Review on 📷 High-Speed 64GB Micro SD Card - JBOS Micro SDXC Memory Card, UHS-I, C10, U3, for Smartphone/Bluetooth Speaker/Tablet/PC/Drone/Camera, with Adapter by Derek Wagner

The first thing I do with any new memory card is a memory full test to make sure it actually has space. 64GB cards will always read somewhere in the 59-60GB range, but the important point is that the memory claimed is there and usable. You can also see that the test almost reached the maximum sequential read and write speeds, which I always see as promising. CrystalDiskMark reports show excellent sequential speeds, although random read/write speeds are a bit weak. However, for the intended application of filling an empty card from the camera and then copying the full card to a hard drive, this is sufficient!
