    Good Card, Accurate Speeds
    5 Stars
    Good Card, Accurate Speeds
    In short this is a great card and it's speed falls close to it's advertised speeds. ADVERTISED ACTUALREAD: 160 MB/s 149 MB/s (93.13% of advertised speed)WRITE: 90 MB/s 109 MB/s (121.11% of advertised speed)The results above are from the SanDisk Extreme 128 GB card, SDSQXA1-128G-GN6MA bought in Q1 of 2021.Unfortunately, there are MANY fake SanDisk cards on the market everywhere and they can be very problematic if bought and used. I highly suggest you test ANY sd card that you buy. In general, I always want to get at least 90% of claimed speeds. Different hardware or software optimizations can make it to where you may not get speeds as high as claimed, but if you are close to them, close is good enough.Only read on if you are researching SD cards and verification or are just a nerdy person like myself.When looking up SD cards it's important to keep a few things in mind:* Investigate the claims for speed if it is important to you. The card may say xxx MB/s write speed* That asterisk may reference that the speed is only guaranteed when using a certain software. Since you might be like me and installing the card into a phone, that phone will most likely not use that software so the speeds will be lower. For a more real-world speed, look at reviews who have verified the speeds either in the device that you plan to use it in, or by other software to benchmark it.* Always test the speed of the card once you get it (The speeds above come from a program known as H2testw)* Always test the storage capacity of the card.* I highly recommend that you test your card using H2testw. It tests the two most important things about your storage: actual speeds, and actual storage. Fake or faulty cards cannot hit their advertised speeds. Fake cards often are edited to report a false storage to your computer. Say you buy a 128GB card and you read the size in Windows, 119 GB. Seems close enough right? Well this is not a guarantee of the real storage capacity. The card could be a 4 GB card that is written to report itself as 119 GB. For the first 4 GB of space or so there will be no issues with the card, aside from likely slow speeds, since fake cards often use slower, cheaper memory. After writing these 4 gigabytes however, you will inevitably have data corruption. The original 4 GB stored on the card will start to be overwritten by the next data to come. This can result in a total loss of date. This is the big danger with fake cards. It's one thing to have a slow card, but another thing entirely to lose your data. You could lose valuable data and there are times when this data cannot be recovered.* Know that your storage space will always be less than advertised. In my case, my 128 GB card has an actual storage space of 119 GB. This is in mainly due to the fact that the advertised capacity is often the unformatted, "RAW" size in decimal (base 10) storage. However, your computer reads storage in binary (base 2) storage. In this case, if we take 128 GB of decimal gigabytes and convert it to binary gigabytes, we get 119.21 binary gigabytes. When your card is formatted, it is formatted using base 2 since your computer understands binary. Decimal is essentially only used for advertising as far as us typical consumers are concerned. H2testw will test the true capacity by filling the entire card with however much information it can put into it, then reading it back and verifying that the information stored is correct. A fake card may be 4GB and allow 119GB to be written to it, but when the information is checked, there will be discontinuities in the data and the fake card will be exposed as such.Good luck finding a card that works for you.

    5.0 out of 5 stars Test results - Amazon basic 256 vs SanDisk Extreme 256 (with earlier cell phone usage review)
    Reviewed in the United States on May 12, 2019
    I am reviewing and comparing two different memory cards, the Amazon basics 256gb and the SanDisk Extreme 256gb card.

    First is price, the Amazon basics is a several dollars less than the SanDisk (at this moment 23.72 vs 36.99). Currently Amazon says there is a newer version of the SanDisk for 24.85, however I have not purchased or tested the newer version.

    The two cards:
    "SanDisk 256GB Extreme microSDXC UHS-I Memory Card with Adapter - Up to 160MB/s, C10, U3, V30, 4K, A2, Micro SD - SDSQXA1-256G-GN6MA"
    "Amazon Basics microSDXC Memory Card with Full Size Adapter, A2, U3, Read Speed up to 100 MB/s, 256 GB"

    Tested using:
    CrystalDiskMark 5.5.0 x64.
    Computer is a 4-year-old "NUC8i7HVK" running Windows 10, and it has a built in SD card reader (Intel calls it "SDXC with UHS-I support"). This interface is what I call "SD reader" in the accompanying screen captures.
    I also tested using a SanDisk USB 3 adapter "SanDisk MobileMate USB 3.0 microSD Card Reader- SDDR-B531-GN6NN". This interface is what I call USB3 in the accompanying screen captures.

    First, I noticed a UK review where the reviewer noted the Amazon basics card seems to be missing 5 gigabytes of storage even when the (confusing) translation from computer storage gigabytes (1024 x 1024 x 1024 = 1,073,741,824 bytes vs 1000 x 1000 x 1000 = 1,000,000,000 bytes) vs "we sell storage" gigabytes.
    You will notice CrystalDiskMark reports the Amazon basic card as 233GiB versus the 238GiB of the SanDisk, so he is very correct. I have no clue why the discrepancy, but it is slightly smaller than it should be.

    Second, to get the real read/write speed of the SanDisk card, you will notice I had to use the SanDisk USB 3 adapter. Using the built in SD card reader, both cards were very close to identical results.
    Using the SanDisk USB 3 adapter, I did manage to exceed the ratings for the SanDisk card (up to 160 MB/s read, and up to 90 MB/s write) giving 169 read and 105 write. The Amazon basic card did have a slight change using the SanDisk adapter, but really not significant.

    Both cards were close enough to their claimed specs to not worry about it, however it should be noted that you need the SanDisk adapter to actually get the much higher speeds of the SanDisk.
    I will be using the Amazon basic card to store children's movies for my granddaughter to play on her new Kindle, it is plenty fast enough reading to do full HD movies.

    Note that both cards were brand new when tested and had never had anything written or read from them prior to the test. The Amazon basic seems a good value and is certainly adequate for normal use in a cell phone or laptop. The SanDisk would really shine if you used the adapter to move lots of larger files to it.

    Older review:
    I've now purchased this card 3 times from Amazon (as seller) and I'm very satisfied. Used in Moto g7 and Moto g7 power phones with excellent results!
    Mine was sold by Amazon, and certainly is a fast card. Installed in a Moto G7, tested at 89 read, 59 write using A1 SD benchmark for android. Maybe not the rated speed, but Motorola phones have a history of bad SD compatibility. Tested others, and this card is significantly faster. Very happy with the product.
    Note that I've attached some results testing on a PC with a Lexmark reader, thus it doesn't attain its full speed.

    Entrei em contato com a SanDisk. Tirei foto do produto via chat e mandei para eles confirmarem se era original. Confirmaram, produto é original mesmo. Perfeito.

    A taxa de leitura de escrita está de acordo com os valores mínimos de um cartão v30. Pelo meus testes ele até ficou oscilando entre 10 a 20mb a mais dos valores padrões. O que é mostrado na embalagem é uma performance teoria de leitura e escrita e não o valor factual do mesmo.

    Transferi mais de 40GB ao cartão, ele fez bem o serviço, mas nós 3 últimos arquivos recebi erros de input/output(leitura e escrita para quem não sabe). Parei o processo e iniciei ele de novo e foi gravado tudo direitinho. Acredito que tenha sido até um problema em relação ao fato que eu tentei acessar o cartão utilizando outro app enquanto fazia o processo de gravação. Está tudo rodando ok e bem rápido. Se você estiver usando um cabo USB 2.0 ou uma saída 2.0, até outros dispositivos que tem uma taxa de transferência de dados pequena por natureza, não espere que fique rápido. Não seria um problema com o microsd. Enfim, recomendo. Muito bom. Estou usando como memória interna de um celular.
