About Capacity:
Hard disk/flash memory vendors are using decimal arithmetic: 1MB=1000KB, 1G=1000MB calculated, but the operating system is using binary arithmetic: 1MB=1024KB, 1GB=1024MB. So there are some differences between display capacity and nominal capacity of hard disk/flash memory products. However, this is allowed to exist. Please do not doubt his authenticity.
8G=approximately 7.5GB, 16GB=approximately 14GB, 32GB=approximately 29GB, 40GB=approximately 37GB, 60GB=approximately 55GB, 80GB=approximately 74GB, 120GB=approximately 111GB, 160GB=approximately 149GB, 250GB=approximately 232GB, 320GB=approximately 298GB, 500GB=approximately 465GB, 640GB=approximately 595GB, 1TB=approximately 930GB
