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.

Sync.com

  • All Teams plans require a minimum of 3 users
  • The advertised low monthly rate (e.g. $4/month for Teams 1TB) is a promotional annual rate described as 50% off; the standard monthly price is $8/month without the promotion
  • Enterprise pricing for 100+ users is custom and requires contacting a dedicated account manager

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.

Sync.com: What are the Sync.com team plan price differences?

Sync.com offers three main team tiers: Teams 1TB at $8/month per user (annual), Teams 2TB at $12/month per user (annual), and Teams 10TB at $18/month per user (annual). All require a minimum of 3 users. Higher tiers include enhanced features like custom branding, admin delegation, and longer file history.

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.

Sync.com: Does Sync.com offer a free trial?

Yes, Sync.com offers a 30-day free trial with no credit card required. All plans also include a full 30-day money-back guarantee.

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.

Sync.com: What file history retention does Sync.com provide?

Sync.com Teams 1TB includes 180-day file history. Teams 2TB and Teams 10TB offer 365-day history. This history duration applies across all shared files and team folders.

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.
