I got a USB flash drive of 8 GB, and it has just a pinch
over 8 x 10^9 bytes. I know magnetic disk GB are so,
but since the flash is solid state, I would expect that
it goes in powers of 2: 1024^3.
So where is the missing 7% of storage?

Storage capacities are quoted in base 10, not base 2, as per the
current SI standards.

Old farts (me included) expect base 2 numbers but the standard changed
over 10 years ago...

Nope, flash ram isnt organised that way.

There is no missing 7%

Repeat after me: Storage sizes use SI prefixes.

It has allways been that way. There is absolutely no
storage missing from your device.

Incidentlially this is not only legal, but usually
required by law.

I have never learnt about this until I wrongly answered a question
in a test. :)
