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. 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...;;Reviewed in the United States on November 29, 2018;;1.0 out of 5 stars;;Either fake or defective;;Larry Lopez;;/gp/customer-reviews/R1QZ1LYV08W9SG/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B07FCMBLV6;;;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.;;Reviewed in the United States on October 14, 2018;;2.0 out of 5 stars;;Advertised read speed is false!;;Amazon Customer;;/gp/customer-reviews/R34QU37AA9HZBG/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B07FCMBLV6;;;I have several mini memory cards from last year and none were fast enough for the new Dji Mavic Pro 2 or the ZOoom. There was even a warning that popped up on the GO 4 app that will say SLOW where the sd card info is. After installing the Sandisk Extreme U3 A2, the SLOW warning disappeared and all is well. Havent been able to use as the weather here in the great Pacific NW has been rainy but once the sun comes back I am flying! ***Update October 21st, 2018*** I ended up installing the microsd in my new Moto Z2 Force Smartphone right after the review, since the weather for flying the drone won't be nice again till next year. It worked awesome in the Moto for over a week until it died and said it became corrupted. I had many photos and videos that were transferred and lost. Called and emailed support and was asked to jump through hoops so am not very happy about the card and experience with it. Will be buying a different brand and hoping for a better ending.;;Reviewed in the United States on October 2, 2018;;1.0 out of 5 stars;;SanDisk 64GB (3) A2 Corrupted itself after week of light use!;;DagDerNiT;;/gp/customer-reviews/R21PZ6J2TMO60J/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B07FCMBLV6;;;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).;;Reviewed in the United States on March 2, 2019;;5.0 out of 5 stars;;Legit card. Legit fast.;;Mike;;/gp/customer-reviews/R95A9QHG80H47/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B07FCMBLV6;;;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!;;Reviewed in the United States on December 11, 2018;;1.0 out of 5 stars;;Lies about speed;;E. L.;;/gp/customer-reviews/RZ2642IM0GSNA/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B07FCMBLV6;;;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.;;Reviewed in the United States on November 30, 2018;;3.0 out of 5 stars;;Fast enough to use as extra storage on Surface Pro 6 but not as fast as expected;;Gabriel;;/gp/customer-reviews/RNJCQ2YAID3AB/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B07FCMBLV6;;;Read/write speeds were 70/50 mp/s on my S9.

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.;;Reviewed in the United States on September 30, 2018;;5.0 out of 5 stars;;A Miniature Storage Behemoth;;Amazon Customer;;/gp/customer-reviews/RNR3HXV2F6FUK/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B07FCMBLV6
