Sia vs Storj

Sia offers encrypted, decentralized cloud storage through a consumer app and tools for developers building storage into applications. Files are encrypted on the user’s device before upload, and Sia says nobody else can read them. The app describes files as redundantly held across independent hosts worldwide, with parallel downloads from multiple hosts. Sia describes its peer-to-peer network as having no central access point or single point of failure. Consumer plans list 50 GB on Free, 500 GB for $7.99 a month on Plus, 5 TB for $14.99 a month on Pro, and 10 TB for $19.99 a month on Unlimited; Unlimited lists 4.99 USD/TB-mo over its included capacity. Separately, the network page lists median prices of $3.53/TB/month for storage at 3X redundancy, $0.03/TB for upload, and $2.25/TB for download. Developers can use storage SDKs for Rust, Go, Python, and JavaScript, or the S3-compatible s3d gateway with rclone, Cyberduck, Nextcloud, and Duplicati. The SDK can connect to an indexer hosted by the user.

Storj provides distributed cloud Object Storage and Object Mount for accessing cloud files as if they were local. Object Storage is described as a drop-in AWS S3 replacement, while Object Mount works with S3-compatible storage and provides POSIX access without modifying files or requiring a gateway. Existing buckets can be mounted without migration. Storj encrypts data and metadata end-to-end, at rest, and in transit by default. Objects are split across tens of thousands of storage nodes, with tiers designed for 11 nines of durability. S3-compatible object lock and versioning support immutability and protection from accidental deletion. Listed integrations include Amove, Veeam, TrueNAS, Splunk, LucidLink, FileZilla, and Cyberduck. Customers use it for backup and recovery, media workflows, AI, and scientific work. Standard pricing is $7 a month per TB for storage, with 7.00 USD per TB egress and a 5.00 USD minimum monthly fee. A 30-day free trial is available; there is no free plan.
