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.; TrueNAS requires self-hosting on x86 hardware, no managed cloud offering; organisations must provision, configure, and maintain their own infrastructure

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.

TrueNAS

  • Requires self-hosting on x86 hardware, no managed cloud offering; organisations must provision, configure, and maintain their own infrastructure
  • ZFS filesystem entails high memory requirements (1 GB RAM per 1 TB of storage recommended), increasing costs for large deployments
  • Limited ARM/embedded support; Community Edition is primarily x86-64, reducing deployment options for edge installations
  • Clustering and replication setup requires operational expertise; misconfiguration can lead to data loss
  • Enterprise support and SLA guarantees require paid subscriptions; Community Edition relies on peer-based forums

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.

TrueNAS: What is the cost of TrueNAS Community Edition?

TrueNAS Community Edition is free and open-source. There are no licensing fees, but organisations must purchase and maintain their own x86 hardware. Enterprise Edition requires paid support contracts for production environments.

Source
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.

TrueNAS: Can I replicate TrueNAS data between sites?

Yes. TrueNAS supports snapshot-based replication over network links, enabling disaster recovery and business continuity. Replication can occur between Community Edition systems or between Enterprise Appliances.

Source
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.

TrueNAS: What storage protocols does TrueNAS support?

TrueNAS simultaneously supports NFS (network file system), SMB (Windows file sharing), iSCSI (block storage), and S3-compatible object storage, all from the same storage pool.

Source
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.
