    Just what I needed for my GoPro11, it said they are too slow for some features when I put it in the camera but I haven’t had any problem with them so far? So I’m not sure what features this will affect, Worth the money and I would recommend

    Great product, large 1TB capacity, fast, and works first time.
    Installed this 1TB sd card into my Nintendo Switch OLED which greatly increased the 64GB internal memory.

    Also installed this 1TB sd card into my Steam Deck 512GB, which also greatly increased the 512GB memory.

    This 1TB sd card worked first time with both the Nintendo Switch and the Steam Deck consoles, it is fast and reliable, and games can be installed or moved to the sd cards of both consoles, and run from them, practically as fast as the internal memory.

    Well worth getting for both consoles.

    Works on phone
    Used on my android/motorola phone no problem at all. The phone just sorted itself out. 256 GB seems to be the upper limit of what the phone can use, so that is what I went for.

    Superb micro sd card
    Added these to the Amazon pads that I have bought for my kids, a great cheap way to expand the memory.

    Works perfectly with PSP 1000.
    This card works perfectly when paired with a Memory Stick PRO Duo Micro SD adapter for the PSP. Delighted to have the extra storage!

    Almost Perfect!
    Overall great product! My only issue I found (which might be my fault) is I use it in a dash cam which captures in 4k but this sd card doesn’t allow it to capture that and only in HD or lower. The sd card wasn’t recognised in my computer either.

    Good for Steam Deck
    USE CASE – Steam Deck
    For the Steam Deck, I got the 256GB microSD Card. I have an NVMe SSD in the steam deck and I can’t see any difference between the internal storage and the microSD card. Worth for adding more storage for larger or smaller games. Would recommend if you need extra storage.

    Random read/write speeds which matter for games is seemingly fine, no long loading times or any noticeable loading issues.
    Comes with an Adapter as a bonus for microSD.
    Minimal packaging.

    It is still expensive for just an microSD card with fairly low specs, the Max Read/Write speeds are something everyone probably won’t ever use in a real world scenario.

    As described!
    I was hesitant as the previous reviews stated that their sd cards were displayed as a lower GB than what they had bought. However upon checking, my 128GB came just as described. I recommend!

    As you can see 119GB is close enough, with space for 33977 photos (I’ve taken quite a few already). These stats were taken from my samsung DV300F and canon powershot SX170IS digital cameras.

    Couldn’t fault it!
    Works amazing on my security camera and I haven’t had any problems with it! Has enough storage to record footage for a couple days so definitely worth it!

    Probably the best price/performance balance for data cards
    These cards are ideal to use on SBC devices such as a Raspberry Pi, as they have the A1 classification.

    That means they are excellent for random-access of the data in the card, which is a requirement for proper performance in these devices.

    You get 2 of these for a very good price, so I see nothing wrong here with this deal!

    No failed photographs of 10,000 in Antarctic weather that stressed all the guages.
    Micro SD is fiddly to get in to and out of my laptop slot. A faster card would always be welcome with more than 2 Tb of backups to copy, but those cards are substantially more expensive. Reliability and a genuine card from a trusted manufacturer was vital after previous fails.

    Easy as Pie
    I’m no expert on Macs, but needed to shift some large video files off my Mac Mini, due to drive being full.
    The cost of upgrading storage memory to a Mac is ridiculous, so thought I’d try this instead. Bought a compatible USB 3 stick where you plug the micro SD into the back. Then plugged the stick into the Mini.
    No need to format. Just copied a large 4k 60fps file to the card. Out of curiosity, I tried playing it straight from the card. Ran as smooth as butter. Storage problems all solved for less than £25.
    Next time I’ll buy the 500GB one. Very happy!

    Reliable microSD for phone
    My Huawei P9 was full and I was having to delete useful apps just to keep the important ones working as they needed updating and I didn’t have the space for the update.
    This new memory card has massively expanded my phone memory, it works well with my phone and PC and is reliable so far. If I have any issues with reliability down the line and I will update my review to say so, but so far so good.

    Good but not great
    Bought the SanDisk Ultra 128GB from the “Sandisk Store”.
    150 MB/s “transfer speed” is the advertised speed. There’s no such thing as “transfer speed”: only read speed or write speed. These are about 100 MB/s read and 50 MB/s write, as shown in the CrystalDiskMark snapshot above. The back of the packet has the usual weasel words – but this was tested on 2 separate USB3 readers on different systems, with different block sizes, fully formatted and quick formatted etc etc. All with pretty much exactly the same results (within 3%).
    I’m keeping my 2 SanDisks: they’re ok for what I need. A good price for this size.
    Why did I give it a 5 star rating?
    Who reads 3 star rating reviews??

    It’s a good card
    It’s not the first one I had, I am pleased with them
