Datum Storage vs Stratos

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.

Stratos is a distributed infrastructure network offering computation, storage, and network traffic resources for blockchain applications. Its four core modules are blockchain, decentralized storage, decentralized databases, and decentralized computing. The documentation describes it as a platform for blockchain and Dapp developers to deploy, store, and execute code and data. The network uses Proof-of-Stake for its value layer, Proof-of-Traffic for resources, and Proof-of-Authority for meta-services; Proof-of-Traffic rewards participants based on network traffic contributions. Stratos IPFS, or SPFS, is an IPFS cluster for persistent storage. Its guide covers uploading, fetching, pinning, unpinning, and sharing files through API and WebUI instructions. The private access token is free with usage limits that can be expanded through a subscription. Gateway requests require an access token and face tier-based rate and traffic limits. Stratos lists Android, iOS, Linux, macOS, web, Windows, API, and self-hosted access, and is headquartered in Canada.
