Strengths and trade-offs
openmediavault
Strengths
- Very light: runs on old PCs and Raspberry Pi boards
- Free, open source and built on plain Debian
- Does file sharing and backups without extra layers
Trade-offs
- Plain interface with no app store out of the box
- Docker apps need the omv-extras plugin and some command-line setup
- Raspberry Pi install means installing Debian first
TrueNAS
Strengths
- ZFS protects against silent data corruption and makes snapshots easy
- Free, with no drive or user limits
- Large community and very detailed documentation
Trade-offs
- ZFS pools prefer matching drives, so growing storage takes planning
- Needs at least 8 GB of RAM and a separate boot drive
- More settings and storage words to learn than the beginner systems
