That would be correct if 1GB would be 1000MB. Of course, the binary gods ruled otherwise, and decided to make it 1024MB instead
Of course, hard disk manufacturers are on your side, and soon will be moving to defining 1KB as 900 bytes.
You're right (GBs vs. GiBs). I just love computer "science" . Is it memory, bandwidth, or disk space? No wonder everyone wants to just go "unlimited". Sad to say that I've been doing this for a long time and even I get it wrong. I vote for a simplified config file that allows us to specify X MB or X GB so we don't have to think about page size or GiB vs. GB .
