About Real Capacity

Capacity flash memory products are usually shipped in accordance with 1MB = 1000KB, 1G = 1000MB computing, but the operating system using binary arithmetic 1MB = 1024KB, 1GB = 1024MB, so there are some differences between the display capacity and standard capacity memory products.

4GB = approximately 3.6GB-3.8GB

8GB = approximately 7.4GB-7.6GB

16GB = approximately 14GB-15GB

32GB = approximately 28GB-30GB

64GB = approximately 58GB-60GB

This is calculation difference between manufacturer and your PC, please Google 'USB Flash Drive capacity' to get more information.
