300 _GB_ is the correct naming, as the prefix Giga meaning 10^9 is

I think a byte is always 2^8, no matter what. So, a GB referenced as
(2^8) * 10^9 sounds kinda odd, especially when you historically talk
about kilobyte as 1024 (2^10) and a megabyte as 1024*1024 (2^20). =)
Yes, it sounds odd, but nevertheless, it is the correct usage now (IEEE
1541). The "classic" G (GB) in computer parlance has changed to Gi
(GiB, to diferentiate from the G prefix as used in all the rest of
units in the SI.
The byte remains the same. The change is in the prefixes. "Gi" is read
"gibi", meaning 2³?. "G" means 10?. This way there is no ambiguity.
That is fascinating. I wasn't aware there was an actual change. I just
figured the hard drive manufacturers were just trying to pull the wool
over our collective eyes.
So, now my memory management documentation is all wrong? I no longer
have 4K of memory in my TRS-80? :P
