The short version

  • Each has a real cost: Cloudflare R2 there is no archive tier below Infrequent Access, so genuinely cold data costs roughly ten to fifteen times what it would cost in a deep archive class and there is nowhere cheaper to lifecycle it to.; Storj billing includes a per segment charge and every object consumes at least one segment, so a bucket holding millions of small files can cost several times what the four dollar per terabyte headline implies.
  • They diverge on capability: Cloudflare R2 covers Zero egress billing, Storj covers Erasure coded distribution.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cloudflare R2

  • There is no archive tier below Infrequent Access, so genuinely cold data costs roughly ten to fifteen times what it would cost in a deep archive class and there is nowhere cheaper to lifecycle it to.
  • Class A operations are billed at 4.50 USD per million, so a workload that writes millions of small objects can spend more on operations than on the storage those objects occupy.
  • Infrequent Access carries both a retrieval fee and a thirty day minimum storage duration, so data that is deleted or re-read sooner ends up more expensive than if it had stayed on Standard.
  • You choose a location hint rather than a region, so you cannot prove to an auditor which datacentre holds an object unless you use a jurisdiction restricted bucket, and jurisdictions are limited.
  • Support level follows your Cloudflare account plan rather than the storage spend, so a team on a low tier account gets ticket support with no storage specific SLA, and an R2 incident is a Cloudflare incident you cannot fail over from because the free egress only exists inside Cloudflare.

Storj

  • Billing includes a per segment charge and every object consumes at least one segment, so a bucket holding millions of small files can cost several times what the four dollar per terabyte headline implies.
  • Reconstructing an object requires responses from dozens of independent nodes, so time to first byte is noticeably higher than a centralised bucket and it is a poor fit behind a latency sensitive read path.
  • Performance depends on the mix of node operators serving you at that moment rather than on a datacentre you can raise a ticket against, so slow reads are diagnosed statistically rather than fixed.
  • The hosted S3 gateway terminates encryption on Storj infrastructure, so using the convenient access path gives up the end to end encryption that is the main architectural argument for the service.
  • The S3 gateway is compatible rather than identical, so tools that lean on less common API calls, multipart edge cases or unusual header behaviour need testing before you commit a workload to it.

Answered from the vendors’ own pages

Cloudflare R2: Is egress really free, with no hidden transfer charge?

Yes for data served out of R2 to the internet. You still pay per operation for the requests that serve it, and if you pull data into R2 from another provider you pay that provider the egress on the way in.

Storj: Why is my bill higher than four dollars per terabyte?

Almost always the per segment fee. Objects are split into segments and small files each consume one, so a few million tiny objects generate a segment charge that dwarfs the storage line.

Cloudflare R2: How does the total cost compare with S3 for a public download bucket?

Storage is more expensive per terabyte than S3 Infrequent Access, but S3 charges roughly 90 USD per terabyte served. Any bucket that serves more than about a fifth of its stored volume each month is cheaper on R2.

Storj: Can node operators read my data?

No. Files are encrypted client side and each operator holds only an erasure coded fragment, which is not a readable portion of the file.

Cloudflare R2: Can I use R2 without using the rest of Cloudflare?

Yes, it works through the plain S3 API from anywhere. You lose the Worker binding and the free CDN caching in front of it, which is where a lot of the practical benefit sits.

Storj: Is there a minimum retention period?

No. You are billed for what you store while you store it, unlike several competitors that bill a ninety day minimum whatever you delete.

Cloudflare R2: Does R2 have a cold archive class like Glacier?

No. Infrequent Access is the coldest tier, at two thirds of the Standard rate plus retrieval fees.

Storj: Is it fast enough to serve a website from?

For large files with parallel reads, yes. For many small objects where time to first byte matters, put a CDN in front of it or use something centralised.
