What is the storage capacity of a 10GB hard drive?

A 10GB hard drive means its storage capacity is "10 billion bytes". Byte is a unit of measurement used by computer information technology to measure storage capacity, usually abbreviated as "B"; gb, also called gigabyte, is a decimal unit of information measurement. Hard drive manufacturers usually calculate in decimal places: 1KB=1000B, 1MB=1000KB, 1GB=1000MB; therefore, if you convert "1GB=1000MB=1000*1000KB=1000*1000*1000B", it is 10 billion bytes.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

A 10GB hard drive means its storage capacity is "10 billion bytes".

Hard drive manufacturers usually calculate in decimal places: 1KB=1000Byte, 1MB=1000KB, 1GB=1000MB, 1TB=1000GB.

According to the conversion formula 1GB=1000MB=1000×1000KB=1000×1000×1000B, 10GB=1010B, which is 10 billion bytes.

Byte (Byte) is a unit of measurement used by computer information technology to measure storage capacity. It also represents data types and language characters in some computer programming languages. Bytes are often abbreviated as "B".

gb is also called gigabyte (GB, Gigabyte, also known as jigabyte, gigabyte, gigabyte, halberd, gigabyte in China) , often abbreviated as G, is a decimal unit of information measurement. Gigabyte is often confused with Gibibyte, the binary unit of information measurement. It is often used to indicate the storage capacity of computer hard drives, memories and other storage media with larger capacities.

Note: The gigabyte here is different from what we usually call "GB", which is actually "GiB" (because Windows misuses the information measurement unit of GB, it is displayed in Windows "1GB" should actually refer to "1GiB", but Windows displays it as "1GB", which often causes misunderstanding.)

Actually, 1GB=1000MB=1000000KB=1000000000B . It is different from, 1GiB=1024MiB=1048576KiB=1073741824B (not iB here).

However, the difference in conversion methods between the two often causes confusion. For example, general hard disk manufacturers use the base system of 1,000,000,000 (10) bytes = 1GB, while the conversion formula in the Microsoft Windows operating system is 1 GB == 1,073,741,824 bytes. Due to the difference in the two conversion methods, the capacity is calculated The difference is 7.3%, so it often happens that the capacity reported by the Windows system is smaller than the capacity marked on the hard disk. However, in Apple's OS

Expand knowledge:

Usually the hard drive we buy has a capacity of 1tb and is plugged into the computer It shows about 931G, which is normal. The computer uses binary algorithm. After purchasing a hard drive, careful people will find that the capacity of the hard drive in the operating system does not match the official nominal capacity, and is both less than the nominal capacity. The larger the capacity, the greater the difference.

The nominal 8GB hard drive displays only 7.4GB in the operating system; This is caused by the different calculation methods of hard drive manufacturers and operating systems for calculating capacity, and different unit conversion relationships. . The computer system uses the binary calculation method, while the hard disk manufacturer uses the international unit. In the international unit system, TB, GB, MB, and KB are the counting units of "base 1000". 1000 bytes is 1KB, and every 1000KB is 1MB. Every 1000MB is 1GB and every 1000GB is 1TB.
