The 2nd value is wrong!
8,715MB are 8.5GB - and not 8.7GB!!!

You are wrong.
8715 MB is precisely 8.715 GB.

We had this entire discussion a few weeks ago, and
you can read all about it in the archives.

Probably I wouldnt have answered but in the meantime
I encountered a few more data points:

- Not only is G = 10^9 the SI standard, also the IEEE
decided that 1 GB = 10^9 B, that is, the SI standard
must (by IEEE compliant engineers) also be used w.r.t.
computer memories.

- There is a proposal for a name and prefix notation
for the binary 2^20, 2^30 etc, namely Mi, Gi etc.
Thus, if you want to show off as a real hacker that
cannot be bothered with this decimal stuff, and you just
bought a 17 GB disk then you can call it a 15.8 GiB disk.
See for example, http://physics.nist.gov/cuu/Units/binary.html .
