- Reviewed in the United States on December 17, 2017I got this 128 GIG card to use with my tablets. So far it has worked perfectly in my testing. I always keep a couple of spares around for my future buys and I seem to give a lot of my SD cards away to family and friends. I picked up this 128 GIG at a great price and I just couldn’t pass it up.
I own about 100 SD cards and I always do a speed test to verify the reading and writing speeds before I install the memory. This card checked out extremely well. The fastest write speed on this card was 73.143 MB/Sec and the fastest reading speed was 93.368 MB/Sec. I have attached the graphical test data for your information. I used a USB 3.0 port with a USB 3.0 card reader for the test.
Overall, this card worked well and I rated it five stars. If I have any future issues I will update my review.
I hope my review and photo of the test data helps you.
Out of 100 plus SD cards I have purchased from Sandisk I have only had one fail. With Sandisk’s 10 year warranty they replaced it and sent me a new one at no charge. That is the advantage when you purchase high tech from a top company that stands behind their product.
I simply called them and returned the old chip and they sent me a new one.
I am amazed at how well these work and how low the price has gotten on a sale day. Putting one of these into your phone or tablet is a wonderful upgrade to the device’s storage capability.
Almost no one needs a 128 GIG chip but at sales prices you can’t pass up getting them.
This is a great product and it makes your smart devices even more powerful.
This is a simple and easy upgrade for your smart devices.

- Reviewed in the United States on November 2, 2018- I have tried so many different SD cards from various manufacturers, at various price points, in the name of trying to save a few bucks. It was really important to me back when a 128GB card cost $50 or more. They all do the same thing, so what’s the difference, really?
What I've found is that it can be extremely aggravating to put up with when the card does not perform well or does not perform at all. I have heard warning stories about cards that are advertised as one size and actually are another size, causing data loss. With that in mind, I have never tried using the very cheapest card or too-goo-to-be-true card deals. But I have purchased cards on sale at the drugstore or even tried some strange brands. What I have come back to is that it’s just not worth the trouble now that prices have dropped so low. When I am trusting 128 GB of data to a single card, it’s just not worth my time and aggravation to have a card that won’t perform. Furthermore, SanDisk cards like this one are all FAST ENOUGH. I’m not a pro photographer, and I don’t have time to figure out whether a card is Class 1 or Class 3 or whatever. I just want it to be good enough that it can keep up with my devices.
I have now purchased several SanDisk cards, and each and everyone of them has arrived in perfect condition and works perfectly every time. They are faster than any other card that I use and I've never suffered data loss. I am putting this card into my Fiio X5ii Digital Audio Player, and it works just fine. During the initial data transfer I have already noticed that the speed is adequate, and I never experience skipping when playing uncompressed high-resolution audio files. I have the same card for my Nintendo Switch, and it works perfectly.
The prices on these are so good now you have no excuse but to buy good name brand like SanDisk. Just buy it and don't worry about it.

5.0 out of 5 stars Empfehlenswert
Die SanDisk Ultra 128GB MicroSDXC ist eine hervorragende Speicherkarte! Mit bis zu 100 MB/s Übertragungsgeschwindigkeit lassen sich große Dateien blitzschnell verschieben, und die A1 App-Leistung sorgt für flüssiges Arbeiten auf dem Smartphone oder Tablet. Besonders praktisch ist der mitgelieferte SD-Adapter, der die Karte vielseitig einsetzbar macht, z. B. für Kameras oder Laptops.
Die Klasse 10 und U1 Einstufung garantieren eine zuverlässige Leistung für Fotos, Videos und Apps. Für den Preis bekommt man viel Speicherplatz und eine bewährte Qualität, die ich von SanDisk gewohnt bin. Eine klare Empfehlung für alle, die viel Speicher und hohe Geschwindigkeit brauchen!
