Storj vs Amazon S3

SEPT 2026 audit

A comparison of Storj and Amazon S3 built from values read directly from each provider's own documentation, with the source recorded against every figure.

Reviewed by Palash BagchiUpdated 21 criteria comparedSources last checked

The short answer

Choose Storj if…

Workloads that want data spread across many independent locations rather than one provider's region, at a storage rate close to the cheapest here.

Editorial · Palash Bagchi · approved

Choose Amazon S3 if…

Workloads already inside AWS, where keeping data in the same region as the compute avoids the transfer charges that dominate an object storage bill.

Editorial · Palash Bagchi · approved

Consider something else if…

  • Storj: Egress is charged at the same $7 per TB as storage, so a read-heavy workload costs roughly double what the storage line suggests — the three free-egress providers here charge nothing for it.
  • Amazon S3: Egress is the cost that decides this category and S3 charges for it, where R2, Wasabi and Tigris do not. Prices also vary by region, so a figure quoted anywhere is only true for the region it was read in.

Documented by only one.

These criteria are published by one provider and not the other. An absence here means we have not found a source, not that the feature is missing — except where we say we read the other provider's own page on a given date and it does not state it. Those rows lean, and the provider can correct them with a link.

Free tierAmazon S3: Yes
Credit card to startStorj: No
Pricing modelAmazon S3: Per region and per storage class, with storage, requests, retrievals, data transfer and management features each metered separately. AWS states there is no minimum charge, and bills storage in binary gigabytes — 1 GB is 2^30 bytes, not 10^9.
Storage (entry plan)Amazon S3: None. S3 has no plans and no included storage — AWS states there is no minimum charge and you pay only for what you use, billed per GB-month from the first byte. New accounts get AWS Free Tier credits ($100 immediately, up to $200 over six months) which are spendable credit rather than a standing storage allowance.
RegionsStorj: Distributed across tens of thousands of storage locations globally rather than named regions; a US-only option runs on SOC 2 type 2 compliant data centres.
Uptime SLAAmazon S3: 99.9% for S3 Standard, Express One Zone and the Glacier retrieval classes; 99.0% for Intelligent-Tiering, Standard-Infrequent Access, One Zone-IA and Glacier Instant Retrieval.
Minimum storage durationAmazon S3: None on S3 Standard. 30 days on Standard-IA and One Zone-IA, 90 days on Glacier Instant and Flexible Retrieval, 180 days on Glacier Deep Archive, each with a pro-rated charge for early deletion.
Support on entry paid planStorj: Support hours are 9am to 8pm Eastern on business days for Severity Level 1 errors, and 9am to 5pm Eastern for everything else. Committed in the terms of service rather than sold as a tier.
Response time commitmentStorj: For a Severity Level 1 error: acknowledgement within one business day, updates every eight hours, and resolution no later than three days. No uptime percentage is published anywhere in the terms.
ISO 27001Amazon S3: Covered under AWS's account-wide ISO/IEC 27001:2022 certification — not scoped per-service the way SOC, HIPAA and PCI DSS are on AWS's own site.Storj: not stated on its own page when read on 2026-09-21 — corrections welcome · every such claim about Storj.

Egress over allowance: Storj or Amazon S3?

Storj: $7 per TB, the same rate as storage — reduced from $20 per TB on the Standard tier. Storj charges for egress where R2, Wasabi and Tigris do not, but at a tenth of what S3 charges.

Amazon S3: $0.09 per GB for the first 10 TB a month out to the internet, after a free 100 GB aggregated globally. It falls to $0.085 above 10 TB, $0.07 above 50 TB and $0.05 above 150 TB. This is AWS's outbound data transfer rate rather than an S3-specific one — the charge that R2, Wasabi and Tigris do not levy at all.

Should I choose Storj or Amazon S3?

Pick Storj if Workloads that want data spread across many independent locations rather than one provider's region, at a storage rate close to the cheapest here.

Pick Amazon S3 if Workloads already inside AWS, where keeping data in the same region as the compute avoids the transfer charges that dominate an object storage bill.
