BIack New 500 GB external Portable 2.5" USB 2.0 hard Drive HDD POCKET SIZE
Hard disk manufacturer:
1KB=1000Byte bytes, 1MB=1000KB, 1GB=1000MB, 1TB=1000GB
operating system:
1KB=1024Bytes, 1MB=1024KB, 1GB=1024MB, 1TB=1024GB
Hard disk manufacturers define MB, GB, TB and other units in a 10-bit manner.
That is to say, under the definition of the hard disk manufacturer, 1MB = 10 to the 6th power (1000 * 1000) bytes,
1GB is equal to 10's 9th power bytes, and 1TB is equal to 10's 12th power bytes;
But under the operating system, the definition used is a 2-digit way.
So the operating system's 1MB = 1024 * 1024 bytes,
See the difference?
Still can't see it? It doesn't matter, you can understand after reading the following examples.
The capacity of the hard disk is calculated in this way.
The number of bytes of the 320G hard disk is 320000000000 bytes.
Equal to 320000000000÷1024=312500000K bytes;
Equal to 312500000÷1024=305176M bytes;
Equal to 305176÷1024=298G bytes.
It can be seen that the displayed capacity is around 298G.
This is the normal normal capacity.
