GB is used as the meaning of 1 billion bytes by storage manufacturers. GiB is 2^30 bytes.
1 TERAbyte = 10^12 bytes (common decimal notation)
1 TEBAbyte = 2^40 bytes (binary notation)
And here Arkanor has shown why a 500GB drive only shows 465GB in Windows. Windows thinks a gigabyte is 1024MB but hard drive manufacturers say a GB is 1000MB. To adjust for the discrepancy, the silly sounding binary prefixes were created although they are not widely adopted. I'm repping you for this!
