Exactly
Decimal — powers of 1000
What drive manufacturers and the SI standard use.
Binary — powers of 1024
What memory, and most operating systems, actually count in.
How long to transfer
Connection speeds are quoted in bits per second, so the byte rate is an eighth of the headline number.
Calculated in this page. Both systems are shown because software is inconsistent: Windows counts in powers of 1024 but labels the result "GB", while macOS and drive manufacturers use powers of 1000. Neither is lying — they are answering different questions with the same word.
