Object Storage · decision tool

Cheapest storage for backups

Backups store a lot and read little, so per-GB storage price dominates and egress barely matters — a different winner than egress-heavy media serving. Priced at your volume.

The decision, in plain words

For a solo builder at 2,000 GB stored and a $20.00/mo budget for the object storage slot, Wasabi leads at 74% fit and $15.98/mo. The two rules doing the work: budget fit (~$15.98/mo is 80% of your $20/mo budget); ecosystem maturity (established — our estimate from ecosystem age, docs and hiring pool).

Backblaze B2 is a genuine coin-flip here (73% fit, $13.93/mo, $2.05 cheaper) — read both risk lists and pick the failure mode you prefer.

Honest weak spot of the pick: no free tier — paying from day one.

Generated from the calculation above — every number traces to the sourced data; nothing here is written by an AI making things up.

Why Wasabi scores 74%

Budget fit (weight 30, our estimate) — ~$15.98/mo is 80% of your $20/mo budget+21.03

Batteries included (weight 12, our estimate) — Object storage only — you assemble the rest separately+0

Exit cost (weight 4, our estimate) — S3-compatible API — moving providers is mostly an endpoint + credentials change+3.2

Ecosystem maturity (weight 8, our estimate) — established — our estimate from ecosystem age, docs and hiring pool+8

Egress predictability (weight 8, our estimate) — No metered egress fees — the bill can't blow up when traffic spikes (weight is our estimate)+8

Free-tier runway (weight 10, our estimate) — No free tier — paying from day one-6
