Have you ever been surprised when you just bought an SSD, hard disk, or flash drive when you just connected it to a computer or laptop, the storage is reduced even though we haven’t used it at all?
Then why the storage is reduced?
The Storage is truncated to a file system partition. Anyways, it’s true that the storage is truncated for the file system which is partitioned separately so it can’t be tampered with. In the past, people using floppy disks had to reformat before they could be used, that’s the function of the file system, separated in a hidden partition so that people didn’t have to reformat it all the time because the file system was accidentally deleted.
For example, when we buy an SSD with a capacity of 250GB which is listed on the package. But when the SSD is connected, the detected size is only 233GB.
Many people think that the reduced size is due to the capacity is taken by the system. But actually, this is not true.
Quoted from the Crucial.com site, the Windows operating system is indeed different from macOS or Linux. Note that Windows calculates 1 kilobyte per megabyte as 1,024 bytes per kilobyte
That’s why because of the different calculations, the size of the storage that appears in Windows will be less than the original size.
While in other operating systems such as macOS and Linux, 1 kilobyte itself is still counted as 1,000 bytes so that the storage size that appears in both operations is still the same and does not decrease.
Here we present a brief explanation of using 480GB storage for those of you who want to know the calculation:
480,000,000,000 Bytes / 1,024 = 468,750,000 Kilobytes
468,750,000 Kilobytes / 1,024 = 457,764 Megabytes
457,764 Megabytes / 1,024 = 447 Gigabytes
With these calculations, here are the storage sizes that appear on the Windows operating system with several sizes:
250GB appears as 233GB
500GB appears as 465GB
1,000GB (1TB) appears as 931GB
2,000GB (2TB) appears as 1,862GB (1,862TB)
