Increased speed, no increase in cost microSDHC  Class 10 memory cards have higher capacity, but without a higher price, and provide consumers with the faster read speeds of  specification at the price of a Class 10 card. Sequential reads are up to 20 MB/second, and write speeds reach the  speed class 10 specification. Random read and write IOPS are 1400 and 100 respectively. They are remarkably suitable for users who enjoy high definition photography and video recording. Running multiple applications simultaneously causes no loss in read/write speed.
