ObjectiveFS vs PowerScale OneFS

ObjectiveFS is a shared distributed POSIX file system for persistent storage across cloud instances, laptops, containers, and office servers. It runs on Linux and macOS and can be self-hosted. The software runs on customer machines and connects directly to object stores through the S3 API, without storage clusters or metadata servers. Multiple machines can read and write the same filesystem, with updates visible across them. Supported targets include Amazon S3, Google Cloud Storage, Azure Blob Storage, IBM Cloud Object Storage, Oracle Cloud, DigitalOcean Spaces, Scaleway, Wasabi, Ceph, MinIO, NetApp StorageGRID, Hitachi Content Platform, and S3-compatible stores. Data is encrypted locally with a customer-known key and remains encrypted in transit and at rest; checksums verify integrity. Automatic and checkpoint snapshots can be mounted read-only. Personal costs $99 a month and includes 3 instances, up to 50 instances, 5TB storage, and unlimited filesystems. A 14-day trial is available, but there is no free plan. Object-store charges are billed separately. ObjectiveFS does not run natively on Windows, though a Linux machine can export it through NFS or Samba.
