About Capacity
Hard disk 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 products.However, this is allowed to exist,please do not doubt his authenticity.
80GB≈74GB/120GB≈111GB/160GB≈149GB/250GB≈232GB
320GB≈298GB/500GB≈465GB/750GB≈689GB
