Extended information

Hard disk capacity: Hard disk capacity is measured in megabytes (MB) or gigabytes (GB), 1GB=1024MB, 1TB=1024GB. However, hard disk manufacturers usually use 1G = 1000MB when nominal hard disk capacity, so the capacity seen in the BIOS or when formatting the hard disk will be smaller than the manufacturer's nominal value.

The capacity index of the hard disk also includes the single disk capacity of the hard disk. The larger the capacity of a single disk, the lower the unit cost and the shorter the average access time. The mainstream hard drive is 500G, and large-capacity hard drives above 750G have also begun to become popular.
