Indicative rates (2026, EU region; check each provider for the exact figure). Data upload (ingress) is free with every provider. ¹ Wasabi: 90-day minimum retention (early deletes are still billed) and free egress under a fair-use policy (must not exceed what you store). ² Backblaze B2: egress free up to 3× your stored data per day; beyond that ~€0.01/GB. With OtterStorage, storage is the only thing billed: requests, deletes, ingress and egress are always free. Disk technology: only OtterStorage lets you choose HDD, SSD, or NVMe per bucket; the rest use access-frequency storage classes, with no choice of disk type.
