Datum Storage vs Storj

Datum Storage is decentralized cloud storage running on the Datum Network, with access listed for Android, iOS, and API use. Datum Drive adds a virtual hard disk to a computer that behaves like a folder. The product says files are end-to-end encrypted and that users hold the key. Storage accounts attach to a Datum Identity, whose creation requires email and phone verification. For software connections, the service supports the Amazon S3 API format and custom S3 endpoints. After account creation, users receive a URL plus a key and secret corresponding to S3 access credentials; Datum recommends Signature Version 4 if a backup application offers a choice. Arq Backup for Mac and Windows is listed as tested. Duplicati, Duplicity, and Duplicacy are named as S3-compatible applications but have not been tested by Datum. The Datum ID app is listed in the App Store and Google Play for sign-up and credential and usage management, though the mobile workflow is described as coming soon. A free plan provides one terabyte for the first year. Additional storage is listed at US$3.99 per terabyte per month and is also described as coming soon.

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.
