Tips on flash drive capacity: The unit of measurement is not uniform, resulting in data inequality (the difference between decimal and binary) The manufacturer of the U disk refers to the unit of measurement (decimal) of the international standard to indicate the storage capacity of the U disk, that is, 1 GB = 1000 MB. But in the world of computers, data storage is expressed in binary, 1GB = 1024MB. Therefore, after the U disk is inserted into the computer, there will be a phenomenon of "capacity deviation, capacity reduction", mainly because of information asymmetry, and the unit conversion is deviated. So there are some differences between display capacity and nominal capacity of flash memory product: 16GB is about 14GB-15GB 32GB is about 28GB-30GB 64GB is about 58GB-60GB 128GB is about 115GB-123GB ✓ If you have any questions, please feel free to email us.
