Micro SD Card supports up to 100MB/s read speed and up to standard write speed for data transfer. (For devices that don’t support UHS-I, the transmission speed will be different due to interface limitations.)
Micro SD Memory Card supports UHS-I, U1, Speed Class 10, Video Speed Class 10 (V10) , which offer high read speed, fast file transfer speed, smooth as well as continuous photo shooting and Full HD video 720P and 1080P recording. For apps, A1 (App 1) performance is continuous 1500 read IOPS, 500 write IOPS, which helps not only run faster, but also save smartphone’s or tablet’s storage memory.
MicroSD Card supports up to 1.5 hours 1080P video, or up to 5 hours 720P video, or 9,400 photos, or 4,900 songs. (1GB=1,000,000,000 bytes.) (Due to different capacity algorithms and partial capacity are used for system files, management and performance optimization, so the actual available capacity may be less than the identifying capacity.)
