About Capacity :
Due to different ways of computing, or the existing bad block, or some built-in software, the memory capacity of the USB flash drive may show less on the PC. And the more capacity is, the more deviation is.
Storage Industry Area calculation method:
1GB=1000MB=1000*1000KB=1000*1000*1000B
Operation System calculation method:
1GB=1024MB=1024*1024KB=1024*1024*1024B
So 1GB storage in OS shows as: (1000^3)/(1024^3)≈0.93GB

4G = approx （3.6GB – 3.8GB ）
8G = approx （7.4GB – 7.6GB ）
16G = approx （14.0 GB – 15.0 GB ）
32G = approx （28.0 GB – 30.0 GB ）
64G = approx （57.0 GB – 60.0 GB ）
128G= approx （110.0 GB – 120.0 GB）
