Home server RAID poll: what does the homelab community use?
The homelab community ran a poll asking what RAID setup people use on their home servers. For anyone running a Mac mini as a home server, this is a practical data-protection question worth following.
RAID is a way of combining multiple storage drives so that if one fails, your data survives — or so that read/write speeds improve. When you run a home server, picking the right RAID level is a real decision that affects how safe your files are and how much storage you actually get to use.
Community responses covered RAID 1 (mirroring — two drives hold identical copies), RAID 5 (spreads data across three or more drives with recovery info), software RAID via ZFS, and simply relying on backups instead of RAID at all. For Mac mini operators with limited internal storage, the discussion is a useful reference for pairing external drives or a NAS to get similar protection.
Key points
- RAID 1 mirrors data across 2 drives — one can fail and you lose nothing
- RAID 5 needs 3+ drives, tolerates one failure, and wastes less space than mirroring
- ZFS handles RAID and automatic data-integrity checks in software, no special hardware needed
- RAID is not a backup — ransomware or accidental deletion can still wipe everything
- Mac mini users can mirror an external drive or connect a NAS to get comparable protection
