Does What It's Supposed To

I had purchased a Micro SD memory card for my new Akaso action camera only to find out when I tried to use it that it wasn't compatible. (In order to shoot video in 4K the card must be rated as Class 10. The card I previously had bought was not.) Returned that card and bought the SanDisk Extreme Pro SDXC UHS-I U3 A2 V30 and. so far, it has lived up to the hype surrounding the Class 10 rating.

I received the product as advertised and it works. Pics included of package.

Greetings 😊, I received my order in two days real quick so I was very happy about that when I thought it would take longer. I didn't include pictures of the Extreme Pro Micro SD Card because it's in my phone. It looks just like it does in the picture, but you can take a look at the other one that I bought at the same time which came in the same package. I wanted to show what it looks like with it's package because I believe that is important to include which companies rarely ever show in their pictures. The package of the Pro version came with the adapter and the micro card as pictured and as described with functioning. I bought this for my Samsung Galaxy S8+, and I'm sure it will work on any device that can take a micro sd card. I wanted to make sure that it wasn't malfunctioned by saving something from my phone onto the sd card, removing it from my phone, placing in adapter, inserting in my laptop sd card slot, and reading it from my computer, making sure what I saved was indeed there (and it was), reverse checked by putting something else from my computer in the sd card, removing from computer, inserting sd card in phone, and reading to make sure what I copied onto the card was there. So far so good.

It's fat, it's fast, and it doesn't overheat.

I decided to try using microSD cards with USB adapters, because the high performance thumb drives I tried all had issues. They either got very hot in operation, or they occasionally stalled (in order to cool down, I'm guessing). The experiment was a success. Using the included SD adapter and a microSD-to-USB3 adapter, I can use this on computers that don't have SD slots, or only have one, when I need to copy data from one card to another. NO issues with overheating. NO issues with slowing down or stalling.

Completely original and very fast reading and writing speed.

After several time seeking a good and original SD card I found this one and after buying it, I was expecting to receive it and open the box in order to see if this memory card would be original or fake but now I can say, it is completely original, not a fake, the rate of writing speed is about 75 - 90 Mb per second, depending of what kind of card reader speed is, but it is completely original, writes very fast, and reads very fast too.

Replacement card is exactly as described!

Update: Like it says below I received the wrong card at first but the second card is exactly as described and works perfect. I believe it to be a hundred percent genuine and I've changed my review to five stars! I ordered an Extreme Pro and as you can see from my picture what they sent was a plain Extreme card. That's not only not what I ordered but it won't work and now I'm screwed this weekend unless the 2nd one I ordered with next day shipping turns out to be the right card. If it does I'll come back and change this review to reflect that. If it doesn't I'll also come back and let everyone know that as well. Buyer beware... maybe!

Fast and reliable.

Use extreme pro cards in my cameras and phones. This purchase was a 128gb A2 for a new Samsung s9+. Had to remove and install about 5 times to get the phone to recognize it. Pretty sure that was the phones daily. Actually installed in another phone and reformatted the card. Then it worked in the phone it was intended for. On recognition I moved 1600 photos in about 30 seconds to the card and all other phone data. This card has no problem recording 4k and no issues handling anything the S9+ can do. Ordered a 256gb card as well for my own S9+. I'll add that to the review after we use them for a while.

Fast and works great

I tested both cards I purchased and they were close enough to their advertised speeds. I purchased these cards for my kids 2017 vintage Fire HD 8 tablets. These cards speed up all games / apps that were stored on their cards. We still get crashes from new games that run the tablet out of RAM but we no longer have horrible lag while playing games / using apps that require a high amount of read/write to the games / apps on the SD card. I also wanted to have a SD card that would last a while and be relevant if we wanted to buy them new tablets in the next couple years! Highly recommended!

Blazingly fast 400GB micro SDXC card in UHS-1 Interface!

Speed and storage capacity was very impressive in UHS-1 interface. It's compatible with most devices that supports micro SDXC with UHS-1 such as smsrtphones, tablets, drones, Nintendo Switch, cameras, you name it. It comes with 170MB/s Read while 90MB/s Write. Keep in mind that storage and performance may vary depending on host device. For instance, installing 400GB micro SDXC card reports storage capacity as 366GB due to binary format from operating system, though micro SDXC was stored in 400GB via decimal format as advertised. In addition, I have also tested on my Nintendo Switch, storage capacity still reports as 366GB due to binary format which there's nothing you can do due to binary format from operating system. As far as performance goes, I was able to record 4k footage no problem on my Samsung Galaxy S9+ Android Smartphone at either 30fps or 60fps with no frame drop, no degredation, image quality wise looks clear, and read/write performance was consistent too. Pros: 170MB/s Read & 90MB/s Write, thanks to its proprietary Western Digital technology, in collaboration with SanDisk - 400GB storage capacity -Comes with adapter -Compatible with smartphones, drones, Nintendo Switch, tablets, high speed camera, etc. -X-Ray proof, Shockproof, Waterproof -Faster performance in reads/writes with no degredation, no errors, recording quality was consistent, faster browsing apps, load images quicker, no frame drop in 4k resolution, etc. Cons: -It comes at a price of $299 which you are paying premium for better performance and more capacity -Supplies may be short due to high demand and it's brand new too Verdict: Coming from Samsung Pro 64GB micro SDXC, it was massively a huge upgrade to jump from 64GB - 400GB with blazingly fast performance in UHS-1 interface. I did ordered from the seller named Fineline Trading on Amazon US and was fulfilled by Amazon US. From that, it took 2 days to ship from Oregon to California via USPS, and finally was delivered to my mail locker from USPS. The package was in like envelope bag or whatnot. As a result, the package was intact, no bent, no scratch, no damage, no nothing. But overall, I'm very happy with my purchase for an upgrade. If you're looking for new micro SDXC card UHS-1 with faster performance & capacity, then I recommend SanDisk Extreme Pro 400GB UHS-1 micro SDXC card including adapter.

For GoPro Hero 7

For 4k video these are a must. Got mine for $119. I would love the 400GB one but just can't see myself shelling out that much money. 256GB is large enough. Works like a charm in my Hero 7 Black.

Trailblazing

After running these cards (03 x 64 GB) through battery of tests, With 4000 read OPS, 2000+ write OPS I have come to the conclusion that these are possibly the fastest UHS-1, V30 card in the market. And at under $35, they are total Value for money.
