TwinMOS’s microSDXC Class 10 UHS-3 is a high-performance memory card designed specifically for smart phones, tablet computers, and vehicle recorders. It features speeds of 40MB/s reading and 10MB/s writing. Thanks to the improved IO access capability, IOPS is able to reach 500 MB/s reading and 150 MB/s writing, exceeding substantially the limits of the same class, enough to satisfy the requirement of smart phones to frequently access small files.
