Choosing your first Network Attached Storage (NAS) device can feel overwhelming. With dozens of brands, models, and configurations available, where do you even start? In this guide, I’ll walk you through everything you need to know to pick the perfect NAS for your needs.
What is a NAS and Why Do You Need One?
A NAS is a dedicated file server that connects to your network and provides centralized storage accessible by all your devices. Think of it as your personal cloud—but one you own and control.
Why Choose a NAS Over Cloud Storage?
Privacy: Your data never leaves your home
Cost: No monthly subscriptions forever
Speed: Gigabit transfers on your local network
Capacity: Terabytes of storage for the price of a few months of cloud
Control: You decide what runs on it
What to Look for in a First NAS
Before diving into specific recommendations, understand these key factors:
1. Drive Bays
NAS devices come with 1, 2, 4, or more drive bays. More bays = more capacity and redundancy options.
- 1-bay: Cheapest, but no redundancy (if the drive fails, you lose everything)
- 2-bay: Sweet spot for beginners—allows mirroring for data protection
- 4-bay: Best for growing collections and flexible RAID configs
- 5+ bays: Overkill for most home users
Recommendation: Start with a 2-bay or 4-bay NAS.
2. CPU and RAM
A faster processor means:
- Better media transcoding (Plex, Jellyfin)
- More simultaneous users
- Faster file indexing
- Ability to run Docker containers
Minimum: Intel Celeron or equivalent, 2GB RAM
Recommended: Intel Pentium/i3 or AMD Ryzen, 4GB+ RAM
3. Software Ecosystem
The operating system matters more than you think. It determines:
- How easy setup will be
- What features are available
- Whether you can install third-party apps
Easiest: Synology DSM, QNAP QTS
Most flexible: TrueNAS, Unraid
Most powerful: Proxmox (but steeper learning curve)
4. Budget
NAS prices range from $150 to $1,500+ (excluding drives).
Entry-level: $150-300 (2-bay, basic features)
Mid-range: $300-600 (4-bay, Intel CPU, Docker support)
High-end: $600+ (enterprise features, 10GbE, ECC RAM)
Top NAS Recommendations for Beginners

What About DIY NAS?
Building your own NAS is absolutely an option and often provides better value.
When DIY Makes Sense:
- You want maximum customization
- You’re comfortable with Linux
- You need specific hardware (10GbE, ECC RAM, etc.)
- You’re a tinkerer who enjoys the process
Popular DIY Options:
TrueNAS Core (free, ZFS-based, rock-solid)
Unraid ($60-$130, easiest DIY option)
OpenMediaVault (free, Debian-based)
Proxmox (free, VM + storage combo)
DIY Cost Example:
Comparable to a DS224+ but with more flexibility.
When to Buy Pre-Built:
- You want warranty and support
- You value your time over savings
- You want the simplest possible setup
- You need proven reliability
Choosing the Right Hard Drives
Your NAS is only as good as the drives inside it.
NAS-Specific Drives
Regular desktop drives aren’t designed for 24/7 operation. NAS drives include:
- Vibration resistance (for multi-drive setups)
- 24/7 operation rating
- Longer warranties (typically 3-5 years)
- Better error recovery
Recommended Brands:
WD Red Plus: Consumer favorite, CMR, reliable
Seagate IronWolf: Good value, CMR, includes rescue service
Toshiba N300: Budget option, solid performer
Avoid: WD Red SMR drives (the non-Plus models)
How Much Capacity?
Start with what you need now, not what you might need in 5 years. Drives get cheaper over time.
Typical needs:
- Documents/backups only: 2TB per user
- Photos + videos: 4-8TB
- Media server (1080p): 4-8TB
- Media server (4K): 12-20TB+
Pro tip: Buy drives in pairs for mirroring/RAID.
RAID Configurations Explained (Simply)
RAID combines multiple drives for speed, redundancy, or both.
For Beginners:
RAID 1 (Mirroring) - 2 drives
Capacity: 50% (one drive for data, one for copy)
If 1 drive fails: Your data is safe
Best for: 2-bay NAS users who want protection
SHR (Synology Hybrid RAID) - 2+ drives
Capacity: Optimized based on drive sizes
If 1 drive fails: Your data is safe
Best for: Synology users with mismatched drive sizes
RAID 5 - 3+ drives
Capacity: 67-80% (depending on drive count)
If 1 drive fails: Your data is safe
Best for: 4-bay users balancing capacity and protection
JBOD (Just a Bunch of Disks)
Capacity: 100%
If 1 drive fails: You lose that drive’s data
Only use if: You have backups elsewhere
Essential NAS Features for Self-Hosting
Docker Support
The ability to run Docker containers turns your NAS into an app platform:
- Nextcloud: Personal cloud storage
- Vaultwarden: Password manager
- Plex/Jellyfin: Media server
- Paperless-ngx: Document management
- Pi-hole: Network-wide ad blocking
Both Synology and QNAP support Docker natively.
Remote Access
Access your files from anywhere:
QuickConnect (Synology): Zero-config remote access
myQNAPcloud (QNAP): Similar to QuickConnect
VPN: Most secure option (WireGuard recommended)
Cloudflare Tunnel: Free, secure, no port forwarding
Backup Options
Your NAS should back up to:
- External USB drive (local backup)
- Another NAS or PC (network backup)
- Cloud (offsite backup - B2, Glacier, etc.)
Follow the 3-2-1 rule: 3 copies, 2 different media, 1 offsite.
Setup Tips for First-Time NAS Users
1. Update Firmware First
Before loading data, update to the latest OS version. This ensures bug fixes and security patches.
2. Configure Notifications
Set up email alerts for:
- Drive failures
- Temperature warnings
- Update availability
- Backup failures
3. Enable SMART Monitoring
SMART data predicts drive failures. Most NAS software can run monthly tests and alert you.
4. Set Up Scheduled Tasks
Automate:
- Weekly SMART tests
- Monthly scrubbing (RAID integrity check)
- Daily/weekly backups
5. Create Separate Users
Don’t use the admin account for daily access. Create user accounts with appropriate permissions.
Common Mistakes to Avoid
1. No Redundancy
Running JBOD or RAID 0 without backups is gambling with your data. Always use mirroring or parity.
2. Buying Too Small
“I’ll never need more than 2TB” — you, before discovering 4K Remux files. Give yourself room to grow.
3. Skipping Backups
RAID is not backup. Drives can fail simultaneously, or you might accidentally delete files. Back up critical data.
4. Cheap Drives
Saving $20 on no-name drives isn’t worth the risk. Stick with WD, Seagate, or Toshiba NAS-rated drives.
5. Ignoring Network Bottlenecks
Your gigabit network limits transfers to ~125MB/s. For best performance:
- Use wired connections
- Consider 2.5GbE or better
- Don’t rely on WiFi for large transfers
My Recommendation
For most beginners, I’d recommend:
Best overall: Synology DS224+ with 2x 4TB WD Red Plus drives
Total cost: ~$500
Usable capacity: 4TB (mirrored)
This combo offers:
- Dead-simple setup
- Excellent software
- Room to run Docker apps
- Reliable hardware
- Strong community support
If you need more bays, step up to the DS923+ or consider a DIY build with TrueNAS.
Conclusion
A NAS is one of the best investments in your self-hosting journey. It centralizes your data, protects it with redundancy, and provides a platform for running services 24/7.
Start with a 2-bay Synology or QNAP, use quality drives, and enable mirroring. As your needs grow, you can always expand or migrate to a larger NAS—your data comes with you.
The most important thing? Just start. Pick a device, set it up, and begin moving your data off cloud services you don’t control.
