Spec score 9.2 #2 of 25 in Decentralized Storage Services

What it is

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.
