- Four line items reliably cost more than the storage rate you were quoted - Egress is the obvious one: AWS charges USD 0.09/GB up to 10 TB, only the first 100 GB free - That AWS egress is 441 dollars of our 472.60 total - DigitalOcean charges 0.01/GB, Scaleway EUR 0.01 (about 0.0116), Storj 0.007/GB: better than AWS, not zero - On a 50 TB month that gap is real money - Only R2 and Tigris charge nothing with no ceiling attached - Wasabi and iDrive e2 also print a zero, but bound it with a fair-use multiple of what you store - The "egress cap" column is there so you can tell the two kinds of zero apart - Class A operations are the second: R2's 4.50 per million stings on list-loops or high write volume - AWS is 5.00 per million for the same class - Backblaze, DigitalOcean, Scaleway, Hetzner, Storj, Bunny and iDrive charge nothing per request at all - Backblaze went furthest, making Class A, B and C calls free, metering only outbound event callbacks - Minimum retention is the third, a storage price multiplier in disguise - Wasabi's 90 days means a seven-day object lifetime pays roughly thirteen times the headline rate - Minimum billable object size is the fourth: Wasabi bills every object at at least 4 KB - AWS applies a 128 KB floor on its infrequent-access classes, so the cheap tier costs more for thumbnails - Store ten million 1.5 KB objects behind a 4 KB floor and you pay for 40 GB where you stored 15
Hetzner Object StorageThe cheapest credible S3 endpoint in Europe, with a deliberately thin feature set.89.1
StorjDecentralised erasure-coded storage: USD 4/TB stored, USD 7/TB egress, no regions.87.9
Backblaze B2Cheap US and EU object storage with free egress up to three times stored volume.87.1
Bunny StorageEdge storage built as a CDN origin, with its own API rather than a faithful S3 one.82.4
MinIOThe self-hosted S3 reference implementation, your hardware, your bandwidth, your SLA.78.8
Scaleway Object StorageEuropean-sovereign S3 storage with multi-AZ classes and a real IAM system.77.3
DigitalOcean SpacesBundled object storage plus free CDN, priced as a flat base fee with overages.76.8
Cloudflare R2S3-compatible object storage with zero egress fees, on Cloudflare's network.73.6
WasabiFlat-rate hot storage with no egress or API fees, bounded by a fair-use cap.68.5
TigrisGlobally distributed S3-compatible storage that caches objects near readers.67.9
AWS S3The API everything else copies, and by far the most expensive egress in this roster.19.0Price is one group of 10 fields out of 28. Everything else, features, limits, portability, how well any of it works for agents, is on the full s3-compatible storage compared: true cost at 1 tb + 5 tb egress comparison.
0.007/GB: better than AWS, not zero and Tigris charge nothing with no ceiling attached and iDrive e2's 4.50 per million stings on list-loops or high write volume, Bunny and iDrive charge nothing per request at all's 90 days means a seven-day object lifetime pays roughly thirteen times the headline rate bills every object at at least 4 KB, Hetzner and Bunny have no IAM policy language at all; GetBucketVersioning and PutBucketVersioning are unimplemented fires into Cloudflare Queues, Backblaze uses its own payload, Scaleway, iDrive, Storj, MinIO and AWS (USD 4/TB), iDrive e2 and Tigris, the only two charging nothing per gigabyte with no ceiling-to-AWS gap will not be closed by any feature survive has versioning and notifications but we could not confirm object lock has notifications but no versioning and only a bucket-level retention lock: its free tier would take the total from 22.74 to 14.85, noted in the cell's no-egress model is bounded by a ~1x fair-use cap, outside this scenario has no price because you buy servers and transit, not storage bills storage and operations only charges no egress fee, but its AUP limits monthly downloads to roughly the volume you store reviews or restricts the account rather than sending a larger bill, so there is no list price's is 90 days, so a file written and deleted on day two costs 90 days of storage's community build lost its admin console in 2025, so the free tier is less complete than it was
