I have purchased two of these so far and in both cases, they both get corrupt after using them. I bought them specifically for my dash cam and after about a two month span, they start getting corrupt (probably from the overwriting). IDK, just thought they should perform better than that.

Best in class

Reviewed in the United States on August 6, 2018

Intended use case: Expanded storage for my phone, the Samsung Galaxy Note 8. I intend to use this for images, videos, movies, and as many apps as possible.
This product as a solution: I have used Samsung SD cards for years in GoPros, cameras, phones, etc. and I can honestly say they are the best. Fastest transfer speeds, secure, and I've only lost data from a corrupted card once or twice (in about 9 years of use). Needless to say, the card functions perfectly. Be aware that some apps will not be able to move to an SD card, but that is to optimize performance and fine. Slow-mo video must also be recorded on the native storage. 128 GB is more than enough for plenty of movies, photos, games, etc. This card will not disappoint.

SIDE NOTE: Do not skimp on SD cards. The extra money is minimal and totally worth it -- trust me.

Verified as authentic Samsung Micro SD card

Reviewed in the United States on March 17, 2018

Capacity: MB-MC128GA/EUVerified Purchase

There's a lot of fake micro SD cards being sold to unsuspecting customers online, especially the Samsung cards since they're usually one of the best available. These fake cards while they look virtually identical to the OEM cards are usually smaller in size such as a 8GB or 16GB actual size card which report themselves as being 128GB+ in size. Not only are they not the correct size of storage, but their read and write speeds are inferior to the OEM cards.

With this ongoing problem in the market, it's made it very difficult purchasing any Micro SD cards online from retailers such as Amazon and more so Ebay. Due to this problem I have collected an assortment of software tools to inspect the authenticity of every SD card I purchase. These tools include Chip Genius, FakeFlashTest, and H2testw on the PC, along with a couple Android Apps on my Samsung Galaxy S7 Edge phone.

I am happy to report, my inspections have concluded these cards being sold on Amazon are authentic Samsung cards. I even have an identical Micro SD card purchased directly from Samsung's website and all the reported data findings are identical on this card besides the serial number which is what I would hope to find.

I'm going to include some screen captures from the apps I used on my Samsung Galaxy S7 Edge phone as a reference, so you should know what to expect from an authentic Samsung Micro SD card.

Review Update:
I recently purchased a 256GB Samsung Card from another online retailer not named Amazon, where the seller had 100% positive feedback, was an established 4 year member and the price wasn't that much of a savings over what I had seen listed on Amazon for the same item. I contacted the seller to verify the authenticity prior to purchase. All signs seemed to indicate it was a Legit Samsung card, but upon arrival I learned differently that it was a fake. I got my money back for that item, but sadly another unsuspecting victim made a purchase at the same time and left the seller a positive feedback review. That's because the fake cards to work until you lose your data because you exceed the real storage limit of the card which is typically 8GB.

Now having a REAL Samsung SD Cards and a FAKE in hand, I thought I would take that opportunity to assist others the visual differences between a REAL and FAKE Samsung SD card. See added REAL vs FAKE images. The FAKE is not from Amazon.

Review Update 2/28/2019
I have observed some reviews where they have stated they received a fake. Hopefully, my original review assisted in identifying that it was indeed a fake. My thought on this is because although you are making your purchase on Amazon, the item is actually "Sold By" multiple vendors under the same Amazon listing. I have been asked by multiple individuals to specify who my Authentic Samsung cards were sold by. I've now made multiple purchases of Samsung EVO SD cards through Amazon. Below is a list of the sellers from whom I have received authentic Samsung SD cards from my purchases.

legit chip -- tested with H2testw -- but heed a warning

Reviewed in the United States on January 28, 2019

Capacity: MB-MC128GA/EUVerified Purchase

The very first thing I did upon receiving this chip was test its authenticity using the H2testw freeware -- something you should ALWAYS do with a new chip, no matter where you get it from, because there are counterfeit chips everywhere and many look remarkably authentic. I'm happy to say that this Samsung clocked in at 122 gigs with zero data errors...a little shy of the stated 128 capacity but it seems like storage always falls slightly short of the stated capacity so that's OK. Speed was an unremarkable 44.2 MByte/s writing, 68.1 MByte/s reading...but this test was conducted on an old PC through the SD adapter so no dings there. Overall, this chip is what it purports to be.

The warning is that I could not initially run the H2testw because it couldn't write to the disk, nor could I do a fast format. This initially set off alarm bells, but it turns out that what I had to do was a time consuming full format. After I did this, everything was fine. No idea why the disk wouldn't take a fast format or accept a read/write test out of the package. As an aside, the H2testw can take a long time -- it's a thorough test, but not particularly efficient. But don't be impatient. Fire up the test, go have lunch, or let it run in the background while you do something else as it takes very few system resources. When you're done, you'll be rewarded by knowing just what exactly that chip you have really is, and if it's safe to slap your precious data on it. Time well spent.

Purchased from OEMPCWorld, Real product

I purchased 2x64GB EVO+ and 1x128GB EVO+ micro SDXC cards from OEMPCWorld, and all three are real. Windows users should use H2testw and Linux should use F3 probe in addition to visual verification instead of relying solely on visual or intuition.

Several people are claiming fake just because a 128 GB (SI) registers as 119 GB (GiB), but what they're failing to understand is that hard drive and flash memory manufacturers market 1 GB (SI) as 1,000,000,000 following SI; however, 1 GB for computers is not supposed to be measure via SI but by bytes where 1 GB is 1,073,741,824 bytes; however, a lawsuit in the mid 2000s saw the courts settle that GB is SI and GiB is based on bytes. Therefore, whats marketed as 128GB (SI) will show up as 119GB (GiB) and doesn't necessarily mean its fake. To make matters worse, Operating Systems still show GB more often than GiB. Lets all thank Seagate for starting this trend...
