SanDiskExtreme 64 GB microSDXC Memory Card + SD Adapter up to 90 MB/s, Class 10, U3, V30

Got this for running games on my mobile. Works like a charm. I can now dump all my stuff onto it and clear a lot of phone memory....happy days.Update,,,,I have run some comparison tests for a few micro sd cards, 2 of which i have posted performance figures for external and internal formatting.All tests done using A1 SD Benchmark on Long Test on a motorola G4+ (Int Ram speed Read 192.17MB/s Write 78.54MB/s)1. Sandisk micro SD 2GB Sandisk 2 GB microSD 2GB MicroSD Class 2 memory card - memory cards (MicroSD, Black, Class 2) Read 10.87MB/s Write 7.12MB/s2. Lexar Micro SD HC (high speed) 32GB Lexar 32GB Class 10 MicroSDHC Flash Memory Card with SD Card Adapter Read 20.05MB/s Write 12.03MB/s3. Sandisk Micro SD Ultra XC U1 128GB SanDisk Ultra 128 GB MicroSDXC UHS-I Memory Card with SD Adapter - Frustration Free Packaging Read 58.85MB/s Write 10.28MB/s External format. Read 178.53MB/s Write 77.37MB/s Internal format4. Sandisk Micro SD Extreme U3 V30 32GB SanDisk Extreme 32 GB microSDHC Memory Card + SD Adapter up to 90 MB/s, Class 10, U3, V30, FFP Read 63.68MB/s Write 51.04MB/s External format. Read 178.23MB/s Write 78.64MB/s Internal format.Conclusion.If you need portability (swap the card to another device) then you have to go for External formatting, although the Read Speeds of the Sandisk Ultra and the Sandisk Extreme are very close, the Write Speeds tell a different story. The Ultra is going to slow your Recording time for anything intensive quite dramatically. If you need fast Write Speed then go with the Extreme.If you are only going to use the card in your phone (no portability) then the Sandisk Ultra is every bit as good as the Sandisk Exreme.Decide what you are going to use your card for and purchase accordingly.......I hope this helps some of you make up your minds (it has given me pause for thought).Now i have to reload the Data back on to my Sandisk Exteme card, never mind it was worth the effort.

SanDisk Extreme 32GB - Works wonderfully as Adoptable Storage on Android Mashmallow on Motorola E 3. Device shows full capacity as internal storage and it appears to operate just as fast and smoothly as native storage. Home screen animations, app loading and camera use all seem to be at good speed. I have another Android device using the Extreme PLUS as adoptable (far more expensive), and I cannot tell the difference in operation - so my advice is not to pay extra for the Plus and go for this vanilla Extreme. Remember folks, adoptable storage is all about RANDOM reads & writes (apps use lots of little files, not one big file like a video), so pay no attention to the sequential speeds; search online for micro SD random speed tests. Came in SanDisk and Amazon branded cardboard packaging, not retail packaging, but appears genuine so who cares - just make sure you buy from Amazon themselves and not from a 3rd-party seller.

I've used Sandisk micro SD cards regularly, but find myself purchasing another one yet again this happens either because I need one with a larger capacity, or, as is the case now, I have another device that requires a micro SD card. In this instance, I need a new card as I have acquired a Samsung s7.Once you open the packaging, you find a sealed plastic unit box, with the micro SD card and the Adapter.Why I appreciate buying Sandisk:- It comes formatted in exFAT, so it's plug and play- Comes with an SD card Adapter- Constructed to withstand 'shocks', a particularly useful attribute considering its for an action camera- Long and fuss free warrantyI will also add that:- I have yet to suffer any issues with a Sandisk card- Sandisk's core business is memory and memory cards- Great value for moneyFirst, I will check to determine whether my SD card is indeed genuine. To do this :- Look to ensure that the SD card has both a serial number and the identity of the country of manufacture (in this case, it's on the back of the micro SD cardNext to check the capacity :- Use a program called "H2testw" (it is free) which confirms that real capacity of the SD card (fake SD cards will have a lower capacity, but overwritten so as to display a significantly higher capacity).Finally to check the read / write speed of the card- Use "Crystal Disk Mark"Following above results, I can confirm that mine is a genuine Sandisk micro SD card and is successfully being used in the s7, and in expectation of many years of service 👍👍👍.

Works as intended, no issues whatsoever. I have one for my a New Nintendo 3DS and another for my Nintendo switch. The review would be 5* however just make sure you need the benefits offered by the extreme, and that you won't need more storage space for the SD card. I just bought another 128GB MicroSD card for my Nintendo switch because I was running out of space on this one and after doing some research, it doesn't seem like the extreme benefits are necessary unless you require fast read and write speeds from your micro SD, the ultra line should do you fine in any other case.

I spent some time understanding what the different speed ratings mean. My smartphone would not benefit from the very highest speed rating available on the market. Therefore this card was an optimal purchase for the price.This card has been no trouble. I am not using 4k video or anything like that, but I am constantly using mp3 files, photographs and so on. This card has worked like a dream. It also boosted my storage by about 500% (Samsung S7), and it was a small price to pay for the privilege. (Still would have liked a 250Gb or 256Gb card but too pricey at time of purchase. Now this new card is full up nearly, I do regret not maxing out on the bigger card, though!

Reasonably priced, effective, great storage.

good value, no issues. fast speeds and perfect playback

Got 2 of these for 2 Akaso EK7000 action cameras (go pro replica), and so far have had no problems using them at all. The cameras recognize the cards, and record in full quality to them with no stuttering. I got the camera setups mainly for handsfree vlogging and live streaming, so have not tried taking normal pictures with the cards, but I know they hold up for video recording, so I assume they hold up for any type of pictures as well.Pros/Cons:+ Small+ Fast+ Decent capacity for value (as of the writing of this post)

Esperé meses para realizar una evaluación un poco "completa" sobre la memoria en un celular (samsung galaxy s7) y espero les sirvan mis conclusiones:Al ser un tanto viejo el modelo (vaya, modelos actualizados ya incluyen la opción de apps para celular, etc.) está muy bien a la hora de trabajar. La capacidad es bastante decente, ya que puede guardar miles de archivos que necesites o cualquier configuración. En opciones por defecto del celular viene "instalar apps sobre la memoria externa" cosa que eh usado, y al no indicar que es compatible para instalar apps, ha ido de maravilla en la instalación con la opción de transferencia de datos del mismo teléfono, liberando así bastante espacio en el telefono,y siendo que la velocidad de transferencia de datos es de calidad alta, no se ha experimentado ningún problema al usar una app sobre la memoria o en la lectura de archivos sobre apps (por ejemplo imágenes o incluso, como ya mencioné, correr totalmente una app desde la memoria externa); Para probar mejor esta función, procedí a hacer el método de particionar la memoria y usar una parte como memoria interna y la otra como externa, siendo que todo elt tiempo sirvió de igual manera eficiente. No ha demostrado algún error de comenzar a leer o escribir archivos más lento o no ser detectada siendo que llega a altas temperaturas el teléfono o incluso sumergirse en agua sin dañarse la memoria. En general, es una buena memoria para el precio que tiene.Al envío fue en el tiempo indicado (ya que fue importación) .El tiempo aproximado de uso de la memoria es de medio año.

Working like charm.. Got in discount.. value for money product
