| Bottom line | From its public pages, Backblaze B2 has the lowest list price in our 1 TB scenario, with free API calls, egress free up to 3x storage and solid data protection. Each account sits in one of 4 regions, with one storage class. | From its public pages, Cloudflare R2 removes the egress fee and keeps billing simple, with a permanent free tier and no minimums on Standard. Versioning, the S3 Object Lock API and replication are not implemented, so it suits serving data more than strict retention. | From its public pages, Google Cloud Storage has nearly every protection and compliance feature we score, publishes every price in USD and keeps a permanent free tier. Internet egress, billed per GiB, is the main cost, and S3 support is an interoperability mode. | From its public pages, Wasabi sells hot S3-compatible storage at one flat $7.99 per TB a month, with no egress or request fees and retention locks no one can reverse. The 1 TB minimum, the 90-day duration and the fair-use egress rule decide whether it fits. |
