Counterfeit Card Info
❖SD AND MICRO SD CARD HISTORY❖
SD CARD - In 1999, SanDisk, Matsushita, and Toshiba agreed to develop and market the Secure Digital (SD) Memory Card. The card was derived from the MultiMediaCard (MMC) and provided digital rights management based on the Secure Digital Music Initiative (SDMI) standard and a high memory density for the time.
Micro SD card - The microSD format was made by the company SanDisk. It was first called T-Flash, and then TransFlash, before being named microSD when it started to be used by the SD Card Association (SDA).
SAMSUNG SD CARDS -
Samsung cards are great. I use them in my Samsung S7 and my wife's Samsung S5. Personally I've had no issues with them.
There are issues with FAKE SAMSUNG SD CARDS.
BAD NUTSHELL - Unscrupulous Chinese and Indian seller have been known to sell on AlumiGogo. These people will buy large qualities of smaller micro SD cards usually less than 1 GB and up to 8 GB's and they dress them up to appear to be a larger card but more importantly they hack into the card and access the part of the card that reports the size to the user. And tells it that it is a MUCH bigger card than it is. And it thinks it's a larger card. It reads as a larger card as well. And your computer or your phone or camera thinks it's the larger card - but in reality it's a 1 GB card or similar.
And sadly what will end up happening is that you will lose data, probably precious and important data because one of two things will happen 1) either the data will constantly overwrite itself, losing the older info and really never knowing until you try to access the older content or 2) it will just start giving you failed and error messages that you're at your cards max capacity.
The cards particularly counterfeited are the 64, 128 and the new 246 GB cards.
WORSE NUTSHELL - Even worse companies are popping out pieces of plastic and robbing people of their money. These are usually not being sold on AlumiGogo. They're sold in places where the seller won't have repeat business and won't ever see the customer again. Pop up camera stores, eBay, websites that aren't AlumiGogo and other auction sites.
Samsung's EVO line of cards are one of the favorite brands for scammers to copy. Now that this world record holding 256GB Samsung card is available it's an absolute sure bet that fraudsters will be trying to dupe people with bad copies of it very soon. However there are ways to protect yourself and to make sure you get a legitimate Samsung card.
From Samsung :
❖ For the last several years Samsung has made it's micro SD cards with white plastic. That means the actual card itself behind the colorful label on front is white. You can seethe white plastic on the sides. Fake cards are almost always all black, because they are generically produced low cost cards that are given a fancy Samsung looking label on the front. If the card you get it black plastic on the sides, it's not a Samsung. White plastic is more expensive to make, and fraudsters are all about doing it cheap.
❖ Buy only from reputable stabled vendors. AlumiGogo is reliable.And if there is a problem, they will take it back without hassle. There are dozens of other 3rd party vendors who are just as trustworthy. But make sure you are buying from one of those. Read their seller feedback. If there are numerous complaints from people who bought fake capacity cards or even cards that didn't work properly, find a different seller.
❖ Make sure the listing looks right. This one is fine. It's a legitimate Samsung card. But scammers will post nearly identical looking listings on AlumiGogo that have cards that look nearly identical buy don't have the Samsung logo at the top. (Recently another scammer replaced Samsung with Sanshen on fake cards. Other than that they were identical. They used the same font any everything, including the A in Samsung that doesn't have the bar in the middle). Samsung has gone with the two tone green fade on their newest cards to make it a little more difficult.
❖ Be careful of the price. If the price of the card you are looking at is significantly below the price of other listings for similar capacity cards, something is wrong. One of the biggest tricks scammers play is to make the price WAY lower than it should be in hopes of getting you to spend more time looking at the price tag than looking at the other things that don't add up right on the listing. Unusually low priced flash storage almost never works out well.
❖ Test the card once you buy it! Regardless of who you buy your Micro SD card from or what brand it is, test it out. A thoroughly way to test it is with a utility app for Windows called "h2testw". You can download it free. Just do a search for it on any search engine and you'll find it. (For Mac and Linux users there is a similar utility called F3) That app writes single bit data to the drive in 1GB file increments until it's full, then it reads that data back to make sure it's readable. It will tell you what the actual capacity of this disk is. It is not fast. It will take anywhere from 1 to 2 hours to test a 256GB card depending on the speed of your USB port. This is smart to do even if you have no doubts that you have an authentic Samsung (or any brand name) product. Sometimes things go wrong in manufacturing and quality control and a dud gets through. An app like h2testw will verify that your legitimate brand name card is working properly. And if it's not, you'll know right away while you are still in your 30 day exchange window.

Be careful! Died after a couple of months
Received this in June worked fine until yesterday. I was having problems with my mobile device shutting down and not starting up. Mobile device works as soon as I remove this Micros SD card. Putting the card in my computer I can see the files but the card is write protected. I verified that my adapter is not write protected and have tried multiple adapters that work fine with other cards. Still write protected. Many support sites state that this is a sign that the card is failing and to get my data off of it asap. I have but cannot format or erase data so my only option is to destroy card to keep data safe so that means I cannot return. Only had it couple of months. I am hoping to either hear from AlumiGogo or Samsung but I can't wait so I put in another Micro SD and the Mobile Device works great....just missing my data. If I hear back from AlumiGogo or Samsung I will come back and update my review.
I have many systems with many different micros SDs but this is the only one that has ever failed.
update 1: AlumiGogo made it right. I would give amazon 5 stars. I still have not heard from Samsung.

Genuine, trusted brand
Worked as expected. No issues with formatting multiple times to clear prior video files during the past week. Checked that it had the capacity stated (less usual overheads) during the formatting process (another reviewer had shared that looking sideways at the card would reveal if it was counterfeit - genuine Samsung cards had a white edge, counterfeits had a black edge). The actual card free space capacity was somewhere in the 59GB. I wanted the peace of mind with the brand, and was willing to pay a bit more than the cheapest card on the market.

A great SD card the packaging may be a challenge.
Came with an adapter to put in a standard SD Card slot, since this only shows the microSD card the adapter allows you to put this in the normal sized slot on laptops/computers/readers. It reads at around 80MB/s and I wrote to it max at 25MB/s. It works great on tablets with a microSD card slot I assume this will work fine on my Kindle Fire 2015. This is cheaper than the Sans Disc that is certified on Kindle Fire you do not have to buy that to use this. There is no problem so far on my old tablet. I will update if this works on my replacement Kindle Fire 7 5th Generation gets here and let you readers know. Only problem I had with it was opening it. you may need to cut it down the middle of the package to open it.

I bought this for my Samsung Galaxy Edge 7 and so far it seems to work great. It performs quickly and alleviates a lot of the storage space on my phone. It also holds up well to swapping out cards. I was able to quickly transfer my files, photos, and videos off of my phone easily after putting it in. Great buy for a good price and storage.

I don't hate the product; it worked well, but it lasted less than a year, and I was only using it for my android phone. That's a far cry from the 10 guaranteed ten years.
The warranty said it was good for ten years. I tried to go to Samsung and claim the warranty, but I can't find the appropriate information on the packaging on the sd card. (I cut off the top to get into the package; I don't have that anymore, and I don't have the adapter with me, if it would be on that.)
It went downhill when it said it did not have any information on it on day. Everything came back for a little while, and I was able to grace my photos off of it, but then I lost everything on it again. My phone won't recognize it any longer, either.
I bought a 32GB for a different company for the time being.

If it wasn't dead, 5 stars, only lasted 3 months.
I bought this card in January of this year (13 weeks ago). It worked great until yesterday. I woke up to notifications that the SD card had been unexpectedly ejected. It ejects itself every 10 seconds unless you remove the card from the phone. I tried a different SD card and do not get this issue at all. I tried formatting the card in my PC, which says it is write protected. I researched on forums and tried to follow their procedures. I can not format the card while it is in the phone, when I try it just ejects itself over and over. The read and write speeds are fast and the card worked great until it died. Would be 5 stars if the card could be reformatted/still work in my phone.

Fits Motorola E!!!
I have a Motorola E TracFone and had very little memory left. I was thinking of purchasing a new phone ( not very tech savvy ) but really like the one I have so decided to give this a shot. So happy I did! I now have 3% memory use instead of 91%!!

Failed after just over a year in a smartphone
Been using this in my galaxy S5 for just over a year now. It has worked great until now, but it has suddenly become so unusably slow that it is completely useless. It also shows up as "write protected" when I try to format it using "sd formatter". Trying a full format operation now using the windows disk management utility, but that has been underway for nearly 18 hours and is only at 7% complete. If you need a reliable SD card, I suggest you look elsewhere.

Fantastic. Highly Recommend
Highly recommend this SD card for your storage needs. I have one in my Samsung Galaxy S5 Android phone and already have about 3Gigs worth of data on it. No problems in storing the files or compatibility with the Galaxy S5. This SD card will work on all Galaxy Android phones by Samsung, as long as the specs for the phone itself allow it so be sure to check your owners manual for verification. Definitely a must have for plenty of expandable storage.
