Ask HN: Storage pricing: GB or GiB
I am designing a pricing page for our cloud hosting thing. DevOps suggested to use Gibibyte (GiB) instead of Gigabyte (GB) annotation. Binary calculation (GiB) is used under the hood (I believe). I think the actual difference is marginal.
But I wonder if we are doing anyone a favor by presenting it as GiB. Most hosting vendors use the classical metric annotation today:
- DigitalOcean: GiB - Google Cloud: GB - Vultr: GB - Hetzner: GB - AWS: GB - macOS: GB
I see this has been asked before in 2017: https://news.ycombinator.com/item?id=13658889
An open Ask HN community consultation from 2024 where @esher convened hundreds of developers and bootstrappers to share real experiences, hard numbers, and tactics.
Hundreds of active indie hackers contributed case studies, pricing heuristics, and pitfalls to avoid when moonlighting on side projects.
Whatever you use, make sure it's clear what you mean: i.e. the `1GB = 1 billion bytes and 1TB = 1 trillion bytes` type footnote used on sales pages for products with a storage component.
Consider who the target audience is. Technical users will know (or should at least understand if you provide more details) GiB, but non technical users are much more likely to understand GB.

Pick your unit of measurement and use it everywhere.
GB is standard enough and specific enough at that large of a size and most people don't know what the hell a "gibibyte" is anyway.
If you’re metering it, be consistent with your competition or places in adjacent markets.
The risk is you can look expensive to a casual observer if they don’t pay attention.
You should be accurate - charging by one, but communicating pricing by the other is just a road towards conflict with your customer.
