Object storage, compared honestly.

28 providers: price per TB, egress semantics, free tiers, hidden minimums, S3 compatibility, encryption model, and the column almost nobody can fill in: whether the provider cryptographically proves it still has your data. Every fact links to a source fetched on the date shown. Machine readers: the full dataset is at /compare/providers.json.

* "$0 egress" means three different things across providers: unconditional, an allowance tied to stored volume, or fair-use with suspension rights. Per-provider conditions are in the detail sections below. Prices are headline US rates; EUR-native prices are converted at the ECB reference rate and flagged in the source notes. Arweave sells permanent pay-once storage and does not fit monthly pricing.

Details and sources

Arweave

Websitehttps://arweave.org
Categorydecentralized
Free tierNo free tier at protocol level. (Some bundlers waive fees for tiny uploads; not verified on this fetch.)
MinimumsNo minimums; pay per upload. The inverse gotcha applies: storage is PERMANENT - there is no delete, no retention control, and uploaded data is public.
S3 compatibilityno. Not an S3 system and not rent-based - one-time payment for permanent storage, so $/TB-month is null by construction. Protocol base fee on 2026-07-18: 11,025,429,884,381 winston/GiB = ~11.0254 AR/GiB (linearity cross-checked at 1 MiB = 10,799,950,108 winston). At AR = $1.91 (CoinGecko, same day) that is ~$21.06/GiB one-time, ~$19,600/TB (decimal) one-time - DERIVED from two volatile inputs. Retail via the ArDrive Turbo bundler (card payments): $32.56/GiB one-time (~$30,300/TB) per Turbo's own rates API - Turbo's fiat rate embeds a ~55% premium over protocol-fee-times-spot at today's prices.
EncryptionNone - data on Arweave is public and permanent by design. Confidentiality requires client-side encryption before upload, and 'permanent ciphertext' carries its own risk profile (no rotation, no deletion, harvest-now-decrypt-later).
VerificationStrongest in this tranche: miners must prove cryptographic access to random historical chunks of the weave (Succinct Proofs of Random Access) to mine blocks; proofs are publicly verifiable on-chain, and anyone can independently retrieve and hash their data via any gateway. Caveat: no per-customer contract or fixed replica count - persistence is a probabilistic, incentive-driven property of the whole network plus its endowment, not an SLA.
RedundancyData replicated by independent miners worldwide; replica count is incentive-driven and variable, not contractual. Long-term persistence rests on the storage endowment model (upfront fee funds ~200 years of storage under assumed cost declines) - an economic design assumption, not a guarantee.
Tooling verifiednot verified
Payment methodsAR token at protocol level, fiat (card) via bundler services such as ArDrive Turbo, which convert to credits
Launchedmainnet June 2018
NotesWrong tool for bulk backup: at ~$19,600-30,300/TB one-time (today's derived figures) it is 3-4 orders of magnitude above the monthly-rent providers here even amortized over decades, and data cannot be deleted. Its niche is small, high-value, permanently-public artifacts (proofs, archives, metadata). Both USD figures move with AR price and network fee; the AR-denominated fee itself has risen sharply as AR's USD price fell. Egress: no protocol-level charge; retrieval is via public gateways (fair-use, availability varies) or your own node - hence null rather than 0.

Categoryhyperscaler
Storage price$23 per TB-month
Egress$90 per TB
Free tierNo permanent free S3 storage tier. New customers: $200 AWS credits. 100 GB/month data transfer out to internet free, aggregated across all AWS services/regions (except China/GovCloud).
MinimumsNo minimum storage duration or minimum charge for S3 Standard (unlike IA/Glacier classes).
S3 compatibilityyes. The reference implementation. US East (N. Virginia): Standard storage $0.023/GB-mo first 50 TB, $0.022 next 450 TB, $0.021 over 500 TB. PUT/COPY/POST/LIST $0.005/1,000 requests; GET $0.0004/1,000. Prices vary by region (some regions materially higher). $23/TB figure uses decimal conversion of the first-50TB rate.
EncryptionServer-side encryption default (SSE-S3, AES-256, since Jan 2023); SSE-KMS, SSE-C, and client-side encryption optional.
VerificationNo customer-facing possession proofs. Integrity via ETag/Content-MD5 and optional additional checksums (SHA-256/CRC family) computed on upload. 11-nines durability is an internal claim backed by AWS engineering, not externally auditable.
RedundancyObjects stored redundantly across >=3 Availability Zones in-region; 11-nines durability design claim.

NotesEgress tiered: $0.09/GB first 10 TB/mo, $0.085 next 40 TB, $0.07 next 100 TB, $0.05 over 150 TB (after the 100 GB/mo free allowance). Headline $90/TB is the first-tier rate. Request and management fees add materially for small-object workloads. Numbers taken from AWS's own pricing data feed (b0.p.awsstatic.com) because the pricing page tables are JS-rendered. Unit caveat: AWS bills storage in binary units (1 GB = 2^30 bytes, 1 TB = 1024 GB), so an actual binary TB-month costs about 2.4 percent more than the decimal per-TB figure shown here. The decimal convention is used for every provider in this table so the column stays comparable.

Egress$90 per TB
Free tierNo free tier for Glacier storage classes. New AWS customers get up to $200 in Free Tier credits (free plan available 6 months after account creation; credits expire 12 months after creation).
Minimums180-day minimum storage duration, the longest in this table (early delete charged pro-rata for the remaining days). Each archived object also carries 40 KB of extra metadata: 32 KB billed at the Deep Archive rate plus 8 KB billed at the S3 Standard rate. At $0.00099/GB-mo the per-object overhead can exceed the cost of the data itself for small files.
S3 compatibilitypartial. Same S3 API and bucket, but objects are archived and not readable in place: you must call RestoreObject and wait up to 12 hours. US East (N. Virginia): storage $0.00099/GB-mo; standard retrieval $0.02/GB plus $0.10 per 1,000 requests; bulk retrieval $0.0025/GB plus $0.025 per 1,000 requests; PUT/COPY/POST/LIST $0.05 per 1,000; GET $0.0004 per 1,000; lifecycle transition in $0.05 per 1,000. $0.99/TB uses decimal conversion.
EncryptionServer-side encryption default (SSE-S3, AES-256); SSE-KMS, SSE-C, and client-side encryption optional. AWS holds the keys unless you supply your own.

NotesThe cheapest storage rate in this table by a wide margin, and the most expensive assumptions attached to it. Holding a terabyte costs about $0.99/month; getting that terabyte back costs roughly $20 in standard retrieval fees plus internet egress from $0.09/GB, and takes up to 12 hours. Bulk retrieval cuts the retrieval fee to about $2.50/TB if you can wait. Right answer for archives you genuinely expect never to read; wrong answer for anything you might need in a hurry. Restore double-billing: while a restored copy exists you pay for BOTH the archived object at its archive rate AND the temporary restored copy at S3 Standard rates, for however long you keep it available. Unit caveat: AWS bills storage in binary units (1 GB = 2^30 bytes, 1 TB = 1024 GB), so an actual binary TB-month costs about 2.4 percent more than the decimal per-TB figure shown here.

NotesThe classic Glacier archive tier. Retrieval runs from about 1 minute (expedited, $30/TB plus request fees) to 12 hours (bulk, free), with standard around $10/TB, and restore is a separate step before any read. Full recovery cost is retrieval plus internet egress from $0.09/GB, so budget the exit, not just the storage. The 40 KB per-object metadata overhead makes many-small-file archives cost well above their raw byte total. Restore double-billing: while a restored copy exists you pay for BOTH the archived object at its archive rate AND the temporary restored copy at S3 Standard rates, for however long you keep it available. Unit caveat: AWS bills storage in binary units (1 GB = 2^30 bytes, 1 TB = 1024 GB), so an actual binary TB-month costs about 2.4 percent more than the decimal per-TB figure shown here.

NotesCheapest Glacier tier that still behaves like normal S3 (no restore wait). Watch the stacking cost of getting data back: $0.03/GB retrieval PLUS standard internet egress from $0.09/GB. Pulling a full terabyte back to your own machine is roughly $30 retrieval plus $90 egress on top of storage, so the archive is cheap to hold and expensive to leave. The 128 KB minimum billable object size punishes archives of many small files. Unit caveat: AWS bills storage in binary units (1 GB = 2^30 bytes, 1 TB = 1024 GB), so an actual binary TB-month costs about 2.4 percent more than the decimal per-TB figure shown here.

S3 compatibilityno. Not an object store: per-repository hosting for BorgBackup and Restic repositories (SSH/borg protocol and Restic endpoints). No S3 API. Headline $/TB-mo is DERIVED from plan math, not a posted unit price: Medium = $90/yr / 1 TB = $7.50/TB-mo (Small ~$8.00, Large ~$6.88). Overage beyond included storage: $0.01/GB-mo (Small), $7/TB-mo (Medium), $6/TB-mo (Large).
EncryptionClient-side end-to-end encryption via borg/restic when the user enables it (the standard mode; keys never leave the client). BorgBase additionally offers append-only repo mode and 2FA. Encryption is client-tool-enforced, not provider-enforced - an unencrypted repo is possible if the user creates one.
VerificationNo provider-run possession proofs - but the customer can genuinely self-verify: 'borg check --verify-data' and 'restic check --read-data' read every block back from the server and verify cryptographic checksums client-side. Strongest customer-side verification path among the centralized providers in this tranche, at the cost of egress time (free) and compute.

EncryptionClient-side / E2E by design. Bring your own encryption (age, gpg, or an existing E2EE layer) through a passthrough gateway that never holds your keys, or use the TypeScript SDK's AES-256-GCM. The coordinator is architecturally incapable of reading customer plaintext.
VerificationCryptographic possession proofs, payment-gated: stored objects are challenged with chunk-level merkle proofs on a continuous cycle, targeting roughly every 4 hours, and providers earn only for proofs they pass. Proofs do fail and the pass rate varies by node, which is why replication is 3x and payment is per passed proof. Not publicly verifiable on-chain: proofs are issued and recorded by Obsideo's own coordinator, unlike Arweave and Sia, which settle proofs on a public chain that anyone can audit.
Redundancy3 full replicas per object on distinct provider nodes (RF=3, network-wide default); hybrid datacenter hot tier plus distributed tier. Placement prefers separate failure domains, but operator and facility independence is not guaranteed: some nodes currently share a datacenter.

MinimumsNo fixed minimums, but renters must lock siacoin into file contracts up front (contract funding + host collateral mechanics); contracts run for a period (typically weeks) and renew.
S3 compatibilitypartial. No hosted S3 endpoint from the network itself. renterd (the reference renter) ships an S3-compatible gateway you run yourself; boto3/aws_cli/rclone work against it. rclone also has a legacy native 'sia' backend (siad). Prices are market medians from SiaScan on 2026-07-18: storage 1,831 SC/TB-month, download 2,000 SC/TB, converted at SC = $0.0006007 (CoinGecko same day) => ~$1.10/TB-mo raw storage, ~$1.20/TB egress. DERIVED VALUES -- see status_notes.
EncryptionClient-side end-to-end encryption always: renterd encrypts and erasure-codes locally before upload; hosts see only ciphertext shards.
VerificationStrongest in this tranche: hosts must submit Merkle-proof storage proofs to the Sia blockchain to be paid at contract end; missing proofs forfeits payment and burns host collateral. Publicly verifiable on-chain. renterd additionally health-checks and migrates shards. Caveat: proofs cover contracted sectors at proof windows, not continuous per-object attestation to the end user.
RedundancyRenter-controlled erasure coding across independent hosts; renterd default historically 10-of-30 (3x expansion), user-tunable. Durability depends on renter maintenance (renewals, repair) staying online or being delegated.

Effective cost per usable TB is roughly 3x the raw host price under default 10-of-30 redundancy (~$3.30/TB-mo at today's numbers) plus contract fees -- comparisons using the raw $1.10 flatter the network. Network scale is small vs the rest of this tranche: SiaScan showed 2.12 PB used of 8.56 PB capacity. Active-host count on SiaScan rendered ambiguously (display artifact) and was not recorded.

EncryptionClient-side end-to-end, user-held keys: 'Tarsnap encrypts all data before it leaves a computer'; the key file holds the only decryption keys. Lost key = unrecoverable data.
VerificationCryptographic integrity on the client (archives verified via the client's crypto on restore). No possession proofs while stored; at-rest durability is delegated to Amazon S3 (Tarsnap stores ciphertext on S3 Standard).
RedundancyInherits Amazon S3 Standard redundancy (Tarsnap FAQ states data is stored on S3, original version, not reduced-redundancy).

NotesNominal per-TB price is ~30x the commodity providers here; it is priced for small, high-value, deduplicated backups, not bulk storage. Single-operator service (Colin Percival) -- bus-factor consideration. Unix-like clients only.

NotesEgress free by policy and broad: 'we don't charge for regional data transfer, region-to-region data transfer, or data transfer out to the internet' - no allowance ratio stated on the pricing page (ToS not fetched, so any fair-use backstop is unverified). Young company relative to the rest of this tranche; treat longevity accordingly.

NotesFree egress is a fair-use policy, not unconditional: free only while monthly egress <= active storage volume; Wasabi 'reserves the right to limit or suspend' service for sustained excess (no metered overage billing -- enforcement is service action). Not suitable as a high-egress CDN origin.
