Extended information:

Storage unit is a unit of measurement. Refers to using a specific quantity or standard as a recording (counting) point in a certain field. Then define another point as a multiple of this point, and the pronoun of this point is the counting unit or storage unit. For example, the load capacity of a truck is tons, which is the amount of goods that the truck can store. Ton is its unit quantifier.

The binary sequence is used to represent the dimension of computer and electronic information data capacity. The basic unit is byte B. The bytes upward are KB, MB, GB, and TB. Each level is 1024 of the previous level. Times, for example, 1KB=1024B, 1M=1024KB.

MB and GB, which are commonly used for memory capacity in the information industry, almost always refer to 2^20, 2^30,... digit groups. KB is also often represented as a 2^10 digit array to distinguish it from kB. Of course, you will often see KB mixed to represent a 2^10 digit array. These representations are not standardized.

As for hard drive capacity, most manufacturers always use decimal counting. Generally, computer operating systems use binary counting, so you will often find that the hard drive capacity you see on your computer is smaller than the actual available capacity on the hard drive. For example, a 20GB hard drive only shows 18.6GB.
