Unless you are a disk drive vendor, in which case you insist it's 10.

Why? Assuming a byte being 10 bits instead of 8 bits would actually make the drive capacity lower in terms of bytes (of course not physically but for marketing), which a vendor probably doesn't want.

I am not sure what the op is talking about with bytes, but it could be powers of 2 v. powers of ten for kb/mb/gb.

Yeah, that's the kibibytes vs kilobytes / gibibytes vs gigabytes diffence... Which adds up to ~7% difference in capacity when talking about GiB/GB, and even 12.5% when talking about PiB/PB

Kibibyte (KiB)

1,024¹ = 1,024

Mebibyte (MiB)

1,024² = 1,048,576

Gibibyte (GiB)

1,024³ = 1,073,741,824

Tebibyte (TiB)

1,024⁴ = 1,099,511,627,776

Pebibyte (PiB)

1,024⁵ = 1,125,899,906,842,62
