  • Legit card. Legit fast.
Style: Card Only Capacity: 128GB
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 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. ... show more

  • Either fake or defective
Style: Card Only Capacity: 128GB
First red flag was when I looked underneath the card. Instead of being solid black like every other SD card I've seen, it looked like a green circuit board with a strange black square on it. Second red flag was the MUCH lower than advertised read/write speeds (only 50-55 write with mid 80s read). Third red flag was when I tried to copy data from my old sd card on to this one. I was able to get about 21.5 GB of data on to it until it unmounted itself from my computer. I then physically removed the card and inserted it back in the computer. Windows recommended that I repair the drive, so I did. After that, I go and try to copy the data again and it unmounted itself, just like before. I tried the same thing by repairing the drive, except this time, Windows informs me that it could not be repaired! Seriously?? So much for trying to get a good black Friday deal... ... show more

  • A Miniature Storage Behemoth
Style: Card Only Capacity: 256GB
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. ... show more

  • Working fantastically for Nintendo Switch!!!
Style: Card Only Capacity: 1TB
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 ... show more

  • Advertised read speed is false!
Style: Card Only Capacity: 128GB
SanDisk advertises this as the fastest read UHS-I in the market (160mb)! Multiple tests on the 128GB don't confirm this claim. I tested the card on my Surface pro (2017), Surface GO and XPS 13 and got only 88mb read speed and 84 write speed at best!! My Samsung Evo select 128GB & 256GB have higher read and write speed. ... show more

  • Very fast, but look elsewhere if buying for a Nintendo Switch.
Style: Card Only Capacity: 128GB
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. ... show more

  • Lies about speed
Style: Card Only Capacity: 128GB
Like many of the other reviewers pointed out, this card is fraudulent. "U3" and "A2" my ass! The read/write speeds are nowhere near the advertised values. I'm getting 74/66 MB/s which is worse than my Samsung 128GB U1 microSD. Non-sequential writes are awful at 6/2 MB/s. $30 might seem like a good deal for this card but it's not. Don't be fooled! ... show more

  • Fast enough to use as extra storage on Surface Pro 6 but not as fast as expected
Style: Card Only Capacity: 128GB
The built-in SSD disk space is extremely expensive on the Surface Pro 6, so getting the smallest Surface Pro 6 and using a microSD card to complement the built-in storage is an attractive option in my opinion. The good thing is that this card performs well when inserted in the microSD card reader of the Surface Pro 6 (about 80 MB/s sequential read, 80 MB/s sequential write) although it does not reach the advertised speed (which is "up to" 160 MB/s sequential read, 90 MB/s sequential write). As I believe the UHS-1 standard is limited to 104 MB/s anyway I am not sure if it is possible to find microSD cards that would perform faster. In short a good choice for the Surface Pro 6 even if possibly not the best choice. ... show more
