The short version

Only Storj has a free tier, so it costs nothing to try first.
Each has a real cost: 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.; Sync.com all Teams plans require a minimum of 3 users

Where each one falls short

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

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

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.

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.

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.

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

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.

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

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.
