The Object Storage Market Map: 27 Providers, Priced

I mapped the object storage market: 27 providers across seven categories, with the same three numbers on each one. What a terabyte costs to store for a month, what it costs to read back out, and what it costs to write in.

Storage prices turned out to be boring. Everything sits between $6 and $25.50 per TB per month, a 4x spread, about what you would expect from a commodity.

Egress is the weird one. Google charges $120 per TB to hand you your own data back. Cloudflare R2 charges zero. There is no ratio between those two numbers, and it is the line item that sets your actual bill.

Ingress is free at all 16 cloud providers on the map. Nobody charges you to give them your data.

So the number at the bottom is the one that rarely appears in these comparisons: what it costs to walk out with 100 TB. Google Cloud wants $12,000. AWS wants $9,000. Oracle wants $765, because the first 10 TB out each month is free. Backblaze B2 and Cloudflare R2 both want nothing, B2 because its free egress allowance is three times whatever you store, so a full evacuation fits inside it.

Two surprises. MinIO's community repo is archived on GitHub now, which quietly reshuffles the whole self-hosted category. And not one enterprise appliance vendor publishes a per-terabyte price, which tells you what kind of purchase they think it is.

Every price was checked against the provider's own pricing page in July 2026. Where a public number does not exist, the map says so instead of estimating one.
