I got a terabyte drive, I got 1024*1024*1024*1024 bytes errrr ah yes 1099511627776 bytes. Now there's an easy number.

There is no added value in using powers of 2 to represent file size or disk sizes, so why use it?
NIST and IEEE 1541: powers of two = first 2 letters closest SI designation + bi.
kilo, Mega, Giga, Tera = 10^3, 10^6, 10^9, and 10^12
Kibi, Mebi, Gibi, Tebi= 2^10, 2^20, 2^30, and 2^40 respectively

1 terabtye=1x10^12 bytes
1 tebibyte=1x2^40 bytes

kilo, Mega, Giga, Tera, etc are SI prefices that unambiguously refer to powers of 10. Any other assumed definition are completely nonstandard, and used only in colloquial speech.

get it?
