    I love the product been working perfectly since the day I bought it. I bought this specifically for my Nintendo Switch. I previously had the 512GB Micro SD Card but quickly ran that up, so finally this card went on a discount and I was able to buy it!!!Am glad I did I finally have ALL my games on my system, no more having to delete a few here and there to make room for the next game, finally I can just sit back and Buy/Download just about anything I can get, worry free of weather or not I have enough space!!!!After the format I believe I was left with around 953GB and as of now am left with 75.8GB TOTAL left (Including System Memory), which is still very good at least to me since most games are 2 to 8 sometimes 12GB depending on the game.Anyway I have a total of 176 Games the range from huge AAA games to small Nindies (Nintendo Indies) games as well, and again am very happy with my purchase. Also you can see my current inventory of games in the pictures for better idea of what games

    The Nintendo Switch is incapable of utilizing this SD card to its full capacity. It only supports U1 speeds, and the recent Digital Foundry investigation into the Switch’s loading speeds revealed that using this card instead of a U1 rated one would actually hinder loading speeds, at least while playing Zelda. I say this to tell users that this card is overkill if that’s what you’re buying it for, and you’re better off going for a slower one that the Switch was actually designed to use.This is not the fault of anyone, just wanted to help people become more aware of it.Besides that, the packaging was really nice and well done. The card achieves its rated speeds after testing it using my computer. If you are looking at this for an expensive camera capable of utilizing it properly, look no further.

    I purchased 4 of these to use in my GoPro Fusion and GoPro7 cameras, and I couldn’t be happier. Not to mention that the price was right!!

    Do NOT solely judge this card off the speed tests (CrystalDiskMark) for example.The reason being is that it also depends on your card READER!! Yes, you could have a legit card, which i do, but can get 30 MB/s read / write speed, or even 80-90 MB/s. That’s exactly what happened to me when i tested mine to see if it was legit.Testing the speed to see if it is legit is certainly something you should do, but be AWARE that you need to have a card reader that can ALSO reach those speeds. When I first put this in a crappy USB SD card dongle that I had sitting on my desk, I only reached 30 MB/s for both read / write. When I put it in my laptop (which has a nice built in card reader) it only reached 80-90MB/s. It wasn’t until i used the SanDisk USB mate drive that can be packaged with this card (or bought separately) that I achieved the 169/105 speeds.Please don’t immediately assume you have been ripped off with a fake when you get the lower speeds.

    This review is specifically for the item SanDisk Extreme 128GB microSD UHS-I Card with Adapter – 160MB/s with SanDisk MobileMate USB 3.0 microSD Card Reader. My card was shipped from and sold by Amazon.com. The top review for this card would have you believe the product I received, based on physical appearance, is fake. The speed tests and H2testw program appear to indicate it achieves the advertised speeds and has the correct capacity using the bundled USB 3.0 card reader in a USB 3.0 port on my desktop Windows 10 PC.If this card is somehow “fake” it is quite impressive. I’m sure there are some fakes out there, but if you do decide to buy this card it might be worth performing your own tests before deeming it fake based off the looks alone (assuming it’s not an incredibly obvious fake).April 18, 2020 (13 month update): card still works great. No complaints, I’m very happy with it.

    Replaced a 64GB memory in my Galaxy S9+, of the same brand just not extreme.Now my phone has more storage space than my two best laptops… of course you know, I will buy more.This, so far, is the holy grail for portable storage… this has more memory than the SSD in my ThinkPad W530 workstation… blows my mind. As far as quality goes, you can’t beat SanDisk, they been around since the beginning in the SD card arena.This little tiny thing, is so tiny, I could put it up my rear end, after filling it with days worth of videos and unending images… doubt I will never need this much room but… I like to record a lot. This thing pretty much turned my lowly cell phone into an absolute powerhouse.

    I ordered the 1TB memory card using my fiance’s account so that I could have a lot of memory for my Nintendo Switch and it did not disappoint!!!For the people who are saying that this card is fake because the read or write speed is below what is listed, or because when you insert it into your device the available memory listed on your device is lower by about 20 GB, you just don’t understand how memory cards work. You will have less than the actual memory listed on the package available because your operating system utilizes some of that memory to work properly (don’t forget that the operating system and your system files share this memory) and your read and write speeds are dependent on what device you are using. The listed read and write speeds are just a maximum of what you COULD see depending on several different factors.I purchased my 1TB memory card last May and it’s still working beautifully and I have transferred data from one SanDisk memory card of a smaller capacity to the purchased 1TB card and even the smaller capacity one still works just fine and I purchased it years ago. There are legit ways to tell if your card is actually counterfeit or not and no it’s not by looking at the back of the card or the amount of memory on it. In fact, If you have read this and are actually still concerned that you have a counterfeit SanDisk memory card then here is what SanDisk says straight off of their website:”All genuine SanDisk memory cards should have a serial number and a manufacturing country’s identity. You can not determine the authenticity of a SanDisk card from an internet stock photo.You can not determine the actual memory capacity of a counterfeit memory card by simply viewing the capacity displayed by your computer, phone or camera.”So if you think that your card is a fraud and you reside in the United States, then you can contact SanDisk’s customer support here: https://kb.sandisk.comI hope that my review is at all helpful to at least a few people and that those who actually do end up receiving good cards but were confused by other reviews gain some clarity, and those who think that their cards are not legit can actually get support from SanDisk.

    I got this for my Nintendo Switch.Nintendo must have had a busy few days the day I got this and started redownloading my archived games and whatnot onto it because the downloads were super, super slow and frequently crashed. I was afraid it was the card malfunctioning.However, a week after finally getting all my games redownloaded and whatnot, everything is running spectacularly, even better than with the smaller capacity SD card I had in the console before.Honestly, when I first got my Switch I didn’t think I’d need a large capacity SD card… I was proven wrong in a year. So, I got this and if I ever do fill it to capacity… well I’ll be d*mned.

    Since 1TB is still fairly new on the market, it’s inevitable that this little piece of sophisticated plastic and metal would cost an arm and a leg. Fortunately, I snagged it on sale on Prime Day (usually on my birthday).Not only does it work flawlessly on the Nintendo Switch, it runs games without any noticeable slow down. I’m one to like keeping my Switch games ready on the go, so this SD card is paired up with my decked out Switch Lite, while the big papa is at home sitting pretty with it’s less formidable SD card installed (still in the triple digit GB capacity).Happy Switch, happy b*tch (me). 😀 Sorry… Couldn’t think of anything catchier. lol!

    Just got the card this morning. Speed almost matches or slightly exceeded the rated speed on matching USB reader from SanDisk: 160MB/s+ read, 95MB/s+ write. Performed very decent on built-in SD Slot: 90MB/s+ read/write). Both results from the same laptop: Macbook Pro Late 2013, 2.4GHz Intel i5, 8GB RAM, USB 3.0.I copied over 120GB of data from another card (with dd between two /dev/rdiskx). It sustained 49MBps+ for the *entire* write. The speed was probably limited by the source SD Card.I was running Windows 10 on VirtualBox using the SD as the RAW disk. Windows 10 is fast enough to be usable. (Samsung EVO Pro Endurance was way too slow to be usable, in comparison.)
