What is the actual capacity of a 1TB HDD, is it 1000GB or 931GB?
I am not asking about the formatted size; the raw/unformatted size. The data sheet says, 1TB HDD is 1 Trillion Bytes, but if you check Google with "one trillion bytes in GB" it says, 931.323GB.
At the same time, Wikipedia says, 1TB is 1000GB and it is the 1TiB as 931GB.
Now I'm a bit confused, actually a 1TB HDD is manufactured as 1024GB or 1000GB or 931GB? or is the 1000GB in SI same as 931GB in binary?
1The "unformatted" capacity of a HDD is irrelevant today, as the disk controller does not allow access to the unformatted drive (anymore). Note that this "formatted" capacity (whether in decimal or binary multipliers) is further reduced by disk partitioning and filesystem overhead. Installing a filesystem is confusing also called "formatting", which is not the low-level media format when HDD manufacturers mention "unformatted" capacity. – sawdust – 2013-05-24T20:05:02.277
