About capacity:

Due to different calculation methods, or the existence of faulty blocks, or some built-in software, the storage capacity of the USB flash drive may be less displayed on the PC. And the greater the capacity, the greater the deviation. 

Calculation method in the warehousing industry:1GB = 1000MB = 1000 * 1000KB = 1000 * 1000 * 1000B

Operating system calculation method:1GB = 1024MB = 1024 * 1024KB = 1024 * 1024 * 1024B

4GB = approximately 3.6 GB-3.8 GB

8GB = approximately 7.4 GB-7.6 GB

16GB = approximately 14GB-15GB

32GB = approximately 27GB-30GB

64GB = approximately 58GB-60GB

128GB =approximately 110GB-120GB

This is the calculated difference between the manufacturer and your PC, please get Google “USB Flash Drive Capacity” for more information.
