Is 1TB Equal to 1000GB or 1024GB? Understanding Hard Drive Capacity Units

Question

In a Saturn ad, I came across a 1TB hard drive.
In the description below it stands:
"Capacity 1 Terabyte (1000 GB), speed 7200, etc."

Here's my question: is the description true? I mean those 1000?
I am asking for a comprehensive explanation

Well, in general, since 1G is 10 ^ 9, and 1T is 10 ^ 12, it is generally correct .. ( Link Unless you take the correction that, for example, 1kB = 1024B, because it's actually not a kilo, but a fan when it comes to the amount of information ...

Generally speaking, the problem is that salespeople and marketers use a multiple of 1000 to size hard drives. In computer science, on the other hand, a multiple of 1024 = 2 ^ 10 is used.
And hence it follows, for example, that the disk by the merchant referred to as 500GB will actually be reported as 465.66GB after being installed in the computer.

well, that is, according to this table

there is no error in the error notification, right? The announcement says TB, which is 1000GB.
However, if the advertisement mentioned disk 1 TiB in brackets it would have to be (1024) - Do I understand it correctly?

It will be another matter that there will actually be less space available to the user, because if you take into account these prefixes kibi, gibi, etc., it will turn out that 2 ^ 40> 10 ^ 12. I would say that the use of decimal prefixes for rounding, for convenience and habit. The fact that it will not equal 500GB may be due to the fact that some memory is probably used for some boot sectors - I don't know exactly, I don't know.

let's not fight for those 24 - I'm not going to buy this disk or expect to squeeze out all of the declared memory from it. The dispute was only about the correctness of the recording
1 TB = 1000 GB
Summing up, I understand that this is the most correct notation, although very badly applied. I understand that in relation to the disk, the recording should
1 TiB = 1024 GiB
If I am still wrong then please slower and in uppercase

I heard that 1GB is 1024MB but 1TB is only 1000GB and the next multiples in IT are the same as in TB.

wojtusp7 · Answer

In computer science, multiples of two are given, i.e. binary (binary) prefixes are used
1GB = 1024 MB
1MB = 1024KB
1KB = 1024B
1B = 8b
There is probably nothing difficult. Generally speaking, 1 GB is 1000MB.
There is not much difference and it is more convenient

However, manufacturers of hard drives give the capacity of their products godly, that is; 1 TB = 1000 GB 1 GB = 1000 MB , etc.
