Samsung PRO Ultimate microSD memory card, 512 GB, UHS-I U3, 200 MB/s read, 130 MB/s write, incl. SD adapter, for smartphone, drone or action cam

Excellent, good value for money, good storage capacity, good functionality, good writing speed.

This card is very impressive. For me, write speeds are important as I use the cards for high resolution video at maximum fps. See the image to see the headline statistics - you can see the entire surface map is consistently fast, the slowest being 78.11 mbps, the highest being 137.57 mbps. I had also bought a Sandisk Extreme 256GB and tested it using the same apparatus, in fact I tried two brand new cards. Both showed the surface scan to be dotted with dark green squares and whilst the write speed never dropped below 30 mbps, there were quite a few sectors in the 30s. For the faster sectors, the Sandisk was higher, however it is clear to me that the Samsung card is less erratic and will give more consistent performance. I would therefore definitely buy these Samsung cards over the Sandisk Extreme as I would assume the manufacturing standards are far higher giving rise to the more consistent results.

Fast, reliable, perfect for the job

After a positive review, the price usually increases on Amazon. But I'm making an exception now. I've used many cards from all manufacturers. I have faster cards than this, but this one has performed the best so far in my Samsung phone. I recommend it to everyone, it even beat the SanDisc 200/140 cards in my tests. I'm attaching the results. Unfortunately, I know the price will increase soon...buy it as soon as possible.

Recognised quality item. Reliable and has read and write speeds. Decent storage capacity easy enough to use and compatible with all the kit. I’ve tried it on.

Great thank you 🙏

Great product and good value for money.

Ok

Mon appareil photo Sony ne fonctionne pas correctement avec n'importe quelle carte mémoire SD, mais il accepte parfaitement cette carte Samsung. Cette carte offre un très bon rapport 'qualité / prix' compte tenu de ses performances et de sa capacité.

I have been using this Samsung 128GB microSD card for over two years, and it has worked exactly as expected. No data corruption, no random disconnects, no reliability issues. It has been stable and consistent in daily use. Write speeds feel slow on my camera, but the camera is the bottleneck, not the card. At the time of purchase, this was among the faster options in its category based on both read and write speed claims. In real-world use outside of my camera’s limitations, it performs in line with what it advertises. One of the main reasons I prefer microSD over full-size SD cards is durability. Full-size SD cards have a physical locking switch that can break. When that happens, your data can effectively become locked behind a small plastic design flaw. I have experienced this before and managed to work around it using the tape trick, but I would rather avoid that situation entirely. MicroSD cards remove that mechanical weak point.

Una tarjeta de memoria perfecta para los que buscan estabilidad y buen performance. Además, la serie PRO de tarjetas microSD de Samsung destaca por la durabilidad, lo que supone una confianza ante la pérdida de datos. Recomiendo la compra de este producto.

Great item
