Why Your NAS Choice Matters for Plex
Plex can run on anything—a laptop, a mini PC, even a Raspberry Pi. But a NAS designed for media serving offers unique advantages:
- Always on: No more "is the server running?"
- Redundant storage: Drive failures don't kill your library
- Low power: Pennies per day to run
- Expandable: Grow your storage over time
- Multi-purpose: Run more than just Plex
But not all NAS devices are created equal. Plex has specific needs—particularly around transcoding—that rule out many options.
Let's find the right one for you.

Plex Server Requirements: What to Look For
Before we get to specific models, understand what Plex actually needs.
CPU: The Transcoding Factor
This is the most misunderstood aspect of Plex hardware.
Direct Play (ideal): Your server streams the file exactly as-is. The client device does all the work. Any CPU can handle this.
Transcoding (CPU-intensive): Your server converts the file in real-time because:
- The client can't play the format (e.g., iPhone won't play MKV)
- Bandwidth is limited (remote streaming on slow connection)
- Resolution needs adjustment (4K source, 1080p playback)
Hardware transcoding (Plex Pass required): Uses the GPU's video engine to transcode with minimal CPU load. This is the game-changer.
Intel QuickSync is king for hardware transcoding. Intel's integrated GPUs can handle multiple 4K transcodes simultaneously while using a fraction of the power.
Without Intel QuickSync (AMD processors, ARM chips):
- Software transcoding works but maxes out CPU
- Multiple streams bring the server to its knees
- 4K transcoding is essentially impossible
What This Means for NAS Selection
| Your Use Case | Minimum CPU |
|---|---|
| All clients support direct play | Any processor works |
| Occasional 1080p transcoding | Intel Celeron N-series acceptable |
| Regular 1080p transcoding, some 4K | Intel Core i3 or better |
| Multiple simultaneous 4K transcodes | Intel Core i5/i7 or dedicated GPU |
RAM: More Than You Think
Plex official specs say 2GB minimum. Reality check:
| Library Size | Recommended RAM |
|---|---|
| < 1,000 items | 4GB |
| 1,000-10,000 items | 8GB |
| 10,000+ items | 16GB+ |
| Running additional services | Add 4-8GB |
RAM is upgradable on most NAS devices. Start with what ships and add more if needed.
Storage Capacity: Plan for Growth
Media libraries grow. A lot.
Rough storage math:
- Average 1080p movie: 8-10GB
- Average 4K HDR movie: 40-60GB
- Average TV season: 20-40GB
My recommendation: Buy 50% more capacity than you think you need. You'll use it.
Network: Speed Matters
For streaming within your home network:
| Network Speed | Supports |
|---|---|
| 1 Gigabit (1GbE) | Multiple 1080p streams, single 4K stream |
| 2.5 Gigabit | Multiple 4K streams, fast file transfers |
| 10 Gigabit | Overkill for home streaming, great for large file transfers |
Most budget NAS devices come with 1GbE. Mid-range often includes 2.5GbE. High-end offers 10GbE or expansion slots.

Hard Drive Recommendations
A NAS is only as good as its drives. Don't cheap out here.
Best Options for Media Storage
| Drive | Capacity | NAS-Optimized? | Price | [AFFILIATE] |
|---|---|---|---|---|
| WD Red Plus | 8TB | Yes, CMR | ~$180 | WD Red Plus 8TB |
| WD Red Pro | 8TB | Yes, CMR | ~$250 | WD Red Pro 8TB |
| Seagate IronWolf | 8TB | Yes, CMR | ~$200 | Seagate IronWolf 8TB |
| Seagate Exos | 16TB | Yes, Enterprise | ~$220 | Seagate Exos 16TB |
My pick: Seagate Exos offers incredible value—enterprise reliability at consumer prices.
RAID Configuration Recommendations
| Bay Count | Recommended RAID | Usable Space | Redundancy |
|---|---|---|---|
| 2 bay | RAID 1 (mirror) | 50% | 1 drive failure |
| 4 bay | RAID 5 | 75% | 1 drive failure |
| 4 bay | RAID 6 | 50% | 2 drive failures |
| 5+ bay | RAID 6 | ~67% | 2 drive failures |
For media that can be re-ripped or re-downloaded, RAID 5 is fine. For irreplaceable content, RAID 6.
Remote Access: VPN or Not?
Accessing your Plex server remotely? Consider your options:
Plex Relay (Built-in, Limited)
Free for all Plex users, but:
- 1 Mbps bandwidth limit (free accounts)
- 2 Mbps limit (Plex Pass)
- Routes through Plex's servers
- Not ideal for high-quality streaming
Direct Connection
Port forward Plex on your router:
- Exposes your IP to the internet
- No bandwidth limits
- Requires your ISP to allow port forwarding
VPN (Recommended)
Connect to your home network via VPN:
- End-to-end encryption
- Access all home resources, not just Plex
- No exposed services to the internet
NordVPN or ExpressVPN for remote devices, or run VPN server on the NAS itself.
Alternative: Mini PC + DAS Instead of NAS
For some users, a separate server plus storage makes more sense.
The setup:
- Mini PC (Intel NUC, GEEKOM) as Plex server
- DAS (Direct Attached Storage) or external drives for media
- Less integrated, but potentially cheaper
When this makes sense:
- You already have a powerful mini PC
- You don't need always-on network storage for other purposes
- You want more CPU power than NAS allows
Recommended hardware:
- Intel NUC 13 Pro Intel NUC 13 - Excellent for Plex
- GEEKOM IT13 GEEKOM IT13 - Great value
- Orico 4-Bay DAS Orico DAS - External enclosure
The Bottom Line
For most Plex users, here's my recommendation:
Budget setup:
- Synology DS224+ (~$300) [AFFILIATE]
- 2x WD Red Plus 8TB (~$360) [AFFILIATE]
- Total: ~$660
Sweet spot:
- QNAP TS-464 (~$450) [AFFILIATE]
- 4x Seagate IronWolf 8TB (~$800) [AFFILIATE]
- Total: ~$1,250 with room to grow
Power user:
- QNAP TVS-674 (~$1,200) [AFFILIATE]
- 6x Seagate Exos 16TB (~$1,300) [AFFILIATE]
- Total: ~$2,500 for ~80TB usable storage
FAQ
Do I need Plex Pass for hardware transcoding? Yes. Hardware transcoding requires Plex Pass ($95 lifetime or $5/month). Software transcoding works without it.
Can I run other services on my Plex NAS? Absolutely. Synology and QNAP support Sonarr, Radarr, Jackett, Home Assistant, and dozens of other services. Consider extra RAM.
What if my server is only for local streaming? If all your clients support direct play (Shield, Apple TV, smart TV), you don't need transcoding capability. Focus on storage capacity and network speed instead.
Should I use SSDs in my NAS? For media storage, HDDs are more cost-effective. Consider an NVMe cache SSD if your NAS supports it—improves metadata and database performance.
How do I move my existing Plex library to a NAS?
- Set up Plex on NAS
- Point it to your media (copied or moved to NAS)
- Use Plex's "import watch history" to preserve your progress
- Alternatively, backup and restore the Plex database
Your media deserves a real home. Choose wisely, set it up right, and enjoy.
