Installing an application can be as simple as opening the App Store and selecting Install.
That’s particularly useful for beginners who want to experiment with self-hosting without spending hours learning Docker Compose.
OpenMediaVault
OMV also has a web interface, but it exposes considerably more storage and system configuration.
That makes it more powerful, but also means there is more to learn.
You’ll encounter concepts such as:
- Physical disks
- File systems
- Mount points
- Shared folders
- Users
- Groups
- ACLs
- RAID
- Network interfaces
- Services
For someone building their first server, this can initially feel more complicated.
CasaOS vs OpenMediaVault for Storage
Winner: OpenMediaVault
If you’re primarily interested in building a NAS, OpenMediaVault is the stronger option.
OMV was specifically designed around network storage and provides extensive storage-management capabilities.
It supports multiple file systems and includes features such as RAID, quotas, ACLs, SMART monitoring, Btrfs snapshots, and storage-related scheduled tasks.
For example, you could build a server with:
Raspberry Pi / Mini PC
│
