Network Attached Storage (NAS) is the backbone of a home lab — a central place to store files, back up PCs, run virtual machines, and serve media. You have two options: buy a pre-built appliance (Synology, QNAP) or build your own with TrueNAS. Each has a clear use case.
Pre-Built NAS: Synology and QNAP
Synology: The Polished Choice
Synology’s DSM (DiskStation Manager) operating system is the gold standard for NAS software. It’s intuitive, actively maintained, and the app ecosystem covers almost every use case.
Popular models:
- DS223: 2-bay, ~$300 (no drives) — home backup, Plex, photos
- DS923+: 4-bay, AMD Ryzen R1600, ~$600 — prosumer home lab
- DS1522+: 5-bay, ~$700 — small business or power users
- DS1823xs+: 8-bay, 10GbE built-in, ~$1,500 — serious lab
DSM highlights:
- Synology Photos: Google Photos replacement, facial recognition, mobile sync
- Surveillance Station: 2 free IP camera licenses
- Synology Drive: Dropbox-like sync to all devices
- Active Backup for Business: free PC backup software with deduplication
- Hyper Backup: scheduled encrypted cloud backups
Synology’s weakness: the hardware is deliberately limited (QNAP competes on raw hardware), and Synology increasingly restricts drives to their certified list (unofficial drives trigger warnings).
QNAP: More Hardware Power
QNAP packs more RAM, faster CPUs, and often includes 2.5G or 10G Ethernet by default. Their QTS operating system is more complex but more powerful.
Popular models:
- TS-464: 4-bay, Intel Celeron N5095, ~$450
- TS-873A: 8-bay, AMD Ryzen V1500B, 2.5G ports, ~$900
- TVS-h874: 8-bay, Intel Core i5-12400, 10GbE + 2.5GbE, ~$1,600
QNAP’s strength: better value for raw compute power, PCIe expansion slots on higher-end models (add your own NIC or NVMe cache), and support for running VMs and containers more comfortably.
DIY NAS with TrueNAS SCALE
TrueNAS SCALE is a Debian-based, open-source NAS operating system with enterprise-grade ZFS storage.
Hardware you’ll need:
- CPU: Any modern Intel/AMD — Celeron N5105 (eco) to Ryzen 9 (workstation)
- RAM: 8GB minimum; 16–32GB recommended for ZFS ARC cache
- Boot drive: 32GB+ USB drive or small SSD (kept separate from storage)
- Storage drives: any combination of HDD/SSD
- Case: Silverstone CS381 (8 bay), Jonsbo N3 (5-bay ITX), or repurposed server
Example DIY 8-bay NAS build:
| Part | Model | Price |
|---|---|---|
| Platform | Intel N100 mini-ITX board | ~$150 |
| RAM | 32GB DDR4 | ~$55 |
| Case | Fractal Node 804 | ~$100 |
| HBA (if needed) | LSI 9211-8i (HBA mode) | ~$50 used |
| Boot drive | 32GB USB 3.0 | $10 |
| Total (no drives) | ~$365 |
Same capacity would cost ~$500–600 for a Synology DS1522+.
TrueNAS SCALE Features
- ZFS: the most reliable filesystem for data integrity — checksumming, copy-on-write, snapshots, send/receive replication
- Apps: Docker containers via TrueNAS Apps (Home Assistant, Plex, Nextcloud, etc.)
- VMs: full KVM virtualization — run Windows or Linux VMs alongside your NAS
- SMB/NFS/iSCSI: all major sharing protocols supported
- 2FA and ACLs: enterprise-grade permission management
TrueNAS weakness: steeper learning curve, no polish of DSM, troubleshooting requires CLI comfort.
ZFS on DIY vs Synology
Synology uses their proprietary Btrfs or ext4 filesystem. ZFS (DIY/TrueNAS) offers superior data integrity through checksumming — every read verifies data hasn’t silently corrupted. For long-term data storage, ZFS is technically superior.
However, Synology’s Btrfs implementation does support snapshots and basic integrity checking — adequate for most home users.
Drive Compatibility
Synology: increasingly enforces an approved drive list. Unapproved drives work but generate warnings in DSM. Some features (WD, Seagate “Synology edition” drives) are restricted.
QNAP: more lenient on drive compatibility.
DIY/TrueNAS: any drive works. Preferred: CMR drives (not SMR) for ZFS — Seagate IronWolf, WD Red Plus, WD Gold.
Decision Framework
| Situation | Recommendation |
|---|---|
| Non-technical user, just wants it to work | Synology |
| Wants best software experience + remote access | Synology |
| Needs VMs + containers alongside NAS | QNAP or TrueNAS |
| Power user, comfort with Linux, wants ZFS | TrueNAS DIY |
| Maximum budget efficiency | TrueNAS DIY |
| 4–6 drives, Plex, photos, PC backup | Synology DS923+ |
For first-time NAS users, Synology’s DSM is genuinely excellent and justifies the premium. For anyone comfortable with Linux and wanting full control, TrueNAS SCALE is a more powerful and cost-effective long-term solution.
