The larger the capacity, the larger the deviation. Storage Industry Area Calculation: 1GB=1000MB=1000x1000KB=1000x1000x1000B Operating System Calculation: 1GB=1024MB=1024x1024KB=1024x10024x1024B Therefore, the storage capacity of 1GB in the operating system is shown as: (1000^3)/( 1024^3)0.93GB 4GB=approx. 3.6GB to 3.8GB 8GB=approx. 7.4GB to 7.6GB 16GB=approx. 14GB to 15GB 32GB=approx. 28GB to 30GB 64GB=approx. 58GB to 60GB 128GB = approx. 110GB to 120GB This is a calculated difference between the manufacturer and your computer.
