I once watched a founder open his AWS bill and go quiet for a full ten seconds. Not angry quiet. The kind of quiet where someone is doing math in their head and not liking the answer. His startup had eight terabytes of user uploaded video sitting in S3 Standard, and between storage, egress, and a spike in downloads that month, the invoice had nearly tripled. He asked me the question I now get asked constantly. Is there something cheaper that still works like S3?
The honest answer is yes, and also, it depends what you mean by works. Decentralized storage networks like Filecoin, Arweave, and Storj have gotten genuinely production ready in 2026. But they are not drop in replacements in the way marketing pages suggest. Each one trades something for that lower price tag. Your job is figuring out which tradeoff you can actually live with.
What You’re Really Comparing
AWS S3 is one company renting you space on its own hardware, replicated across its own data centers, backed by its own SLA. You pay a premium for that single point of accountability.
Decentralized storage flips the model. Your data gets split, encrypted, and spread across independent operators who never see the whole file. Nobody can hand it over on a subpoena because nobody has all of it. That’s the pitch. The cost is complexity, and sometimes, unpredictable retrieval speed.
So this isn’t really “cheap storage vs expensive storage.” It’s centralized accountability vs distributed resilience, and the price gap is just the visible symptom of that deeper choice.
Cost Per TB Compared: AWS S3 vs Filecoin vs Storj vs Arweave
Here’s where the numbers actually sit right now.
| Provider | Storage Cost | Egress / Retrieval | Payment Model |
|---|---|---|---|
| AWS S3 Standard | $0.023 per GB per month, about $23.55 per TB per month | $0.09 per GB after the first 100 GB free each month | Pay as you go, billed monthly |
| Filecoin (raw deal market) | Historically as low as $0.19 per TB per month, though real world deals vary a lot by provider | Often high due to gas and retrieval deal costs | Per deal, negotiated with storage providers |
| Filecoin Fil One (S3 layer) | $4.99 per TB per month with an 11 nines durability target | No egress or API request charges | Flat monthly, S3 compatible endpoint |
| Storj (Standard tier) | $7 per TB per month as of the simplified pricing that took effect July 1, 2026 | $7 per TB downloaded | Pay as you go, billed monthly |
| Arweave | One time payment, roughly $16,000 for 1 TB stored forever, based on the network’s historical cost curve | Low or included on most gateways | Single upfront payment, no renewals |
A few things jump out. Filecoin’s raw deal market is still the cheapest way to store bulk data by a wide margin, but you’re negotiating with individual storage providers the way you’d haggle over a shipping container, not clicking a pricing tier. Fil One exists specifically to remove that friction and give you an S3 shaped door into Filecoin’s cheaper backend, and it undercuts AWS by roughly 4 to 1 on storage with zero egress fees on top.
Storj actually raised prices in 2026, moving from its long standing $4 per TB to $7 per TB on the new Standard tier. It’s still meaningfully cheaper than S3, but the gap has narrowed, and that’s worth knowing before you assume decentralized always means dirt cheap.
Arweave doesn’t fit the monthly comparison at all, and that’s the point. You’re not renting space. You’re buying permanence.
Uptime and Redundancy: How Each Network Actually Stays Online
AWS gets its durability by replicating your object across multiple Availability Zones inside its own network. One company, many buildings, one throat to choke if something breaks.
Decentralized networks get there differently, and the mechanics matter more than people assume:
- Storj splits every file into pieces using erasure coding and scatters them across independent, globally distributed storage nodes. You only need a subset of those pieces back to reconstruct the full file, so losing several nodes at once still doesn’t cost you the data.
- Filecoin relies on cryptographic proofs, specifically Proof of Replication and Proof of Spacetime, where storage providers have to continuously prove they’re still holding your data or lose their staked collateral. Redundancy isn’t automatic though. You choose how many providers replicate your file, and that choice directly affects both cost and safety.
- Arweave requires miners to periodically produce a randomly selected block from the network’s entire history to be allowed to mine at all. That mechanism, called Proof of Access, makes forgetting old data economically irrational, since a miner who can’t recall history can’t earn new tokens.
- Fil One wraps Filecoin’s proof system in an S3 compatible layer and advertises durability checks running roughly every 24 hours, closing the gap between “cryptographically provable” and “actually verified on a schedule.”
None of these are worse than S3’s model on paper. They’re distributed instead of centralized, which buys resilience against one company going down or one region losing power. What you give up is a single number to call when something breaks.
Data Persistence Guarantees: Why “Permanent” Means Different Things
This is where a lot of comparisons get sloppy, so let’s be precise about it.
AWS S3 gives you durability, not permanence. Amazon commits to keeping your object intact as long as you keep paying and haven’t deleted it. Stop paying, and eventually it’s gone.
Filecoin storage deals work on a similar renewable logic. You pay for a set duration, the provider is contractually and cryptographically obligated to hold it for that period, and then the deal either renews or expires. It’s decentralized, but it’s still a subscription underneath.
Take time to read: what is DePIN crypto
Permanent storage on Arweave is a different economic animal. You pay once, and the fee splits between an immediate payment to the miner and a much larger deposit into a storage endowment. That endowment earns yield over time, on the bet that hardware costs keep falling, theoretically funding your storage centuries into the future without another payment. It’s a clever wager on Kryder’s Law, the long observed trend that storage gets cheaper every year. Whether it holds up over a century is unprovable today, but the incentive design is real, and it’s the closest thing crypto has to an actual permanence guarantee.
Storj sits closer to Filecoin and S3 here. It’s a recurring, renewable service, not a one time forever payment.
IPFS vs S3: Clearing Up a Common Mix Up
People searching “ipfs vs s3” are almost always comparing the wrong things, so let’s fix that here.
IPFS is not a storage network. It’s a content addressing protocol, a way of naming and finding files based on what’s inside them rather than where they live. IPFS itself makes zero promises that your data will still exist tomorrow. If nobody is pinning your file, it can simply vanish off the network.
That’s exactly the gap Filecoin was built to close. Filecoin pays storage providers to keep pinning IPFS content over a guaranteed contract period, turning “maybe someone’s keeping this” into an economically enforced commitment. So the real comparison isn’t IPFS vs S3 at all. It’s Filecoin (IPFS plus paid persistence) vs S3, and once you frame it that way, the earlier cost and durability numbers actually apply.
Decentralized Storage Pricing Per TB: The Fine Print
Sticker prices rarely tell the whole story, and decentralized storage pricing has its own set of gotchas worth knowing before you commit a production workload:
- Minimum monthly fees apply even to tiny accounts. Storj has a baseline minimum, and Fil One charges $4.99 a month regardless of how little you store.
- Small object overhead adds up. Storj rounds objects under 50KB up to that minimum for billing, so a bucket of tiny files can cost more than the raw byte count suggests.
- Raw Filecoin deals often carry retrieval friction flat pricing doesn’t capture, since you’re pulling data back through gas fees and provider specific retrieval markets, not a simple API call.
- Arweave’s one time fee moves with the AR token price, so “permanent” storage isn’t a fixed dollar cost. Pay when AR is cheap and you win. Pay during a spike and you overpay for something you can never renegotiate.
Cheapest Cloud Storage for Backups: What Actually Works
If backups are the goal, not everything above applies equally, because backups have a specific access pattern. You write once, you read rarely, and when you do need to read, you often need it fast.
That changes the calculus:
- For cold, rarely touched backups, Filecoin’s raw deal market or Storj’s Active Archive style pricing usually wins on pure cost per TB, as long as you can tolerate slower retrieval.
- For backups you might need back quickly, Fil One or Storj’s Standard tier make more sense, since both are S3 API compatible and slot straight into existing backup tools like restic, rclone, or Duplicati without rewriting anything.
- For records that must never disappear, like compliance archives, legal documents, or anything with a multi decade retention requirement, Arweave’s one time payment model removes the risk of a forgotten renewal deleting something important years down the line.
- AWS S3 Glacier Deep Archive is still worth mentioning here too, since at roughly $0.00099 per GB it undercuts most decentralized options on raw cold storage cost, just without the censorship resistance or multi provider redundancy.
When AWS S3 Still Makes Sense
I’m not going to pretend decentralized storage wins every scenario, because it doesn’t. AWS S3 is still the better call when:
- You need consistent, low latency reads at scale for an application serving live traffic
- Your team needs a single vendor SLA and a support line to call at 3am
- You’re already deep in the AWS ecosystem and the integration cost of switching outweighs the storage savings
- Your workload needs tight IAM level access control and audit logging that decentralized networks don’t yet match
Final Take
Decentralized cloud storage isn’t chasing AWS on convenience, and it probably never fully will. What it’s chasing is something AWS structurally can’t offer: no single company holding your data hostage to a price hike, a policy change, or a regional shutdown. Filecoin and Fil One make the most sense if you want S3 like usability at a fraction of the price. Storj is the safe middle ground for teams that want decentralization without giving up a familiar API. Arweave is for the narrow but real category of data that genuinely needs to outlive you. Pick based on your access pattern, not the marketing page.
FAQ
Is decentralized cloud storage actually cheaper than AWS S3? For raw storage, yes, often by a wide margin. Fil One runs about $4.99 per TB monthly against S3’s roughly $23.55, and Storj sits around $7 per TB. Egress is where savings really show up, since AWS charges per GB downloaded while several decentralized options charge little or nothing.
What is the cheapest decentralized storage for backups? Raw Filecoin storage deals tend to be cheapest by cost per TB, with Storj’s archive tier close behind. The tradeoff is slower, more variable retrieval versus a flat rate S3 compatible service like Fil One.
How much does permanent storage on Arweave actually cost? It’s a one time payment, not a subscription, and it scales with data size and the current AR token price. As a rough benchmark, storing 1 TB permanently has landed around $16,000 upfront, roughly $60 to $70 a month spread across two decades, with nothing more to pay after that.
Is IPFS the same thing as decentralized storage? No. IPFS only handles content addressing and transfer, not guaranteed persistence. Filecoin pays providers to keep IPFS content pinned under contract, which is what actually makes it reliably retrievable.
Can I use Filecoin or Storj with my existing S3 backup tools? Yes. Both expose S3 compatible APIs, so tools like rclone, restic, and most backup software that already speak to S3 can point at them by changing the endpoint URL, usually without touching application code.
