Flash memory vendors are using decimal arithmetic: 1G = 1000MB=1000*1000KB=1000*1000*1000B calculated and the operating system using binary arithmetic: 1GB = 1024MB=1024*1024KB=1024*1024*1024B For example 1GB U disk capacity display: 1GB=(1000*1000*1000) / (1024*1024*1024) So there are some differences between display capacity and nominal capacity of flash memory products If you don’t know much about capacity, please Google U Disk capacity’ to get more information. Thank you for your kindly understand
