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).April 18, 2020 (13 month update): card still works great. No complaints, I’m very happy with it.

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.

The Nintendo Switch is incapable of utilizing this SD card to its full capacity. It only supports U1 speeds, and the recent Digital Foundry investigation into the Switch’s loading speeds revealed that using this card instead of a U1 rated one would actually hinder loading speeds, at least while playing Zelda. I say this to tell users that this card is overkill if that’s what you’re buying it for, and you’re better off going for a slower one that the Switch was actually designed to use.This is not the fault of anyone, just wanted to help people become more aware of it.Besides that, the packaging was really nice and well done. The card achieves its rated speeds after testing it using my computer. If you are looking at this for an expensive camera capable of utilizing it properly, look no further.

Just got the card this morning. Speed almost matches or slightly exceeded the rated speed on matching USB reader from SanDisk: 160MB/s+ read, 95MB/s+ write. Performed very decent on built-in SD Slot: 90MB/s+ read/write). Both results from the same laptop: Macbook Pro Late 2013, 2.4GHz Intel i5, 8GB RAM, USB 3.0.I copied over 120GB of data from another card (with dd between two /dev/rdiskx). It sustained 49MBps+ for the *entire* write. The speed was probably limited by the source SD Card.I was running Windows 10 on VirtualBox using the SD as the RAW disk. Windows 10 is fast enough to be usable. (Samsung EVO Pro Endurance was way too slow to be usable, in comparison.)

Do NOT solely judge this card off the speed tests (CrystalDiskMark) for example.The reason being is that it also depends on your card READER!! Yes, you could have a legit card, which i do, but can get 30 MB/s read / write speed, or even 80-90 MB/s. That’s exactly what happened to me when i tested mine to see if it was legit.Testing the speed to see if it is legit is certainly something you should do, but be AWARE that you need to have a card reader that can ALSO reach those speeds. When I first put this in a crappy USB SD card dongle that I had sitting on my desk, I only reached 30 MB/s for both read / write. When I put it in my laptop (which has a nice built in card reader) it only reached 80-90MB/s. It wasn’t until i used the SanDisk USB mate drive that can be packaged with this card (or bought separately) that I achieved the 169/105 speeds.Please don’t immediately assume you have been ripped off with a fake when you get the lower speeds.

Anyone claiming that the green backed microsdxc cards are fake needs to do better research. In all of Sandisk’s marketing, they show a green backed microsd with the “XC” instead of “HC”. In all reviews from reputable websites show the same.Secondly, anyone complaining about how there is missing storage doesn’t understand how marketing of high capacity storage media works. They calculate size based on 1000 kilobyte per megabyte not 1024 kilobyte per megabyte. If you bought the 128GB model, your device would see it as 119GB because your device calculates it as 1024KB per 1MB. It’s been done this way for decades.Here’s a list of most of the capacities that SanDisk sells with their corresponding “actual” size.32GB = 29.8023GB64GB = 59.6046GB128GB = 119.2093GB256GB = 238.4186GB400GB = 372.529GB1TB = 931.3226GBWhen you buy a hard drive, you also don’t get the full capacity for the same reason. This isn’t just SanDisk.Third, the speeds of the card are “UP TO” x and y read and write. It’s highly dependant on what device you’re using it in and even then, those are burst speeds, it’s not intended to sustain that speed for longer than a few seconds.It’s really sad to see an incompetent reviewer up at the top spot when this is a genuinely high quality product.

“1TB Micro SDXC Memory Cards” have been sold online for a handful of years now, by companies with strange, made-up-sounding names like Jojlon, Winston, or Krrttphfff. However, until the SanDisk 1TB Micro SD hit the market this year, every single one of those sellers advertising a 1TB Micro SD card were lying. If you read the comments section of those items (yes, you can still find the bogus, scamming, way-smaller-than-advertised micro SD cards being sold on this website TODAY!) you will see them filled with dissatisfied customers, claiming they were gypped and posting the screenshots of their benchmark software results to prove it. Now, because of this storied history of scammers specifically using this website, and other like it, claiming to sell high-capacity microSD cards, but in reality hocking crappy cards made in China that are, at best, 1/10th the size of what they claim to be, I suspect that a large numbers of the tech-oriented crowd will come across the item in question today: the SanDisk 1TB Extreme microSDKC UHS-I Memory Card (C10, U3, V30, 4K, A2… blah blah blah blah). If a significant percentage of the people who consider purchasing this item get cold feet and back out, due to the aforementioned rampant scamming occurring at the hands of sellers advertising *VERY* large capacity microSD cards, THAT WOULD BE A SHAME!I had significant doubts about the product myself, due to my calculation that there was a high probability this was yet another scam by online rip-off artists. However, I reeeeeeally needed a microSD card bigger than 512GB, for my cell phone. I have juuust about 650GB of high-res music (a lot of DSD files, for example) which I like to carry around in my phone, and this meant that, for me, the highest-capacity-microsd card-available-to-date, the 512GB, simply wouldn’t cut it. I saw the 1TB SanDisk appear on Amazon a week or so ago, but it was not yet available for purchase. Then, a few days ago it officially became available for purchase, and I immediately paid the $450 and, thanks to Prime, selected FREE One-Day Shipping for it.The next day, after I received it in the mail, I immediately put it in the USB adapter it came with, plugged it in to a USB 3.0 slot on my laptop and oppened CrystalDiskMark6, followed by ATTO Disk Benchmark, and, one by one, tested the capabilities of this microSD card. The card’s manufacturer claimed 160MB/s read speeds, and 90MB/s write speeds. I guessed the card would not live up to those claims, as in my experience cards almost never live up to their manufacturer’s claims about their capabilities. So what were my results? You can check them out yourself from the pictures I uploaded.First, the CrystalDiskMark6 tests:At the 50MB size and 1GB size for the test file, for reading speed the card actually reached the manufacturer’s stated speed (nearly), and then outperformed that speed on the second test, while on the writing test the card excelled above the manufacturer’s advertised speeds. Specifically, during the Seq Q32T1 test, the card Read speed was 147.2MB/s and 166.1MB/s for the 50MiB and 1GiB test file sizes, respectively. The Write speed was 103.4MB/s and 104.6MB/s, respectively! That’s a shock, for me, I was NOT expecting a card to actually live up to, and then SURPASS a manufacturers claims.NOTE: the third CrystalDiskMark6 test results are much less impressive. “What happened there?” you might ask. Well, if you take a close look you’ll see the test file size in that case is 32GB. Thats GIGABYTES. 32GB is the largest test file size the program can do, its maxed out at that point. Considering the mechanics of how microSD cards work, the concepts of allocation unit size, etc, its no surprise at all that the card failed to perform well with a test file size of 32GB. MicroSD cards were simply not meant to be used as devices with allocated unit sizes of such a significant size. Its an unrealistic and useless test, that does not help convey any relevant information about the product. I only included it to show the full range of test results obtained from both extremes and the average of the variables available for users of CrystalDiskMark6 to alter.Second, the ATTO Disk Benchmark test results. Above I have listed sequentially the transfer rate results for the card with test file sizes of 64MB, then 128MB and 256MB, all expressed in bytes, and the transfer rate results for the card with test file sizes of 64MB, then 128MB and 256MB expressed as inputs and outputs. Again, we see that the card, at its best, is able to consistently reach Read speeds of approximately 160MB/s, and, I’m happy to report, Write speeds consistently touching 100MB/s! Or VERY close to it, anyways. The point is its significantly above the stated 90MB/s claimed by the manufacturer.All in all, I’m happy. After testing the card and putting it through the proverbial wringer I feel it lives up to and surpasses my expectations in terms of its performance and capabilities. I have now put about 600GB of data, mostly music files, onto the cards and it works flawlessly so far. I have not yet had any issues with file corruption, and the item seems to be durably manufactured. It also comes with a free backup/rescue program download, called RescuePro Deluxe, so that’s a nice addition.TAKEAWAY: If you have the need for a microSD card larger than 512GB, and you can afford the $450 sticker price, GO FOR IT.You can keep an eye on this review, if I have any problems with the card in the future I will add my critique at the bottom as an “EDIT:”

I purchased 4 of these to use in my GoPro Fusion and GoPro7 cameras, and I couldn’t be happier. Not to mention that the price was right!!

I love the product been working perfectly since the day I bought it. I bought this specifically for my Nintendo Switch. I previously had the 512GB Micro SD Card but quickly ran that up, so finally this card went on a discount and I was able to buy it!!!Am glad I did I finally have ALL my games on my system, no more having to delete a few here and there to make room for the next game, finally I can just sit back and Buy/Download just about anything I can get, worry free of weather or not I have enough space!!!!After the format I believe I was left with around 953GB and as of now am left with 75.8GB TOTAL left (Including System Memory), which is still very good at least to me since most games are 2 to 8 sometimes 12GB depending on the game.Anyway I have a total of 176 Games the range from huge AAA games to small Nindies (Nintendo Indies) games as well, and again am very happy with my purchase. Also you can see my current inventory of games in the pictures for better idea of what games

I got this card for my galaxy S9. It had a very good chip installed in it before (Samsung 256G Evo Select) which I liked. But I wanted to max out my S9 both in its 400G max capacity and in the speed to record. This chip/card does record 1080p 60fps with no problems at all. It also does 4k video well. (I tested it in one of my cameras.)The only place it fails is when I’m doing rapid burst pictures in my phone. The camera says it can’t do rapid burst when using an external card and switches burst control over to internal memory automatically. But to be fair the Samsung chip I had did that too. So apparently it’s something built into the camera app or S9 hardware path that just assumes no external chip can do it, even though both the original Samsung 256G and this even higher spec Sandisk 400G are top of the line spec wise. Not really a problem for me as I don’t generally take bursts of photos but mentioned it here in case you do. Frankly, if I needed that, I would get an SLR camera instead of using my phone.When I tried this memory in my Sony video camera, (which is only supposed to support 256G), it saw all 400G and it worked flawlessly and I filled it with combinations of pictures and videos.I also tested this card as an external chip in a USB 3.1 adapter with my computer. It showed 155MB/s read and 88MB/s write at 64k transfer sizes for a duration of its entire 400G. That’s close enough to its listed max speed and I’m happy with that. Now you need to understand, that’s testing with all conditions being nearly perfect for this chip. It’s highly unlikely to perform that good in the real world moving your data around. I noticed that if you go below 64k file transfer sizes or don’t use high speed ports like USB 3, you see much less speed. Most newer cameras and phones will best utilize the higher speeds. But if you use this card with older SD adapters or USB 2.x or computer SD card readers you’ll be disappointed with any fast SD memory card. ALL the pathways through adapters and ports and cables and hardware have to support the higher speeds or testing will just show you the top speed of the weakest link in your data pathway.But let me tell you this card is amazingly fast to copy files to or from if you have the proper equipment to support it!When I got this chip, I first removed my Samsung 256G and installed this card instead (blank). Although it showed up right away as 400G in the S9 phone, I had the phone reformat it anyway as I just like to be sure its setup by the particular device before testing.I then used a USB3.1 adapter to plug the phone into a USB3.1 port on my computer. I already had done driver setups for this phone before.I decided to fill the 400G card with music videos and some personal videos and my docs and my sound files and music. I setup a single copy from the PC to phone external memory of about 340G. (The card actually formats to 367 computer G even though that’s 400G of real memory.) Last time I did 256G like this, it took me few hours to complete. So I started the copy to the phone and walked away thinking I’d come back in several hours or if I heard an error beep. I did notice it was copying files fast.After about an hour and 15 minutes, I heard a bleep from the computer saying it was done. I was a bit frustrated because I thought I was hearing an error beep. So I began to check where in the copy had died. What I discovered was, it really had copied all 340G in 1.25 hours! I couldn’t believe it and rechecked to see all the files were indeed there! That’s including almost 200,000 photo files that usually slow down backups or restorals to a crawl. Never had a write of major data speeds be so fast!So in case you can’t tell by now, I love this card in my Galaxy S9 phone. I was happy with the Samsung 256G memory card but thrilled even more by this Sandisk 400G upgrade in speed and storage size. Granted, I have 6TB of media storage alone on my PC that I’ll never get all of on a phone. But now, thanks to this card, I’ve got all my docs, sound files, music videos, and unwatched videos ready to watch on the phone. Couldn’t be much happier with this Sandisk 400G Extreme microSD card.One thing you should be aware of though is you will definitely use your device battery up quicker with this card installed. It sucks my Samsung Galaxy S9+ battery down about 40% faster the the 64G internal memory by itself. But even then, it still stays up most of the day and night before charging. Of course if you do a lot of copying or moving files, it’s likely to last slightly less without recharging.Update December 2020:This card is still working great for me and it was transfered to my new LG Wing phone. This card is used heavily and still going almost 2 years later. Was a very good buy!
