What are Ceph and Spacedrive?
Ceph
Ceph is a highly scalable distributed storage system that provides object, block, and file storage in a unified cluster. It is designed for fault tolerance with no single point of failure.
- Unified object, block, and file storage
- Self-healing and self-managing
- Massive scalability
Spacedrive
Spacedrive is an open-source, cross-platform file manager written in Rust, built around a virtual distributed filesystem (VDFS). It indexes and organizes files across multiple devices and storage locations from a single native app.
- Virtual distributed filesystem
- Indexes files across devices
- Cross-platform native app
