Review: Great performance and capacity when you have a genuine card. - 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.

## Questions & Answers

**Q: People who got a counterfeit from this listing, which vendor?**
A: Counterfeits are possible with all 3rd party sellers, as well as Amazon direct when they mix inventory. Always test the performance, capacity, and consistency of each SD card you purchase. Counterfeits can have inaccurate visuals, while some can look entirely genuine, but what they can't fake, is the performance, especially write throughput over an extended period of time, as the goal of a counterfeit, is to sell low quality and in some cases, lower capacity NAND at high end NAND prices. The easiest way to spot counterfeit NAND, is to do 100% linear write across the entire card. It will not only help to verify the advertised capacity, but it will reveal counterfeit tricks such as using cheap QLC NAND and having the first few GB function in a pseudo SLC mode so that the card will look good on crystal disk mark while being extremely slow when you write more than a few GB to the card.

**Q: Does this work with go pro hero 7? thanks.**
A: Yes of course usually anything with v30(video speed class) is great for video which is 30mb a sec the go pro 9 does like 5 to 8 Mb/s with 4k 30. Also with file transferring like a switch. A3 being even better. 5k If you plan on doing that a lot a lot. You might wanna look at a 60 class.

**Q: Is this an official sandisk microsd card?**
A: Yes, it is authentic.

**Q: Is this a Geniune sandisk?**
A: I am using with my GoPro 7. So far it's working perfectly. Everything indicates that it is genuine.
