What is the real capacity?
Professional U disk Factory , because computer algorithm is different from U disk capacity of the algorithm, computer algorithm 1GB=1024MB ,but U disk capacity of the algorithm 1GB=1000MB,
so there are some differences between display capacity and nominal capacity of flash memory product.
4GB = approximately 3.6GB-3.8GB
8GB = approximately 7.4GB-7.6GB
16GB = approximately 14GB -15GB
32GB = approximately 28GB -30GB 64GB = approximately 58GB - 60GB 128GB = approximately 118GB - 125GB 256GB = approximately 235GB - 250GB
Read and write speed :3-6m / s, read speed: 8-15m /s (transmission speed over a certain relationship with the use of computer configuration.)
