SanDisk Ultra 128GB microSDXC Memory Card + SD Adapter with A1 App Performance up to 100MB/s, Class 10, U1 - Amazon exclusive packaging

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.

Arrived quickly and well packaged, the package design has changed recently. I have been buying these SanDisk Ultra Cards for a few years now in various sizes more so now that they have reduced in price, this is for most SSD's not just the micro ones as these are. I do a little bit of retro gaming and use these cards for my home made games consoles as per pictures I have recently made a mini megadrive this is alongside the mini PS1 I have bought from Amazon. These cards are class 10 and perfect for the raspberry Pi that fits inside these cases. These cards support mobile phones, camera's, tablets, laptops etc, incidentally I have just put one of these in one of my friends laptops that was struggling for storage. These cards come in various sizes so you will have to see what limits your device will support before you buy. I have not encountered a problem with them yet. Look me up on you tube if you are thinking of doing something similar, I have a whole series on retro gaming and also check out my builds lists on here, I have a page with various PC budget builds and components and also do vine reviews. 👍

Works as intended, good quality.

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 :)

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

This product is very cheap and reliable. I’ve bought several Sandisk micro sd cards in the past and they’re a fantastic option when taking the price and eliability into consideration. Not only that but they always come with an sd converter for use in your laptop/pc to save you having to go and buy one separately. Perfect in every way. Arrived swiftly and the only downside was that it came in generic packaging which didn’t affect the product as it was sealed non the less. I think this may have been because it was bought outside the uk possibly but even then it works amazingly. The seller was great too and didn’t have to contact them regarding the product. Reccomend t LG is purchase if you need a storage device for your mobile phone. NOTE: these aren’t used with iPhones.

I bought the SanDisk Ultra 16GB microSDXC card with the SD adapter when it was £5.99, which felt like good value. It now seems to be £19.99, which is quite a jump. It does what you’d expect – decent transfer speeds up to 100MB/s and it works fine for photos, videos and general storage. The A1 rating helps apps load a bit quicker, and the U1/Class 10 rating is fine for Full HD recording. With Amazon Prime you also get free delivery and easy 30-day returns, which is reassuring if anything goes wrong.

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.

Gewohnt gute Qualität von SanDisk. Ich habe schon einige Speicherkarten für diverse Endgeräte gekauft (Camcorder, Fotoapparat, Actioncam etc.). Aufgrund der guten Preis/Leistung oft von SanDisk. Dieser Kauf kommt in einem Surface Pro zum Einsatz. In meinem Fall war die Geschwindigkeit hier eher zweitrangig, es ging in erster Linie um die Speichergröße und den aufgerufenen Preis. Daher reichte mir eine UHS-1 Karte völlig aus und der Aufpreis zu den schnelleren UHS-2 Karten konnte in meinem Fall gespart werden. Da die Karte als reine Speichererweiterung eingesetzt wird (z.B. für Bilder), läuft bisher auch kein Systemwichtiges Tool, Programm oder Microsoft selbst von der Speicherkarte. Ich konnte bisher keinen negativen Punkt bei meiner Verwendung erkennen. Sicherlich sehen Profi-Fotografen mit besonderen Kameras die große Datenmengen verarbeiten diesen Punkt etwas anders. Denn je langsamer die Schreibgeschwindigkeit ist, desto länger muss der Fotograf warten bis ein neues Bild geschossen werden kann. Der Speichervorgang benötigt also etwas Zeit. Ich habe die gleiche Karte mit geringerem Speicherplatz in meiner Sony DSC-HX400V und mir fällt die Geschwindigkeit, zumindest beim „ich nenne es mal laienhaften Hobbyfotografieren“, nicht negativ auf. Es handelt sich aber bei der Kamera auch nicht um ein Top-Profigerät. Fazit: Es kommt also bei der Geschwindigkeit immer auf den geplanten Einsatz und den persönlichen Anspruch an. Die Speicherkarte wurde im Surface Pro sofort erkannt und es gab keine Probleme. Ich bewerte die Karte als rundum solide mit einer aktuell guten Preis-/ Leistung.

Habitué de la marque dans la référence "Extreme" sur des versions de capacité supérieure (je suis photographe et opérateur de prises de vues aériennes et les utilise essentiellement en enregistrement vidéo en 4K sur mes drones), j'ai achetée celles-ci (5 en 16Go compte tenu de leur faible prix) afin de les intégrer à mes caméras de vidéo-surveillance et assurer ainsi des enregistrements supplémentaires de sécurité. Livrées et installées dans la foulée le 18 décembre (nous sommes le 4 janvier à l'instant où j'écris ces lignes), j'ai voulu attendre un peu de voir leur comportement sur des sollicitations 24h/24 en afin d'être le plus objectif possible. Ma foi... force est de constater que les 5 exemplaires en ma possession font parfaitement leur job sur 17 jours d'enregistrements continus (soit 408 heures H24) dans des conditions climatiques variables allant du très sec au très humide et pour une plage de températures allant du positif au négatif. En outre sur les 5 cartes que je viens de tester une à une il est à noter qu'aucune d'elles ne comporte le moindre fichier corrompu. À ce sujet j'ai pu lire dans certains commentaires que certains se plaignent de la corruption de fichiers photos ; par expérience (encore une fois c'est mon métier) cela peut effectivement arriver. Cela étant quand bien même personne n'est à l'abri d'avoir la malchance de tomber sur une carte défectueuse, ce problème n'est pas nécessairement inhérent aux cartes (qu'elles soient MicroSD, SD, ou autres) et peut tout à fait parvenir d'un problème firmware ou hardware des appareillages dans lesquels elle est utilisée. Pour simple exemple un de mes confrères avait ce type de soucis de manière assez récurrente sur des SD similaires à celles que j'utilise en reportage ; les siennes "plantaient" dans une période comprise entre 3 et 6 mois alors que certaines des miennes avaient déjà plus de 3 ans (et pour certaines déjà quelques 430.000 clichés à leur actif) sans jamais avoir à déplorer le moindre plantage. Le problème a très simplement été résolu par une mise à jour du firmware de son boîtier qui semblait envoyer à ses cartes des informations parfois un peu "olé olé"... Bref, je ne dis pas que les SanDisk sont les meilleures du monde ni que - comme toutes les autres marques d'ailleurs - on est certain que l'exemplaire utilisé sera exempt de défauts ; je dis simplement - par expérience - que l'on a bien souvent tendance à incriminer la qualité d'une carte en cas de problème alors que la cause n'est pas nécessairement là et qu'il vaut la peine de s'y pencher.

Tenia que comprar dos trajetas, en un primer momento opté por ir a media mark pero el modelo que tenian no era el que estaba buscando por lo cual, pa casita que llueve, me dijeron que a unas malas la podia pedir por la web y luego pasar a recogerla...Bla, Bla, Bla... para que la voy a pedir por la web e ir a recogerla cuando la puedo pedir por la web y me la traen a casa. Y bueno llegados a este punto solo deciros que es una tarjeta micro SD bien de precio, ni cara ni barata, en la linea ScanDisk por que es una buena marca, y hasta la fecha ningun tipo de problema, procesa bien los datos en cuanto a rapidez y no se traba, hablamos que una de ellas esta puesta en un samsung galxy s7 haciendo tambien de pendrive en casa por lo que muy contenta y satisfecha

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.

The memory card is not working; it won't turn on.
