It’s just me or you doesn’t know about too?
Okey. Here the difference is well explained. I saw it for the first time in EMC DataDomain interface and it sounded a little “strange”, but ok. Last week a heard a friend talking about and decided to search… What a surprise! haha
In a nutshell, the units as we know them (1Gigabyte = 1000 Megabytes) was proposed by Système International D’Unités (SI) and the other way (1Gibibyte = 1024 Mebibytes, with much more “precision”) was proposed by International Electrotechnical Commission’s (IEC), in 1999.
The main difference is that the first uses 10^x measurement, rather than 2^x (1024 base), like IEC. For example:
For a DVD:
4.7 GB ==> 4.337 GiB
8.5 GB ==> 7.91 GiB
Interesting, isn’t it?
So, again, I suggest you spend some time reading this…
