Update 24.2.2019 I make a test with 2 different apps. It looks like the read and write speed is only 20-30 MB/S
I'm thinking this is not original Sandisk

Update 24.2.2019 I make a test with 2 different apps. It looks like the read and write speed is only 20-30 MB/S
I'm thinking this is not original Sandisk



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.

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.

"Für Karten mit 64 GB bis 400 GB: Bis zu 170 MB/s Lesegeschwindigkeit; erreicht dank proprietärer Technologie eine höhere Geschwindigkeit als die UHS-I-typischen 104 MB/s (nur in Verbindung mit kompatiblen Geräten).
Die meisten Kartenelesegeräte können im Moment die Gechwindigkeiten der A2 Karte nicht unterstützen.
Die neueste Card Reader Technologie unterstützt zum Beispiel unser Mobile Mate 3.0 (SanDisk SDDR-B531-GN6NN MobileMate USB 3.0 Reader) Bis zu 170 MB/s Lesegeschwindigkeit; erreicht dank proprietärer Technologie eine höhere Geschwindigkeit."
Soweit ich das verstehe gibt es keine Leistungssteigerung ohne proprietärer Technologie (Könnte SanDisk deutlicher hier anführen), was bedeutet, dass die beworbenen höheren Geschwindigkeiten in Smartphones, Kameras, Konsolen usw. nicht genutzt werden können, da sie sehr wahrscheinlich die spezielle SanDisk-Technologie nicht verwenden.
Etwas dreist dann mit A2 zu werben, wenn in den handelsüblichen Geräten nichteinmal A1 erreicht wird.
Keine Kaufempfehlung von mir.
meine Wahl:
SanDisk Ultra. Unglaubliches P/L-Verhältnis
SanDisk Extreme/Extreme Plus kaum langsamer als die Pro, jedoch um einiges günstiger
Ürsprügliche Rezension:
Entwerde habe ich ein defektes oder gefälschtes Produkt erhalten oder hier wird gemogelt und gehofft niemand merkt es. Die neuere Version der Sandisk Extreme Pro (64GB) ist laut meinem Test langsamer als eine Sandisk Extreme (ohne Pro), die um einiges weniger kostet.
Weiters möchte ich noch auf die sequenziellen Lese und Schreibraten in den folgenden Messergebnissen hinweisen.

Auch ein Test mit echten Daten (bunt durchgemischt, groß und klein) zeigt, dass die Sandisk Extreme Pro langsamer ist.
Ich habe bereits die A1-Version bestellt und warte bis die A2-Version verfügbar ist und teile weitere Testergebnisse mit.
Derweil rate ich dazu die billigere Variante zu wählen.
Ich hoffe ich konnte jemandem damit helfen.

But this card is far from perfect, upon testing on different phones, it seems the card can't write above 30MB and for read its 80MB.
The devices I tested this memory card with are, galaxy note 8, galaxy s7 and i7 hp laptop with adapter and it seems the card is not as great as it is advertised.
Compare to this extreme pro, my other extreme memory card is much faster, that can achieve 90MB read and 85MB write which is much better than what this card can achieved.
For anyone interested in this memory card, avoid this and get the extreme memory card instead.

En effet si votre appareil accepte la norme SDXC pour les micro SD, cela veut dire qu'il peut prendre en charge les cartes jusqu'à 2 TO (voir Wikipedia sur les carte SD pour en savoir plus)
mais :
je conseil de ne jamais faire une course à l'armement pour ce qui est des supports mémoire , ce n'est pas la peine d'acheter ce qui se fait de mieux car le prix et la capacité change tellement vite que les prix se divisent par 2 presque tous les 2 ans.
Il est aussi important d'acheter chez un vendeur reconnu ( et non pas marketplace, donc ici prenez vendu et expédier par amazon pour éviter les mauvaises surprise ), il y a trop de contrefaçons dans le domaine des cartes mémoires, il faut aussi savoir que même en achetant une carte chez un vendeur reconnu on est pas à l'abris de mauvaises cartes.
C'est arrivé pour ma part chez lexar et sandisk, donc aucune marque n'est à l'abris, la plupart des marques offre un remplacement à vie, donc il ne faut pas hésiter à demander un remplacement si cela est possible.
-----------------------------------------
ATTENTION :
AUCUN constructeur ne garantie les données !!!!!
-----------------------------------------
Voilà pourquoi il faut vite faire le remplacement si vous voyez des erreurs de lecture (c'est rare d'avoir des erreurs d'écriture)
La meilleur façon de tester une carte pour le commun des mortel est de charger des fichiers vidéo et de faire des lectures au hasard sur le fichier avec un lecteur, si a un moment donné le fichier se lis mal ou pas du tout, alors que celui ci fonctionne sur d'autre carte, alors la carte à des problèmes, et il faut mieux la changer de suite et ne pas attendre.
Je viens de faire une récupération de données sur une carte corrompu de 128 giga, il m'a fallu 15 heures d'analyse et autant pour copier les fichiers trouvé, comme les fichiers corrompu sont aussi copié , sur un total temporaire de 9438 photo, il y a 694 fichiers corrompu, on peut donc dire presque 10 %
Si vous êtes prêt à perdre 10 % de vos photos, vidéo ou autre, vous n'avez pas besoin de faire attention, sinon je vous conseil ma méthode, cela vous évitera les prises de tête de savoir si c'est la carte ou le périphérique qui marche mal.
