but
" Because the SI prefixes strictly represent powers of 10, they should not be used to represent powers of 2. Thus, one kilobit, or 1 kbit, is 1000 bit and not 210 bit = 1024 bit. To alleviate this ambiguity, prefixes for binary multiples have been adopted by the International Electrotechnical Commission (IEC) for use in information technology."
Here is the web site for the correct units
http://physics.nist.gov/cuu/Units/binary.html
so a giagbyte is a GiB, not a gb, GB. gB, or a Gb.

Ben, when was the SI changed? I was taught that lower case denoted powers to the right of the decimal point and upper case denoted powers to the left of the decimal point.
d = deci or .1 c = centi or .01 m = milli or .001 etc., while D = Deka or 10 C = Centa or 100 K = Kilo or 1,000 M = Mega or 1,000,000
I forget what if any were between Kilo & Mega
Anyway, my Pocket Ref, 2nd ed. by Thomas J. Glover shows (using lower case though):
1 kilobyte = 2 to the 10th bytes + exactly 1,024 bytes 1 megabyte = 2 to the 20th bytes + exactly 1,048,576 bytes 1 gigabyte = 2 to the 30th bytes + exactly 1,073,741,284 bytes 1 terabyte = 2 to the 40th bytes + exactly 1,099,511,627,776 bytes 1 petabyte = 2 to the 50th bytes + exactly 1,125,899,906,842,6204 bytes
Also, now that LaCie is selling 1 TeraByte hard drives, how long before 1 PetaByte hard drives come out?
