Two issues.
1. The original 8GB space will have some firmware on it to run the player. That takes some space.
2. Second, There is a wierd little loophole that memory manufacturers are allowed to advertise, which allows us to have “less” true bytes than we think we should have.
A MB is really 1024 bytes. and a 1GB is really 1024 * 1024 = 1048576 bytes. So for a computer to report 8GB, the actual memory onboard must be 8388608 bytes
Memory manufacturers are allowed to define 8GB as 8000000 bytes. Given this information a computer would see 8000000 bytes as 7812.5 MB or 7.629 GB. And this is before ANY firmware is added.
And due to the math the larger the memory advertised, the bigger the discrepancie.
My 8GB Fuze has a 16GB card. 24GB total right??? NOT… 24000000 bytes is actually computed by my machine as 23437.5 MB or a whopping 22.88 GB.
So its mainly the difference in the way that computers calculate and label memory (binary) and the way humans calculate and label memory (base 10).
Yes, and technically the binary labels (1024) are actually MiB and GiB and called Mebibytes and Gibibytes, which is why manufacturers are allowed to do this - because they are actually selling 8 gigabytes
