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:

  1. 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.
  2. At least 4GB RAM (8GB preferred) — Plex uses RAM for metadata, thumbnails, and stream buffering.
  3. Gigabit Ethernet minimum — streaming 4K requires sustained 80-100 Mbps. 2.5GbE is future-proof.
  4. SATA bays for large drives — 3.5” bays accept the cheapest high-capacity storage (4-16TB drives).

Synology DS224+ — Best for Simplicity

Synology DS224+

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

QNAP TS-264

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.
