Best Budget NAS for Plex and Home Media Server 2026: Synology vs QNAP
Keeping a full desktop PC running 24/7 just to serve Plex costs €30-50/month in electricity alone. A dedicated NAS draws 15-25 watts, runs silently, and handles media serving, backups, and downloads without babysitting.
Quick answer: The Synology DS224+ is the best budget Plex NAS for most people — Intel hardware transcoding, dead-simple setup, excellent Plex integration, and Synology’s mature ecosystem. If you want more raw power per euro and don’t mind a slightly more complex interface, the QNAP TS-264 gives you more RAM and a faster CPU at a similar price.
What Makes a Good Plex NAS?
Not every NAS can run Plex well. These are the non-negotiable requirements:
- Intel/AMD CPU with hardware transcoding — ARM chips can’t transcode. If any device plays your media in a different format than the original file, the NAS needs to transcode on-the-fly.
- At least 4GB RAM (8GB preferred) — Plex uses RAM for metadata, thumbnails, and stream buffering.
- Gigabit Ethernet minimum — streaming 4K requires sustained 80-100 Mbps. 2.5GbE is future-proof.
- SATA bays for large drives — 3.5” bays accept the cheapest high-capacity storage (4-16TB drives).
Head-to-Head: Synology DS224+ vs QNAP TS-264
| Spec | Synology DS224+ | QNAP TS-264 |
|---|---|---|
| Price | ~€320-350 | ~€330-370 |
| CPU | Intel Celeron J4125 (4C/4T) | Intel Celeron N5095 (4C/4T) |
| RAM | 2 GB DDR4 (expandable to 6GB) | 8 GB DDR4 (expandable to 16GB) |
| Drive bays | 2x 3.5” SATA | 2x 3.5” SATA |
| M.2 slots | 0 | 2x NVMe (cache/storage) |
| Network | 1x 1GbE | 2x 2.5GbE |
| USB | 2x USB 3.2 | 1x USB 3.2 + 1x USB 2.0 |
| HDMI | ❌ | ✅ (direct TV output) |
| 4K transcodes | 1-2 simultaneous | 2-3 simultaneous |
| Power consumption | ~15W idle | ~18W idle |
| Noise | Very quiet | Quiet |
| OS | DSM 7.x | QTS 5.x |
| Plex integration | Native package | Native package |
Synology DS224+ — Best for Simplicity
Synology’s DSM operating system is the reason most people choose this brand. The interface is browser-based, looks like a desktop OS, and installing Plex is literally “click install from the package center.” No terminal commands, no Docker configuration, no troubleshooting.
Strengths
- Setup in 15 minutes — insert drives, power on, follow the web wizard, install Plex. Done.
- DSM ecosystem — Synology Photos (Google Photos replacement), Synology Drive (Dropbox replacement), and Hyper Backup (automated offsite backups) all work flawlessly.
- Security updates — Synology’s security track record is excellent. Automatic updates, 2FA, and active patching.
- Community and documentation — every possible issue has been solved and documented on Reddit/forums.
- Power efficiency — 15W idle means ~€20/year in electricity.
Weaknesses
- Only 2GB RAM — functional for Plex but tight if you run other services simultaneously. Upgrading to 6GB costs ~€25.
- No M.2 slots — can’t add SSD cache for faster metadata browsing.
- 1GbE only — fine for most homes but limits multi-stream 4K scenarios. A USB 2.5GbE adapter works but adds cost.
- Transcoding ceiling — the J4125 handles 1-2 4K transcodes; a third stream will stutter.
Verdict
Best for: First-time NAS buyers who want zero headaches. If “it just works” matters more than maximum performance, the DS224+ delivers that Apple-like experience in the NAS world.
QNAP TS-264 — Best Value for Power Users
The QNAP trades Synology’s polish for raw specs. 8GB RAM (4x more), a faster N5095 CPU, dual 2.5GbE ports, M.2 SSD slots, and HDMI output — all at a near-identical price. If you plan to run Docker containers, VMs, or multiple services alongside Plex, the QNAP gives you headroom.
Strengths
- 8GB RAM out of the box — enough for Plex + Docker + Pi-hole + download managers simultaneously.
- Faster CPU — the N5095 benchmarks 20-30% faster than the J4125 in transcoding tasks.
- Dual 2.5GbE — link aggregation or separate networks for streaming and backups.
- M.2 NVMe slots — add SSD cache for instant thumbnail generation and snappy Plex browsing.
- HDMI output — connect directly to a TV and use the NAS as a media player (no Chromecast needed).
Weaknesses
- QTS learning curve — more powerful but less intuitive than DSM. First-time users will spend more time in settings.
- Security history — QNAP has had more publicized vulnerabilities than Synology. Keep auto-updates enabled.
- Louder fans — the extra power means slightly more thermal output and fan noise (still quiet, but noticeable in a bedroom).
- Bulkier — physically larger unit than the compact DS224+.
Verdict
Best for: Users who want a NAS that does more than just Plex — Docker, VMs, download automation (Sonarr/Radarr), and home network services. The extra RAM and CPU make all the difference when multitasking.
Which Drives to Buy?
The NAS is empty — you need drives. For Plex media storage:
| Drive | Capacity | Best for | Price |
|---|---|---|---|
| WD Red Plus 4TB | 4 TB | Starter libraries, quiet | ~€100 |
| Seagate IronWolf 8TB | 8 TB | Growing collections, 4K | ~€170 |
| WD Red Plus 12TB | 12 TB | Large libraries, future-proof | ~€230 |
Our pick: 2x Seagate IronWolf 8TB in RAID 1 (mirrored). Gives you 8TB of protected storage — enough for ~400 movies in 1080p or ~130 in 4K.
Total Cost Breakdown
| Setup | NAS + Drives | Annual electricity | Total Year 1 |
|---|---|---|---|
| Synology DS224+ + 2x4TB | ~€550 | ~€20 | ~€570 |
| QNAP TS-264 + 2x8TB | ~€700 | ~€25 | ~€725 |
| Old PC running 24/7 | €0 (existing) | ~€300-500 | €300-500/yr ongoing |
The NAS pays for itself within 1-2 years versus running a desktop PC 24/7.
Our Verdict
Synology DS224+ if you want the easiest possible path to a working Plex server. Buy, install, forget.
QNAP TS-264 if you’re comfortable with slightly more complexity and want a device that grows with you into Docker, automation, and advanced networking.
Both are excellent. Neither will disappoint. The DS224+ wins on experience; the TS-264 wins on specs.
Prices are diskless (drives sold separately). Check current RAM expansion pricing — upgrading the Synology to 6GB is highly recommended for Plex.
