A USB flash drive is necessary to store or transport files with you!
Flash memory products are generally shipped as 1MB = 1000KB and 1G = 1000MB, but binary operations 1MB = 1024KB = 1024MB, 1T = 1024GB, and 1T = 1024GB are used for operation. There is a certain difference between the displayed capacity and the standard capacity. These are the calculated differences between us and PC manufacturers.
