Review on 💾 Amazon Basics 64GB microSDXC Memory Card - A2/U3, Full Size Adapter, 100 MB/s (2-Pack) by Ryan Arthur

really very good, CrystalDiskMark gives ratings that are at the level of well-known brands, but I found that the benchmark program is sometimes very misleading, because when copying a large folder with many small files on a micro sd will very often slow down to an excruciating snail's pace, this RevainBasics was no different in that regard, it's elm, but actually even as slow as it actually was B 2-3 times FASTER than others famous brands so overall i would say these are the best 64gb micro sd cards i have.
