Storj vs Synology C2 (2026): which should you pick?

Pick Storj if

• Fits if you're a developer who wants S3 storage and is fine with a trial first
• Works for teams that store a lot and read it back rarely

Look elsewhere if

• Skip it if you want a drive that syncs, as this is object storage
• Watch out: a $5 monthly minimum applies after the trial and is a floor, not a credit
• Pricey if you read data often: egress is another $7 per TB
• Watch out: Standard bills a 30-day minimum retention, and Object Mount licenses are $29 or $39 a month

Pick Synology C2 if

• Fits if you own a Synology NAS and want an offsite copy
• Works for teams that want S3 object storage at a flat per-terabyte rate

Look elsewhere if

• Not for you if you want a consumer file sync app, because C2 is built around Synology NAS and S3 workloads
• Skip it if you don't own Synology hardware or an S3 tool to connect
• Watch out: prices exclude VAT, which is added at checkout
• Tight if you want deduplication or custom rotation, which need the Advanced plan of C2 Storage for Hyper Backup
• Watch out: OneStorage pricing is shown only by a capacity calculator

Storj

• A $5 monthly minimum fee applies after the trial; it is a floor, not a usage credit, and USDC payers are exempt.
• Standard bills a 30-day minimum retention and rounds objects under 50 KB up to 50 KB.
• Paid Object Mount licenses are $29 per license per month (500 GB of Storj storage included) or $39 for use with other S3 storage.
• Standard and Advanced are bought through sales contact on the pricing page.

Synology C2

• C2 Storage is designed for Synology NAS; it is not a general-purpose consumer file sync app.
• The OneStorage price is shown only by a capacity calculator, so no figure was readable; $7.99 per TB is the Object Storage rate on its page.
• Prices exclude VAT, which is added at checkout by billing address.
• Deduplication and custom rotation need the Advanced plan of C2 Storage for Hyper Backup.
