About capacity: due to different computing units of hard drive manufacturers and computer operating systems, the capacity display will be different. When producing hard drives, the capacity is calculated according to 1g = 1000m = 1000 x 1000 K = 1000 x 1000 bytes. However, the computer operating system is binary and is calculated according to 1G = 1024M = 1024 * 1024K = 1024 * 1024BYTE. For example: the actual capacity is the characteristic capacity of the hard drive 1000g / 1.024 / 1.024 / 1.024 / 1.024 / 1. .024 = 931g (1000 ÷ 1.024 ÷ 1.024 ÷ 1.024), so the Hard disk display capacity 1 TB is 931g.
