Bandwidth Bits vs Bytes

This cluster focuses on corrections and debates over confusing bits per second (e.g., Mbps) with bytes per second (e.g., MB/s) in data transfer rates, often involving the factor-of-8 conversion. Users nitpick units in contexts like networking, storage, and hardware speeds.

I think the OP means 100 MB/s and not 100 Mbps here

agscala • Aug 24, 2015 • View on HN

No, that's actually 0.8 Mb/s

Thaxll • Mar 1, 2018 • View on HN

It's in bit/sec not byte/sec so 8x lower.

amorphid • Aug 7, 2014 • View on HN

Yup, I meant megabits per second :)

haeberli • Jun 29, 2022 • View on HN

Nit: should read: "100 megaBITS"(/second)

rasz • Jun 23, 2022 • View on HN

Both are same (b - bits) number, did you mean MB/s?

kelnos • Apr 2, 2021 • View on HN

That's 10 mega bits per second, not bytes.

drusenko • Mar 3, 2011 • View on HN

Do you know how many Gigabits per second it was?

nusl • Dec 18, 2024 • View on HN

It's 1⁢0^9 bits/s. Your title is wrong.

You might want to check your math :). It's ~10 gbps by both measures.
