TrueNAS vs OpenMediaVault
TrueNAS vs OpenMediaVault: ZFS, hardware requirements, ease of use and which NAS OS fits your build.
TrueNAS is the ZFS powerhouse; OpenMediaVault is the lightweight, flexible option that runs on almost anything, including a Raspberry Pi.
Our pick
TrueNAS for data integrity; OMV for low-power builds
Key differences
| Feature | TrueNAS | OpenMediaVault |
|---|---|---|
| Default filesystem | ZFS | ext4/Btrfs/others |
| RAM needs | Higher (ZFS) | Low |
| Raspberry Pi | Not supported | Fully supported |
| Apps | SCALE apps & VMs | Docker via OMV-Extras |
| Data integrity | Excellent (checksums) | Filesystem-dependent |
Verdict
Pick TrueNAS when data integrity matters most and you can give it enough RAM for ZFS. Pick OpenMediaVault for a Raspberry Pi or an older PC where you want a simple, light NAS with flexible filesystem choices.
