Sandisk’s 128GB Ultra MicroSD Card Review.

Whether you need it for a phone, a camera, or some other gadget, buying a microSD card seems like a pretty simple thing to do, right?

Well, at least, not in Nigeria, and this is as a result of the influx of fake products in the country.

Now, Sandisk is one of the first companies to introduce microSD cards with the A1 rating:

…And these Class 10 UHS 1 microSD cards are some of the best options if you are looking for fast performance on a budget.

I got the 128GB SDXC (Secure Digital eXtended Capacity) variant from Sandisk and the package looks similar to what we saw on My Passport portable drive which had all the information you need right there on the package.

However, one of the telltale signs of buying an original Sandisk card is with the internal package, this one:

Most Sandisk cards come with cellophane cover over the back, which can be quite difficult to remove:

Away from that, you also get a standard SD adapter:

As far as performance is concerned I placed it in my Nokia 7 Plus:

And used the A1 benchmark app to test the performance. At the end of the test, I was able to get a read score of 79.46MB/s and a sequential write score of 50.77MB/s.

Meanwhile, in my CrystalDiskMark testing it managed a sequential read speed of 89MB/s – just a little shy of the 100MB/s SanDisk claims – though write speeds were a more modest 27MB/s.

What this means is that Sandisk’s Ultra cards are perfect for recording full HD video but falls a little short of what you’d require for quality 4K video recording.

So, over to you, what do you think? And what memory card are you currently using?

    Wow 128GB mcard, I don’t use any memory card at all….32gb internal storage is enough for me on phone.

      On one hand:


      Cos of my Samsung Note 9.
      On the other hand:

      Cos Tecno Camon 11 Pro.

  2. This looks good
    And it’s an added advantage just that very soon importers will fill the market with a pirates version of it

    Am currently using a 32gb advance mcard 1year and 6 months old 😂 😂 😂

  3. 128 GB is cool but I’m not using it in my phone… I don’t think i need it… 64GB is fine for me… I don’t keep unnecessary file on my phone and I hardly take photos. I stream music and movies online so there’s no point having a 128GB SD card… I only need a 64GB to save games data and nothing else… I don’t really find a need for an SD card if not for games😋

    I use Toshiba for my phone, all though its only 8GB and I’ve been using it for about 5 years now. I have it in mind of buying the 128GB like this particular one.

  5. Abdulsamad Umar says:

    128Gb in a mobile device is an Overkill for me… I’d rather use it as an external storage system for my PC

  6. Alexius Ide says:

    I think the write speed of the card is pretty ok I like it cuz memory cards are seriously useful especially with phones
    Well im currently using a SanDisk actually but 64Gb

    HEY MISS TECHY
    THESE GIFs ARE AWESOME, love to watch it replay.😊
    ON MY LAST POST ON THE 2TB SANDISK DIGITAL PORTABLE DRIVE, I MADE MENTION THAT ONE OF THE MAIN REASON I LOVE SANDISK WAS BECAUSE OF THE SPEED IT IS INCOMPARABLE.
    -I CAN’T RISK BUYING ANY OTHER SD CARD THAN SANDISK, 100mbps (😵 this is hypnotic) I’VE NEVER SEEN SUCH BEFORE. I I BOUGHT A 64GB SANDISK WITH JUST 8.MB SPEED AND IT IS FAST VIDEOING AT 1080p.
    SO UPGRADING TO THIS WILL BE MIND BLOWING, BECAUSE THINGS WILL WORK BEFORE THE SNAP OF A FINGER.

    FOR ME, I REP 64gb SANDISK, IF IT IS NOT SANDISK IT CAN’T BE SANDISK.

    AUNTY TOBI, DON’T WANT TO TELL US THE PRICE AGAIN RIGHT!😂😂
    ANYWAY THAT’S BY THE WAY, THANKS FOR THE INFO NICE WRITE-UP.

    I use a SanDisk 32gb sd card cause that’s the highest my phone supported. I bought it from Aliexpress last year. It has been working well.

    Had this 😍ly Toshiba m.Card (64GB) that I attempted to use with my ex transsion. Piece of shit succeeded in corrupting the card 😔. Like, how do you:
    ▪insert an awesome Toshiba m.Card inside your transsion phone
    ▪ the phone recognises the m.Card
    ▪the phone asks you to format the m.Card as external storage (there’s no option to format as internal storage, sadly)
    ▪you carry out this format process
    ▪phone is used for a period of time with no particular storage issues
    ▪you connect ur phone to a laptop/pc in an attempt to transfer some really important por.. documents
    ▪And then, voila (Which is actually French for “And then I suddenly realised”)
    ▪the m.Card is shown to be 95% filled up. Like, what the f $&%?? I HAVEN’T EVEN USED IT!
    ▪ok, then u disconnect the phone yeah,
    ▪you try to investigate the whole shebang
    ▪And then, voila (Which is actually French for “And then I suddenly realised”)
    ▪transsion error message: SD Card is damaged.
    ▪these steps repeated themselves over and over again to where I almost reached my breaking point.

    NOTE: The m.Card was original. Ultimately I had to give it away cus the pile of the faeces that was my transsion phone forced me to believe that the m.Card was bad/kwarrupted 😔. HR manager I gave it to had no complaints about the m.Card whatsoever. She even wanted to pay me for it but I refused thinking I was selling her fake shit. The irony. Though now I use a San Disk 32GB (no idea if it’s original or not & I don’t care) and it works just fine 😔.

    I hate u Transsion Holdings Global (or whatever ur name is), I really hate u.

    1. Sounds strange though

      I have been using an Advance m-card on a Transsion device for 1 year and 6 months
      And not for once did I have any issues with it (still using it until now)

        “Sounds strange though”
        I know right? And that’s just you hearing about it. Now imagine me living through the ordeal. 😔😔

  10. Blizz says:

    Please where can I get the authentic one and how much does it cost?

  11. Abok Istifanus Madaki says:

    I bought 128gig SD card on jumia last year and after using it for two weeks, it crashed. I wasted good money on that stuff for nothing but i have learnt not to trust jumia for quality products.
