SanDisk 64GB Extreme Pro microSDXC Card U3 V30 A2 170MB/s R 90MB/s W (128gb)

Does its job. Slightly Faster data transfers compared to the normal ones. Storage might not be enough. Simple plug and fit. Recommend only for small devices.

Without second thought you guys can go for it, i have bought it for my gopro 9 as it was getting hot because of other memory card. this SD card is really good

Good write speed ranging 74mb/s to 76.9 Mbps. Read speed is less than half of what's on package 81.4mbps as opposed to 170mbps. Could have as well gone for a much less expensive option of SanDisk Extreme. Available storage is 119GB (as per windows) or 121GB as per (as per the test software). Wonder why companies shouldn't do a quality check before packing these storage devices.

This 128-GB SanDisk microSD card is my 7th and I also bought 5 SanDisk pen drives. It is just the brand's quality and service experience that tempt to buy storage devices from SanDisk. Lets talk about performance, however to get fast speeds system must have right configuration. It never gave 170mbps read/write on my system but still it manages the speed in 140s, which is also good enough. I have to check speeds on other devices as well to check it top transfer speed. But for now after using and trusting SanDisk for so many years, I will definately recommend SanDisk micrSD card.

Very fast and Ver trustable brand and very fast value for money for sure. It's very fast usually for drones

It works very well with GoPro, devices that require super fast writes, like GoPro cams. Tested with 1080p 30/60/120fps recordings. Haven't tested extensively with 2k and 4k recordings though.

Good

After receiving, inserted it into the drone. The drone did not recognize the card. Thought it is a drone issue and delayed checking on it. After few days, contacted Drone technical support and they mentioned it is a supported card. Then ordered a card reader to format it, so that it might start working. After inserting in the card reader, Windows shows that it has to be formatted. But formatting is failing on Windows. By this time, the return window was gone and could not return the product.

Nerdeyse aynı günde geldi. Ben piayasanın çok altında aynı kalite👏🏻🧿

Genuine Sandisk product, never had problem with previous Sandisk SD cards.

ممتاز وسرعه عاليه احسن من بتاع سامسونج بكتير

Ótimo cartão, natal eu no meu drone, deu certo

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/s Average write speed across the entire drive: 87.5MB/s Next 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/s Average write speed across the entire drive: 86.8MB/s Overall, 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.
