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.

For this review, I will be testing with a Transcend RDF8 card reader. This reader tops out at around 93MB/s for sustained reads and writes (short bursts can reach 97MB/s), thus it is not capable of testing the max read speed of the micro SD card, but if it can consistently saturate the card reader across the drive, then it is a good indication of a genuine card.For my testing I used AIDA64 with a linear write test from 0 to 100% fill. I find this to be a better way to test SD cards since it allows you to determine when a card is a fake or using QLC NAND, or very poorly binned TLC where only part of the capacity of the drive will perform at advertised speeds.For reference, I performed some testing using my old 64GB Sandisk Extreme Pro micro SD card that I have confirmed to be genuine, and a key thing you will notice is consistent linear reads and writes across the entire capacity of the drive. The 64GB Extreme Pro has a slower write speed than the 128GB model, thus the true max write speed is measured.Genuine Extreme Pro drives accomplish this by ensuring that the NAND is not a bottleneck for the controller, thus even as it gets full, it can maintain its write speeds.Common counterfeit behaviors are cards that perform fast for a first few GB and then become very slow (Basically allocating part of the NAND in a pseudo SLC mode before you encounter the bad QLC performance). Other methods are taking a decent NAND bin that is a low capacity, e.g., taking a 32GB NAND package and formatting a 128GB+ partition table. In those cases a drive can benchmark well but corrupt all data as soon as you exceed its actual capacity.Genuine reference (64GB Sandisk Extreme Pro micro SD) (I attached and labeled screenshots of the AIDA64 test):Average read speed across the entire drive: 92.7MB/sAverage write speed across the entire drive: 87.5MB/sNext I tested the 128GB Sandisk Extreme Pro micro SD card with the same Transcend RDF8 card reader. As expected, writes will be bottlenecked by the reader.Average read speed across the entire drive: 93MB/sAverage write speed across the entire drive: 86.8MB/sOverall, from my testing the card I received seems to be genuine, and the performance is in line with other Sandisk Extreme Pro micro SD cards. While I am unable to test the full read speed, I am able to confirm that the write performance is consistent with none of the telltale behaviors of low quality NAND.As a final note, fakes will always change. Companies that make counterfeit cards can see examples of genuine ones and adjust their process to match the genuine part visually. What they can’t fake, is the performance, consistency, and capacity all at the same time. Know the limits of your card reader and test within those limits to ascertain whether your card is genuine or not. Counterfeit cards have the most trouble with write performance and consistency, thus longer write tests are most important.For further testing, I used the card in my android smartphone, and it performed very well. Since Android is designed around limiting micro SD card use to tasks which have a lower IOPS demand by default. The vast majority of use cases will be for bulk storage, and saving larger files such as when you record 4K video.The card had no problem keeping up with raw files being captured, as well as 4K video at 100Mbps (well within the write speed limit of the card (which in terms of Mbps, would be in the 700Mbps range)Due to the performance and verification of it being genuine, I rate it 5 stars.

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.

I’m a realist. I understand that there are a fair amount of counterfeit Sandisk cards on Amazon, but since these particular cards weren’t available locally I decided to gamble and test them myself. Normally I’d prefer to purchase them when they’re both shipped and sold from Amazon, but again, no such luck for the 128 GB cards.After testing with H2testw which is a free utility that will write to all of the available card as well as test the read/write speeds I determined that these were in fact legit cards. You can see the results on the two attached pictures. The reason the second picture doesn’t have a write speed is because I’m an idiot and didn’t take a screenshot, so I just ran the second half of the test again. It was similar to the first card.tl;dr: Both cards wrote at about 84 MB/s of their max rated 90 MB/s and read at 130 MB/s of their max rated 170 MB/s from a USB 3 reader, so the cards appear to be legit Sandisk.These were purchased to use while shooting 4K 30 FPS at 100 MB/s bitrate in 10 bit D-LogM on my DJI Mavic 2 Pro drone. Appears to be working just fine. 128 GB is the largest card the DJI Mavic 2 and their Smart Controller is rated to use. I may well buy another to have on hand, though each card should be about 2.5 hours of 4K video.

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.

I purchased 3 of these cards. The first thing I did was test them with f3write and f3read at the bash console to verify their advertised capacities. Fortunately for the seller, the results of the tests confirmed that 60 GiB (i.e., 64 GB) were written and read from these cards. The capacity test is more revealing than the speed test since bogus cards have had their microcontrollers reprogrammed to report larger capacities than what they are capable of.The I/O speed you experience depends on numerous factors and is not a reliable indication of authenticity unless you duplicate the exact conditions that were necessary to report the advertised speeds. For instance, if you plug a microSD card into a microSD to USB 2.0 adapter, 60MB/s is the max speed you will see in either direction even if the card is advertised with a 90MB/s write and 170MB/s read. This is because USB 2.0 is capable of a max data rate of 480 megabits per second which is equal to 60 megabytes per second.f3write and f3read will report I/O averages at the end of their tests. I ran the tests ON MY MACHINE for the three cards I purchased. The average write speed reported by f3write was approx. 60 MB/s and the average read speed reported by f3read was approx. 83 MB/s.The packaging reports a theoretical read speed of 170MB/s and a theoretical write speed of 90 MB/s. You aren’t going to see such speeds unless you have the required hardware and applications. Plugging the card into a microSD to USB 2.0 adapter then attaching the adapter to a USB2.0 port certainly won’t get you anywhere near these speeds.

FINALLY!! after umpteen attempts at trying to buy more storage for my canon, my mavic, my goPro AND my camcorder, i finally found my perfect fit for size and speed. i have tried multiple others and they were all faulty, from incorrect speed writing and incorrect file size – but not this one!! this one was exactly what i have been looking for.i can understand feeling hesitant at spending decent money on these after we have all been burned by amazingly convincing knock-offs, but rest assured these were legit. i’m also just as happy that i don’t have to look anymore for accurate microSD cards.

I bought the SanDisk Extreme Pro MicroSDXC UHS-I U3 A2 V30 256GB Memory Card to use with my GoPro Hero9 Black. So far, I’ve been EXTREMELY SATISFIED with its performance.The SanDisk Extreme Pro is rated at a 95MB/s read and a 90MB/s write speed. However, I’ve consistently seen speeds above this. Attached is a screenshot of one test achieving ~173MB/s read and ~103MB/s write speeds. I use the SanDisk MobileMate USB 3.0 microSD Card Reader (SDDR-B531-GN6NN) to quickly move files from my memory cards to my laptop. It’s been a great combination that works better than expected.The SanDisk Extreme Pro is one of the best microSD cards you can currently buy. If you want to either upgrade your existing memory cards or are looking to pair it with new gear, the SanDisk Extreme Pro is the way to go.

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.

Purchased the 128GB version of this card for use on a GoPro Hero8.Packaging on the card sold by “Amazon” looks genuine so far, but we know scammers are amazing at making thinks “look” original.Testing the card for advertised speeds.I have seen a few reviews here on amazon calling out that the card is not original due to Read/Write speeds of 20 MB/s and under. I agree that if the card advertises more you should get more, the problem here is that the reviewer never states what he is using to test the speed.I have tested the speed with 3 card readers. (Card formatted in the GoPro Hero8 Camera) All Connected to a USB3 on PC.- USB3 MicroSD Card Reader [Results(Read/Write): 95MB/s / 170MB/s]- USB2 MicroSD Card Reader [Results(Read/Write): 19MB/s / 17MB/s]- Included MicroSD to SD Adapter + USB2 SD Card Reader [Results(Read/Write): 17MB/s / 11MB/s].If you use the correct card reader (USB3 type), one capable of handling higher speeds, you will get the results that the card is advertising. (Assuming previews reviewer didn’t take this into account)As for me I can say that the 128GB version of this card is Genuine and performing as it is advertised on the box.Good luck and Thank you for reading.
