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.
