Believe the "Fake Card" Hype - Photo to Prove It
September 30, 2018
Top card doesn't work / Bottom card works. Bought the top card June 18 2018 for a Nintendo Switch and the games would download to 99% and then suddenly I'd get an error. When these cards went on sale recently I bought a new one just to see if it was the card. I could not BELIEVE how different the fonts were! Check out photo. Also the color of the bad card is off (slightly more purple and less red). Sure enough, I was able to download games to the new card without incident. The real product works great but I just can't justify giving 5 stars when I had this experience. Buyer beware!

Defective card
August 13, 2018
After trying and trying repeatedly to use this microcard as a replacement in my Samsung S7 - hours of frustration, seeking guidance from internet, friends, etc. I gave up, thinking it was just my ineptitude. Tried again several times, it would never work.
Finally, decided to try a different/new card. Sure enough...worked right away! So, by now the 128 GB card ordered May 2, is well past its "return by" date, when I determine it is defective. Now what do I do? Searched on Amazon, but found no instructions for this situation.
Giving it 1 star in hopes this can be rectified. I use SanDisk cards all the time and have never had a problem like this before.
Just found out from SanDisk that this card is a fake - not their product. Guess I am screwed unless Amazon steps up and makes it
good. Need to somehow punish this seller "Lecu Computer" for giving Amazon a bad name and customers a bad product!

Excellent card! My 32 gigs of space on my Switch got used up, so I’m on to this 64gig card now. The Ultra is the fastest that the Switch can use. Don’t bother with the Extreme.
December 5, 2018
Was a real SanDisk Ultra 64G type 10 and meets the speed ratings.
It came preformatted with exFAT and is correct 64G chip, not a fake.
Please note that Amazon is throwing all the reviews for all the chips into one place. So if you want accurate reviews, be sure you are looking only at reviews for you particular chip. This review is only for the SanDisk Ultra 64G microSD with SD adapter.
I ran a free drive and memory test program on it. It passed 5 complete passes of testing every memory byte in several different test patterns without any failures. This verified capacity and accuracy of read writes over a few hours time.
I then ran ATTOs Disk Benchmark tool and it's results show that it does reach very near 100MB/s read speeds and 40Mb/s write speeds. No laptop I have or other device is as fast as my computer's USB 3.1 ports so that seemed to be the best way to test. See the screen capture of the test results attached. Like most SDs or microSDs they do best when working with 64kB or larger transfer sizes. I've found this to be common for 16G SDs all the way up to 400G SDs. That might be a function of the USB port rather than the actual memory. If you are transferring things like small pictures or data files, you probably won't get those speeds. Notice in the chart, small sized transfers are really bad speeds. 64k transfer size is the sweet spot.
If you are not using a device that can read and write at the SD card's rated speeds, your tests will likely show the controllers limitations as the top speed. The slowest device in the file transfer chain determines maximum speed. It sustained the transfers for 2GB without problems. These tests were performed with the microSD installed in a Transcend microSD to USB3.0 adapter and that adapter into an available USB3.1 port on my PC. So my top capability will be that of USB3 which is far above what the card speeds could be. You need USB 3.0 or higher to get near the data speeds. USB 2.X or 1.X will not be able to achieve anywhere near those speeds because the USB will bottleneck the data as the cards are faster than the port. Most older SD card readers on devices also won't attain anywhere near that 100MB/s read speed. That's why I test with USB3 instead of a card reader of unknown capabilities.
This 64G card will not do 4k video well at all. This card is not designed to. For that you must go to their extreme line of cards with the v30 certification stamp. The reason they don't warrant these in drones or dash cams or DVRs is because these cards were never designed for that kind of constant writing. They will work fine with 1080p video 60FPS or high resolution photo taking. DSLR cameras that snap photos in fast succession by holding down a photo type button also might struggle with this card.
Too many people here have said these cards don't meet the speed requirements advertised. I'm telling you that the vast majority of these people have no clue how to test SD speeds and have card readers and testing devices that don't support these speeds. The ad only refers to read speed as 100mB/s, not write speed. The ad doesn't mention the write speed for this card. But on the SanDisk website it says 40MB/s. Most SD cards write speeds are about 40-60% of the read speed if you can't find write specs. That's is why SD cards (and most SSD drives) transfer data out of them (read) faster than they do to transfer data into them (write). If you go to the SanDisk website, (at the date of this review), it showed 100mB/s maximum read speed and 40mB/s maximum write speed in the specs. That's what I verified this card is doing. Also this is an Ultra card, not an Ultra Extreme. Some reviewers have read the specs for the faster card and apply it to this one by mistake of thinking that the slightly different name is the same card. Exact naming and certification stamps and specs other than just the read/write speed are very important when looking at SD cards that can do 4k videos. This Ultra is a type 10 card and is fine for taking photos and HD video up to 1080p 60FPS. It does not have the v30 stamp of approval for 4k video. If you are an owner of any device that does 4k video, don't buy this card. I noticed a huge number of the one and two star reviews were from people who don't understand video, photo, and audio requirements of their device and go to buy a cheaper card and end up disappointed when their device didn't support it. If you are using 4k video devices be sure your memory at least has the v30 stamp or don't buy it for 4k use. If the price of the card is really cheap it's very likely its not top of the line. Do some research by reading your device manual specs 1st. It'll generally tell you exactly what kind of card you need to get. Don't buy any SD memory just because it's cheap. That will almost always get you into trouble.
Understand that this 64G microSD Ultra is formatted with exFAT which is now the industry standard for any SD or USB drive over 32G. You can't have a drive bigger than 32G with FAT32 in Windows. Also FAT32 limits you to a maximum of 4G file sizes. Since almost any lengthy HD video will eventually want to go past that, the exFAT format solves that limitation. Some older devices that record video will only make 4G files then start a new file when it reaches that file size. You then have to put them together yourself. If you use some third party formatting programs that don't use Windows to do the format, they can make bigger FAT32 drives. Sometimes they are then not recognizable by programs that do religiously follow the FAT32 is for only 32G and less rule. So if your device can't understand exFAT you'll have to try some of those custom formatter programs or stick to 32G SD/USB cards in your device if it only knows FAT32 formatting. Many card reader devices haven't been modernized to see an exFAT drive.
I do like the SanDisk memory a lot. I've never got a bad one. I did once get a fake one a few months ago from Amazon. And so I think it's important to discuss fakes. Apparently from the reviews, lots of people have got fake SanDisks and other brand names from Amazon. When resellers like Amazon buy product from several companies at the thousands of parts level, they don't have time to individually check every one of those for authenticity. Especially considering many of these fakes require hardware testing. These fakes either don't match capacities or die within a short period of time or don't perform anywhere near rated levels. Some could even pop the chip or burn it and the controller up. So it's important to spot fakes as soon as possible. Fakes are also often chips that failed the manufacturer's tests, get bought for scrap by an unscrupulous company who then proceeds to relabel and brand them like a large capacity name brand card in order to earn the extra dollars someone would pay for the larger good SD. Since these fakes can be introduced anywhere along the supply chain, they are difficult to weed out unless every item is checked for authenticity. In some countries where these come from, it's not even illegal.
Get some software memory testers or drive programs to test your USB/SD cards. Usually software ones are free or really cheap. Hardware ones will likely cost you $$. If you don't intend on testing a lot of SDs, just get the software testers.
Verify the new chip you got was real by checking capacities and set test loops to test every memory byte over and over for at least an hour before dedicating them to your valuable data. Sometimes the chips that fail over a few days or weeks of time were fake ones. But there's a catch to testing too much. SD drives have a limited amount of times they will write to a location. Sure that's usually hundreds of thousands of times. But if you test a lot, you are also doing writes to the card. So don't test for long periods of time as that can wear out your chips future write-ability.
Also look closely at the packaging before you tear the package open to remove the card. If the print and colors look off or out of focus or smeared, it's very probably a fake. Sometimes it's obvious sometimes it's not. Look for really poor language translation in labels. Sometimes fakes are downright laughable in spelling errors. If its already an open package, it may be fake. The makers of these fake chips insert them into the supply chain to buyers like Amazon. Then the seller to individual customers (like Amazon) generally has no knowledge they are selling fakes as some are real and some are not. The person who sold it to you is the only one you should attempt a refund from. If you do get a fake one, get a refund or exchange from Amazon. Amazon is legally liable to replace them no matter what they may tell you about the item being not returnable. Don't try to do a SanDisk warranty as they will just tell you, you bought a fake and they are not responsible. (And they aren't...It's usually not their fault). Amazon has a responsibility to you but they may want you to return the card and packaging for their own evaluation proof (rare).
Don't just copy some data to the card and call it good. Many fakes are programmed to report the full GB values sold while only having much smaller chips in the microSDc. So lets say you ordered a 64G and really get a fake 2G. The SD might report as 64G but may not format right. Or the first 2G might work fine and then when you go beyond that, it tries to write new info over the top of the 1st 2G of data and corrupts your data. When you see a lot of reviewers say the card worked fine for a week or so and then started to corrupt data, this is usually what's happening. A good memory tester (free software) will check every memory bank with patterns and if any don't pass the tests, it will tell you. You can let them run for a hour or so checking the SDs over and over. Again don't let these tests go on for long periods of time as the testers are writing to memory each pass they make. But you do need to let the testers run long enough to get at least 3 good passes through all the memory.
Don't let the fear of getting a bad SD or microSD scare you away from these products. The vast majority of people getting these have received the real deal. Test your cards in the first days after you get them. Past 30 days and you may be on your own.
I've used and installed numerous microSD cards and SD cards on all types of equipment. I only once got a fake and it was rather obvious. It's rare to get a fake but something you should be aware of.
All the ones I've got from SanDisk perform at the speed they are rated at.
So when you see someone say they can't get the speed rating advertised, its 90% of the time their hardware or ignorance of how to test them. SanDisk is one of the better manufacturers of memory devices and yet remains in the middle on pricing. It's hard to go wrong with SanDisk. This particular 64G card I bought this time is being used in a 1080p/60FPS Sony camcorder. It works great for that resolution and frame rate. I also currently have 4 3D printers that I also use nothing but SanDisk in. The crappy no name memory that came with all those printers failed within a month. Some of the SanDisk SD/microSD cards I own have now been in those printers for years without fail and some were in operation in other devices (like Roku's and such). All nonvolatile memory has a limited number of writes that can be done. So after a while they will go bad. The only way to avoid that is to limit how often you write to them. The more often you write to them the less product life you will have. So if you want your cards to last, edit the files on a system with RAM and hard drives and only send to the SD card when the editing is complete.
Hope that helps some folks trying to consider whether or not to buy these cards.

I got this for my wife's Samsung Galaxy S7 so she could have more room for pictures, videos, music, and audiobooks. She's been using it for just over two weeks and it's been working great. Like most of these cards, it comes with an adapter so it can be plugged into a computer or laptop. I used it once to try it out but I have a bunch of those adapters so after I verified it worked I just threw it the drawer with other stuff I don't use very often.

I bought it to use as extended memory in the little tablet computer i use on the road. Works great. Inserting the small card is a bit like surgery on the computer. But that is not the fault of the card, but has more to do with the design of the computer. So It will stay there. I wont swap it back and forth between different devices. I am considering another one for my phone.

Two years ago, I replaced all my micro SD cards with Samsung EVO cards, because they were half the cost of the Sandisk cards, and Samsung is a reliable brand, right? Well, no. Of the 6 Samsung cards I purchased in 2016, 4 failed within a year. I contacted Samsung to replace 2 of those cards: one failed within 2 months, and the other lasted 27 DAYS before failing. I ended up throwing all the Samsung cards away, even the brand new unopened one I hadn't gotten around to putting into a little-used tablet.
I'm sorry to have doubted you, Sandisk. I now use Sandisk cards only, and this 64GB card in particular is in my phone and my wife's phone. They're not quite as fast as the Samsung cards, but they're infinitely more reliable... which is much more important to me!

Just downloaded the app on to my Android, plugged in the camera, and -- viola!-- was using the camera! Image quality and color are amazing for the price point. I bought this mainly to check my cleaning job on and condition of gun barrels. Does a reasonably nice job imaging a bore. The camera fits into a 22 cal. bore, but the accessories/attachments don't. The image of the 22 is certainly useful without the attachments though.
I read on a forum that gun bore viewing is best if you have a "reflector" of some sort 2 inches ahead of the camera. This unit comes with such an attachment. It also comes with a probe and a hook -- all of which attach solidly to the camera to prevent losing them while in use. I can see using this in drains, walls, engines, etc.
You can capture video and still images with either your smart phone or your computer. It comes with three different USB plugs for versatility.
I can't speak of durability as I just received this yesterday. I will say I already have $20 worth of fun and use out if it.
My only criticism is that the instructions are very thin -- typical of Chinese products; however, it really isn't hard to figure out how everything works.

I started using these micro SD more often now than previously. I have action cam and dslr it just works period. 64gb is the perfect size for both video and photos if plan to mix it up a bit. There is absolutely no delay when shooting back to back photos with this card. I recommend this card for everyday use. Probably not suitable for professional use but pictures of the kids and pets you can’t go wrong here!

I purchased this item to plug into my new 7th gen Kindle Fire. I was expecting to have to manually move all the installed apps to the SDCard like I had to do with my cell phone. I was quite surprised when, as soon as the Kindle Fire detected the new card, it immediately began moving all of the apps that I had installed onto it. This only took a few minutes and I'm quite happy with the result. I have no problem accessing the SDCard using ES File Explorer app, as well as the fire's internal storage.

My wife and I were getting ready for a trip and realized the 16MB micro SD cards we had in our phones were getting low on space. I decided that we would buy new ones and figured at 64MB, this was 4 times what we had and it took two years to fill our original 16GB ones. I ordered two and received them quickly. I plugged these 64GB cards into my computer (has a port to directly plug them in) and Win10 identified it quickly and I was ready to use it. I plugged my Android phone into the computer via USB cable and put it in data share mode. I copied the folders from my 16GB card to the 64GB one and once finished, powered off my phone and removed my old card. New one popped in and powered the phone back up. My phone saw the card and all of my files where there and access through my normal apps (gallery, music, etc.). Then a few weeks later we bought new phones and was able to swap these in from the old phone. Everything was there and they are working great. This is why I save all of my pics, videos and music on an external card. If the phone dies or needs to be replaced, I don't lose all of my data. Definitely would buy again.

Since almost every review I read from the past year stated that people had received a counterfeit SD card from a third party seller, I would just like to let people know that at the present moment, Amazon is fulfilling the SD card orders and the 64 GB microSDXC card I ordered is genuine and works just fine, reporting 59.4 GB capacity (since SanDisk uses the industry standard funny math where they count a GB as the same as a billion bytes which is not true).
I installed it in my Samsung Galaxy S8 cell phone and it was recognized immediately, and then I was able to transfer files to it from my local network via the Android File Manager+ app.
