abunda_amazon_reviews 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.

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).

Lies about speed
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!

Fast enough to use as extra storage on Surface Pro 6 but not as fast as expected
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.

Read/write speeds 70/50 mb/s
Read/write speeds were 70/50 mp/s on my S9. Much slower than the max of 160/90. Opted for the Extreme Plus instead, more expensive but read/write speeds are 100+/80

A Miniature Storage Behemoth
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.
