Quick verdict: For backups and cold data served occasionally, Backblaze B2 is the pick: about $6/TB/month with 3x free egress and no per-request fees at hobby scale. For high-churn data access, Wasabi’s no-egress flat rate usually wins. Both are S3-compatible and honest products.
Backblaze B2 wins on raw storage price and the 3x stored-data free egress rule — unmatched for backup targets. Wasabi wins on access patterns: no egress fees at all and no API request charges, so read-heavy workloads are predictable.
Store 1TB, restore 1TB once a year: effectively free on Backblaze, ordinary cost on Wasabi (already included). Serve 1TB to users monthly: Wasabi flat pricing wins clearly. Match the tool to the traffic shape.
Both speak the S3 API, so rclone, restic, MinIO clients and application SDKs work unchanged. Migration between them is a sync job, not a rewrite.
Backup and archival (restic, Veeam targets, media originals): Backblaze B2. CDN origins and frequent reads: Wasabi.
