Samsung 128GB EVO Plus Class 10 Micro SDXC with Adapter (MB-MC128GA/EU) Read:up to 100MB/s

I got a duplicate item, it's not original Samsung Evo memory card. It's cheap quality and I didn't even get the adaptor with it. It was totally a cheap move from Amazon. I never expect something like this from Amazon. And the pack of memory card was already opened. Look like somebody opened and used it. The appearance quality of memory card is too cheap. I didn't even get the mind to check it's transfer speed and to use it. Iam returning this order asap.

Dislike

Samsung 128GB EVO Plus Class 10 Micro SDXC with Adapter (MB-MC128GA/EU) Read:up to 100MB......item very much satisfactory and amazon delivery agent were very prompt,thanking you for the same......

Cartão de execelente qualidade, superou minhas expectativas. Comprei este cartão sd para ter ainda mais campo no meu celular S10, optei pela Samsung pois imaginei ter uma "sincronia" melhor, dado o fato de ser a mesma fabricante do celular. E meus palpites estavam corretos! O cartão desempenha com uma velocidade de gravação e leitura tão alta que é imperceptível notar quando um app está rodando na raiz ou no SD. Sou um usuário hardcore do celular para jogos pesados, e jogatina de longas horas enquanto escuto música (baixadas no sd) pelo spotify. Recomendo para usuários em geral, mas vejo como escolha obrigatória para quem possui celular Samsung.

Een perfect product voor zijn doel!

128GB U3: i've been burned before but this was a genuine samsung sd card (from kingdisk store): had the encircled v at the back of the card and samsung's sd card authenticity check software said it was genuine. the speeds are also great: single file transfer: ~80MB/s write and ~100MB/s read (average) using a usb 3.0 transcend sd card reader on windows.

The very first thing I did upon receiving this chip was test its authenticity using the H2testw freeware -- something you should ALWAYS do with a new chip, no matter where you get it from, because there are counterfeit chips everywhere and many look remarkably authentic. I'm happy to say that this Samsung clocked in at 122 gigs with zero data errors...a little shy of the stated 128 capacity but it seems like storage always falls slightly short of the stated capacity so that's OK. Speed was an unremarkable 44.2 MByte/s writing, 68.1 MByte/s reading...but this test was conducted on an old PC through the SD adapter so no dings there. Overall, this chip is what it purports to be. The warning is that I could not initially run the H2testw because it couldn't write to the disk, nor could I do a fast format. This initially set off alarm bells, but it turns out that what I had to do was a time consuming full format. After I did this, everything was fine. No idea why the disk wouldn't take a fast format or accept a read/write test out of the package. As an aside, the H2testw can take a long time -- it's a thorough test, but not particularly efficient. But don't be impatient. Fire up the test, go have lunch, or let it run in the background while you do something else as it takes very few system resources. When you're done, you'll be rewarded by knowing just what exactly that chip you have really is, and if it's safe to slap your precious data on it. Time well spent.

Purchased for my Samsung Galaxy S7 Edge to add more capacity. Usually use Sandisk cards, but given the phone was from Samsung figured it was worth sticking with the OEM this time around. Performance is as good or better than the phone's controller is and can handle 4K video recording without issue (about the most demanding thing it's capable of). Full sized SD sled is included in the package and is more sturdy than most other cards are provided with. Shipped in full colour retail packaging (blister pack) that is well protected from shipping damage.
