaras, etc. siempre lo primero que me fijo cuando compro una tarjeta micro SD, primero la capacidad ya que con los móviles ahora de última tecnología, la resolución de las fotografías cada vez es mayor y cada vez necesitamos más espacio, pero lo más importante en lo que suelo fijarme es en la velocidad de transferencia, esta tarjeta no es de las más rápidas, pero la velocidad de transferencia está bastante bien alcanza aproximadamente los 100 Mb por segundo según fabricante, aunque en pruebas que realizado me da algo menos. Decir que el precio que tiene para las prestaciones y la calidad que da está muy bien, en relación con otras marcas. La he probado en varios teléfonos y todos me ha funcionado sin ningún problema, había leído en algunos comentarios que parecía que daba problemas de que no reconocía la tarjeta, si recomiendo hacerle un formateo si no la reconoce desde el terminal, pero como ya he dicho no he tenido ese problema. Al ser de clase 10 graba y reproduce vídeos Full HD. No me ha gustado mucho, el embalaje en el que viene, da la sensación de ser un poco cutre, me imagino que para poder llegar a eso precios se debe recortar de donde se pueda. Desde que tuve problemas con una tarjeta que compre sin ser de marca llego a calentarse de tal manera que casi me estropea el teléfono y desde entonces sólo estoy utilizando esta marca me ha ido bien en mis anteriores teléfonos y hasta ahora no he tenido ningún problema, pero esto es como todo, ya se sabe componentes electrónicos, suelen fallar cuando uno menos se lo espera, por eso recomiendo siempre tener otra copia de seguridad, en otro formato, llámese nube, NAS etc. Funciona perfectamente y la velocidad de almacenamiento tratamiento y visionado de archivos es bastante rápida recomiendo tanto por la calidad, garantía, que da y el precio que tiene. Muchas gracias por haber leído mi revisión y espero que te allá sido útil, y si te ha quedado alguna duda, no dudes en preguntar.

Ottima ormai la uso nel telefono da più di 5 anni e non ha mai avuto problemi, super capiente di spazio e veloce ad essere letta quando si avvia il telefono

Billig

Pongo solo 3 estrellas en el precio, porque a los 3 días de comprarla, salió las misma marca de tarjetas de 128 GB por 18 de euros, la he comprado para un teléfono, quería ampliar la memoria interna del teléfono mediante root y la aplicación LINK2SD, que se utiliza para estos casos, para instalar todas las aplicaciones en la micro SD, de momento el teléfono va bien, lanza las aplicaciones de forma fluida sin lags, hay que tener encuenta que estás micros SD, vienen con una velocidad de escritura y lectura aseptable para que funcionen en dispositivos Android.
