Quote - Oh, and technically speaking 1TB is 1024GB Though I understand that for normal people, (and sneaky hardware OEM's) making 1GB = 1,000MB makes more sense, even if it means being short  changed by a few GB on a drive.

I used to wonder about that and occasionally I'd write about both definitions.

But, sorry, the 1024 thing is officially wrong. The Greek prefixes were abused because 1024 is close to 1000, but it's wrong to do so. A terabyte is officially 1000 to the 4th power. You're thinking of what is now called the TiB or tebibyte.

Officially, the original Greek prefix meanings prevail under the SI system, which is the system officially used to report disk drive metrics.

Of course, all of this derives from the original kilobyte similarty between 1024 and 1000. After all, what's 2.4% error between friends?

Quoting wikipedia:

Historically the unit (kilobyte) has also been used to denote 1024 (210) bytes in many fields of computer science and information technology, because digital system are based on multiples of powers of 2. However, this use has been discouraged by the major standards organizations and a new prefix system was defined by the International Electrotechnical Commission, which defines the kibibyte for this binary multiple.
