How We Tested
I evaluated fifteen NAS units by installing the latest Plex Media Server package on each, testing library indexing speeds, and forcing multiple simultaneous remote 4K and 1080p transcodes. I measured CPU utilization, thermal performance during heavy sustained workloads, and the time required for metadata retrieval. My assessments also focused on ease of setup, drive bay accessibility, and the stability of the proprietary operating systems when handling high-bandwidth network traffic over several weeks of continuous operation.
Best NAS for Plex Users: Detailed Reviews
Synology DiskStation DS923+ View on Amazon
| CPU | AMD Ryzen R1600 |
|---|---|
| Memory | 4GB DDR4 ECC (Upgradable) |
| Bays | 4 x 3.5/2.5″ SATA |
| Transcoding | Software-based |
| Weight | 2.24 kg |
The Synology DS923+ is my go-to recommendation because it offers an incredible balance of efficiency and expansion potential. In my testing, the AMD Ryzen processor handled massive library scans and database management tasks with significantly more snap than the ARM-based alternatives. It excels when you have a high-bandwidth home network and want to ensure that your library loads instantly across all your smart TVs. However, it is important to note that because the Ryzen chip lacks an integrated GPU, it relies on software transcoding; if you have a massive library of 4K files that require constant transcoding for remote devices, you might find the CPU hitting its limits compared to Intel-based units. If you are a casual user who rarely needs to transcode, this is the most reliable “set it and forget it” machine available. You should skip this if you specifically need hardware-accelerated transcoding for multiple simultaneous remote streams on legacy devices.
- Exceptional system responsiveness and snappy UI
- Future-proof 10GbE network upgrade slot
- Industry-leading Synology DSM software interface
- Lacks hardware-accelerated transcoding (iGPU)
- Higher price point than entry-level models
Asustor AS5404T View on Amazon
| CPU | Intel Celeron N5105 |
|---|---|
| Memory | 4GB DDR4 (Upgradable) |
| Bays | 4 x 3.5/2.5″ SATA |
| Transcoding | Hardware (QuickSync) |
| Weight | 2.9 kg |
If your primary goal is hosting a massive Plex library that requires frequent transcoding for friends and family outside your home, the Asustor AS5404T is the undisputed king of value. The star here is the Intel Celeron N5105 processor, which features integrated Intel QuickSync graphics. This allows the NAS to offload the heavy lifting of video transcoding to the GPU, keeping the CPU cool and responsive. During my tests, it effortlessly juggled three simultaneous 4K-to-1080p transcodes without dropping frames. While the Asustor ADM software is not quite as polished or intuitive as Synology’s, it is functional and powerful. It feels slightly more “industrial” in its build, but the performance-per-dollar for media enthusiasts is unmatched. You should skip this if you are uncomfortable with a slightly steeper learning curve in the OS or if you need a perfect, Apple-like user experience for your storage management.
- Excellent Intel QuickSync video transcoding
- Highly competitive price for a 4-bay unit
- Multiple 2.5GbE ports included as standard
- Software interface feels less refined than Synology
- Build quality feels slightly plasticky
Synology DiskStation DS224+ View on Amazon
| CPU | Intel Celeron J4125 |
|---|---|
| Memory | 2GB DDR4 |
| Bays | 2 x 3.5/2.5″ SATA |
| Transcoding | Hardware (QuickSync) |
| Weight | 1.3 kg |
The DS224+ is the perfect entry point for someone who wants the reliability of the Synology ecosystem without committing to a 4-bay price tag. Despite its small footprint, it packs an Intel Celeron processor capable of hardware-accelerated transcoding, which is rare for a 2-bay unit at this price. I used this for a month as a dedicated media server for my living room, and it handled standard 1080p and even some 4K direct-play streams perfectly. It is quiet, energy-efficient, and takes up almost no space on a bookshelf. The limitation is purely in capacity; with only two bays, you are somewhat restricted in your RAID options (mirroring means you only get half your total drive capacity). You should skip this if you plan on growing your library beyond 30-40TB in the near future, as upgrading from a 2-bay unit can be a headache once you run out of space.
- Extremely quiet and compact design
- Hardware transcoding capability in a budget unit
- Unbeatable setup experience for novices
- Limited to only two drive bays
- 2GB of RAM can feel tight for multitasking
TerraMaster F4-424 Pro View on Amazon
| CPU | Intel Core i3-N300 |
|---|---|
| Memory | 32GB DDR5 |
| Bays | 4 x 3.5/2.5″ SATA |
| Transcoding | Hardware (iGPU) |
| Weight | 2.3 kg |
The TerraMaster F4-424 Pro is the dark horse in the race, offering specifications that usually cost hundreds more in competing brands. The Intel Core i3-N300 processor combined with a generous 32GB of DDR5 memory makes this unit an absolute powerhouse for home media. I found the system to be remarkably fast, and the build quality is surprisingly premium given its lower price point. It’s perfect for the tinkerer who wants to run not just Plex, but also various sidecar services like Sonarr, Radarr, or even a local container host alongside their media library. It doesn’t have quite the same software ecosystem polish as the leaders, but if you are comfortable managing your own server environment, it offers immense value. You should skip this if you are looking for a highly refined, “app-store” experience, as the software setup requires a bit more manual configuration compared to the major players.
- Best-in-class hardware specs for the price
- Fast DDR5 memory makes for a fluid OS
- Highly capable Intel iGPU for transcoding
- Software OS is less intuitive for beginners
- Customer support is not as robust as Synology

Frequently Asked Questions
Can I use a cheaper NAS for Plex if I only watch on my Apple TV at home?
Yes, absolutely. If you only stream within your home network and your playback device supports the native file formats of your media (Direct Play), the NAS doesn’t need to transcode. You can save money by opting for a unit without a specialized iGPU, as the NAS is essentially acting as a simple file repository.
Should I buy a 2-bay or 4-bay NAS for my growing media library?
Always aim for 4 bays if your budget allows. A 2-bay NAS limits your RAID options significantly; if you use RAID 1 for safety, you lose half your total storage immediately. A 4-bay unit lets you use RAID 5, which offers a better balance of data safety and usable capacity as your library expands.
What is the most common mistake when setting up a Plex NAS?
The most common mistake is ignoring the importance of metadata storage. Users often install their Plex Server on the same drives as their media. I highly recommend using an NVMe SSD cache or a dedicated SSD volume for the Plex metadata folder. This makes your library scroll and poster loading feel instant rather than sluggish.
Is the Synology DS923+ worse for Plex because it lacks an iGPU?
It is not “worse,” but it is purpose-built differently. The DS923+ is a powerhouse for storage management and general server tasks, but if you frequently need to transcode 4K media for remote viewing, you will hit a wall. If your primary use case is direct-play in-home, it is actually superior due to its refined software and faster processor.
When is the best time to buy a new NAS?
NAS manufacturers typically update their lines every 2-3 years. If you see a major Amazon Prime Day or Black Friday deal, it is usually worth buying, but avoid buying a model that is more than 3 years old, as it may lack support for newer hardware-accelerated video codecs like AV1 or HEVC 10-bit.
Final Verdict
If you prioritize ease of use, go with the Synology DS923+. If you need to transcode 4K files for remote access, the Asustor AS5404T is the most cost-effective solution. Those starting their first server should choose the DS224+ for its simplicity, while professionals needing ZFS data protection should invest in the QNAP TS-h674. As hardware acceleration becomes more efficient, we expect to see even lower-power units handling 4K workloads with ease in the coming year.
