I'm throughly confused, where does the "extra" data come from with GiB if a bit is always a bit... does it start at the byte? How is the byte different that you end up with 24 extra gigs? I might be too tired for this one. Are they the exact same size but GiB has inflated numbers that aren't real? Can someone explain this to me like I'm addicted to Clair Obscur and I'm loosing chunks of sleep to play that game. 🙃 please.
Is the polling options accurate to the storage on a launch PS5 at 667.7 GB?

There is no extra data, it's just a marketing ploy.
Computers work in bits, on or off.
1 byte is 8 bits
RGB color is 3 bytes or 24 bits color
1 KB is 1,024 bytes (2^10)
1 MB is 1,024 KB
1 GB is 1,024 MB
And so on.
Now instead of selling a 1 TB drive as containing 2^40 bytes, which is 1,099,511,627,776 bytes, HDDs get away with 1,000,000,000,000 bytes and call it a TB. Converted back to computer GB or GiB, that's 931 GiB.
It's the same with your internet connection advertising in Mbps.
100 Mbps in computer terms would be 104,857,600 bits per second or 13,107,200 bytes per second (divide by 8), 12.5 MiB per second. (divide by 1024*1024) Instead you get 11.92 GiB per second. Not only do they make it seem bigger by advertising in bits, also using the decimal system.
Thus 825 GB is equivalent to 768.3 GiB
Now it all depends on whether the advertised file size is in GB or GiB.
Anyway memory still uses the correct measurements, if you buy 32 GB RAM, you get 32 * 2^30 bytes, or 32 GiB.
Any other storage you buy uses base 10 nowadays. A 32 GB USB stick is only 29.8 GiB. (I've hit that problem before, why won't this file fit...)
It's just that computers work with a base 2 RAM bus, 256 bit RAM bus, which does not allow going base 10 with RAM as well. RAM needs to stay addressable in base 2, can't cut corners there.
