Attached are two pictures of the CrystalDiskMark, once a Sequential Read / Write Run with 3x 4GB to see how fast the map for larger copying.
The other picture is of a 3x 1GB Read / Write Full Run incl. Seq, 512k, 4K and 4K QD32.
Unlike other people here, I reach nearly given 95 MB / s read rate, repays always more than 75 MB / s. I have used the included Micro-SD / USB adapter with USB 3.0 on the computer.
I also have the contents of my old SD card to the new copy (of course, with a detour via SSD) and have 21,7GB 2080 files can be transferred within 21 minutes and 7 seconds, which is roughly a write average of 17.2 MB / s.
Who also happens to be a Galaxy S4 has: The card reader from the S4 does not support UHS-I, therefore, the performance is much lower there. I've reached 17.90 MB / s read and 13.11 MB / s write performance. For everyday no problem for 1080p 60fps recording it loose enough. If I want to copy something larger, I'll use the supplied adapter. The way, is super small, but is a bit hot at greater copying.
Once I abraucht the map, I will edit this review accordingly, until then there is 4 stars for top performance (currently the fastest 128GB Micro-SD cards prior Samsung / SanDisk) for little money (I got it for 86 at Amazon itself ). 5 stars would have given it if the card would have reached the promised values.
