That's very true Mark, but I think this is more about Marketing (making
things look better/bigger than they really are) rather than international
standards vs. maths...

Alternative bias, saying the same thing :-)

How many joules in a gigajoule? How many watts in a gigawatt?

Actually, hard disk manufacturers are CORRECTLY following the
international standards body definition of giga (g) to mean 1,000,000,000=
.

This differentiates them from the stupid IT companies who think that,
just because they use powers of two, it somehow allows them to misuse
internationally recognised terms and put a subtly different meaning on
them.


It's worth noting that SOME companies use the lower-case g to mean 1
billion, and the upper-case G to mean 2 to the power of 30.

On that basis, 128 Gb =3D 137.43 gb

Others, of course, this being IT, use the lower-case G to mean 1
billion, and the upper-case g to mean 2 to the power of 30 :-)
