Samsung PRO Ultimate microSD memory card, 128 GB, UHS-I U3, 200 MB/s read, 130 MB/s write, Includes SD adapter, for smartphone, drone or action cam

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.

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.

Works well for drones and for tablets uploads images from drones without stutter

Great product and good value for money.

Very fast micro SD card. Nothing to complain about.

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.

An excellent value fast sd card

good product
