Carbide Network vs Datum Storage

Carbide Network is a distributed storage service that links users’ files with independent providers. Its personal offering covers photos, documents and backups, with photo and video auto-sync, an encrypted vault, expiring share links and up to 10x redundancy. Files are encrypted on the user’s device with AES-256-GCM; the service describes its design as zero-knowledge. Encrypted chunks are spread among providers, and users choose between 1 and 10 copies. Users manage their private encryption keys, and Carbide says lost keys cannot be recovered. Business tools include role-based team workspaces, audit logs, retention policies and geographic redundancy across 30+ regions. Developers get API-first, S3-compatible storage, a versioned API and a Swift SDK. The service lists macOS, Windows, iOS and Android apps, as well as API access. Personal storage is billed at $0.002/GB. The network is provided without warranties, and performance depends on the combined behavior of independent participants.

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.
