How We Tested
To find the best media hubs, I evaluated 12 different NAS units based on three critical media scenarios: 4K hardware transcoding efficiency, peak read/write speeds over 2.5GbE networks, and software ecosystem maturity. I specifically tested each unit’s ability to serve three simultaneous 4K streams to different devices (Apple TV, Android phone, and a web browser) while running a background RAID rebuild to simulate real-world hardware stress.
Best NAS for Home Media Libraries: Detailed Reviews
Synology DiskStation DS423+ View on Amazon
| Drive Bays | 4x 3.5″ or 2.5″ SATA |
|---|---|
| Processor | Intel Celeron J4125 (4-core) |
| RAM | 2GB DDR4 (Expandable to 6GB) |
| M.2 Slots | 2x NVMe (Cache or Storage Pools) |
| Network Ports | 2x 1GbE (Link Aggregation supported) |
The Synology DS423+ is the “Goldilocks” NAS for media collectors. While newer models like the DS923+ have moved to more powerful Ryzen chips, those processors lack an integrated GPU, leaving you stranded with software transcoding that chokes on 4K files. I found the DS423+, with its Intel Celeron J4125, much more capable in a media environment. In my testing, it handled two simultaneous 4K HDR to 1080p transcodes without the CPU usage crossing 30%. This is vital if you share your library with friends who might have slower internet connections.
The DSM 7.2 operating system remains the gold standard for ease of use. Setting up a Plex Media Server took me less than five minutes via the Package Center. I particularly appreciate the two M.2 NVMe slots; by adding a cheap SSD, I noticed the Plex poster art and metadata loaded almost instantly on my TV client. The only real drawback is the lack of a native 2.5GbE port, which feels slightly dated in 2026. However, for media streaming, the stability and transcoding prowess outweigh the raw file transfer speeds. You should skip this if you need 10GbE speeds for professional 8K video editing workflows.
- Hardware transcoding via Intel QuickSync is flawless for Plex Pass
- Best-in-class software (DSM) with excellent mobile apps
- NVMe slots can now be used for actual storage pools, not just cache
- Limited to 1GbE network ports without expensive workarounds
- Included 2GB of RAM is stingy; you’ll want to upgrade it immediately
Asustor AS5402T Nimbustor 2 Gen2 View on Amazon
| Drive Bays | 2x 3.5″ or 2.5″ SATA |
|---|---|
| Processor | Intel Celeron N5105 (4-core) |
| RAM | 4GB DDR4 (Expandable to 16GB) |
| M.2 Slots | 4x NVMe Gen3 |
| Video Out | HDMI 2.0b |
The Asustor AS5402T is a hardware beast that puts more expensive brands to shame. For a mid-range price, you get an Intel N5105 processor which is significantly faster than the chips found in budget Synology or QNAP units. In my tests, the dual 2.5GbE ports were a game changer; when bonded, I saw transfer speeds north of 500MB/s, making it much faster to dump a 60GB 4K Blu-ray rip onto the server. Unlike the premium pick, this offers a fantastic features-per-dollar ratio, especially with four integrated NVMe slots for crazy-fast caching.
The AS5402T also features an HDMI 2.0b port, meaning you can plug it directly into your TV and use it as a media player via ASUSTOR Portal. While the ADM software isn’t quite as polished as Synology’s, it’s highly customizable and supports Docker containers for advanced users wanting to run “the -arrs” (Radarr, Sonarr, etc.) alongside their media server. You should skip this if you prefer a “set it and forget it” software experience with the most refined mobile apps.
- Dual 2.5GbE ports as standard for fast file transfers
- HDMI output allows direct connection to home theater systems
- Supports up to 16GB of RAM for heavy Docker usage
- ADM software interface feels a bit dated compared to competitors
- Fan can be audible in quiet rooms under heavy load
QNAP TS-233 2-Bay Personal Cloud View on Amazon
| Drive Bays | 2x 3.5″ SATA |
|---|---|
| Processor | ARM 4-core 2.0GHz |
| RAM | 2GB (Non-expandable) |
| Power Usage | ~10W (Typical) |
| Network Ports | 1x 1GbE |
The QNAP TS-233 is the ideal “first NAS” for someone who wants to move away from Google Photos or single-drive external backups. It’s incredibly compact and runs almost silently, making it perfect for a living room bookshelf. While the ARM processor isn’t a transcoding powerhouse, it handles direct-play 4K streaming beautifully. If your media player (like a Shield TV or Apple TV) can handle the video codec natively, the TS-233 serves the files with zero lag.
During my month with the unit, I was impressed by how little power it drew—barely more than a smart lightbulb. However, you must be honest about your needs: the 2GB of RAM is soldered and cannot be upgraded, and it will struggle if you try to run multiple background apps while streaming. It’s a dedicated file server, not a multitasking computer. You can skip this if you need to transcode 4K HDR Blu-ray rips for remote viewing on a phone.
- Extremely affordable and power-efficient
- Quiet operation is perfect for home office or media consoles
- NPU speeds up AI photo recognition in QNAP QuMagie
- RAM is not upgradeable, limiting long-term growth
- No hardware transcoding support for many Plex formats
Synology DiskStation DS224+ View on Amazon
| Drive Bays | 2x 3.5″ or 2.5″ SATA |
|---|---|
| Processor | Intel Celeron J4125 (4-core) |
| RAM | 2GB (Expandable to 6GB) |
| Max Raw Capacity | ~40TB (with 20TB drives) |
| Network Ports | 2x 1GbE |
The DS224+ is effectively a two-bay version of my top pick. It uses the same J4125 processor, meaning you get that all-important hardware transcoding in a smaller, cheaper footprint. In my testing, it performed identically to the DS423+ for single-stream 4K transcoding. It’s the perfect niche pick for apartment dwellers or people who don’t plan on hoarding 100TB of data.
While you lose the NVMe slots and the extra bays for RAID 5/6, you still get the full Synology software suite. I found it exceptionally easy to set up as a music server using Plexamp, providing a high-fidelity alternative to Spotify. It’s the most sensible choice for a small family library. You should skip this if you anticipate your library growing beyond 20TB of usable space within the next two years.
- Same powerful transcoding engine as more expensive 4-bay models
- One of the most energy-efficient x86 NAS units available
- Excellent support for 3rd party apps like Home Assistant
- Two-bay limit makes future storage expansion difficult
- No M.2 slots for SSD caching or storage

Frequently Asked Questions
Can the Synology DS423+ transcode 4K HDR content in Plex?
Yes, provided you have a Plex Pass subscription. The DS423+ uses the Intel UHD Graphics 600 engine, which supports hardware-accelerated HDR-to-SDR tone mapping. In my testing, it handled 4K HDR HEVC streams with ease, converting them to 1080p for remote clients without stuttering. Without Plex Pass, the NAS relies on software transcoding, which will cause the CPU to hit 100% and the video to buffer constantly.
Should I buy the Synology DS923+ or the DS423+ for a media library?
For a media-centric library, the older DS423+ is actually superior. The DS923+ uses an AMD Ryzen R1600 processor, which is powerful for file management but lacks an integrated GPU. This means the DS923+ cannot do hardware transcoding in Plex. If your playback devices aren’t 100% capable of direct playing every format (like subtitles or high-bitrate HEVC), the DS423+ will provide a much smoother viewing experience.
Is it a mistake to use “Desktop” hard drives in a NAS?
Yes, it is a significant mistake. Desktop drives (like Western Digital Blue) are designed to run for 8 hours a day and aren’t built to handle the constant vibrations of a multi-bay enclosure. You should always use NAS-specific drives like WD Red Plus or Seagate IronWolf. These are rated for 24/7 operation and feature vibration sensors that prevent the head-crashes and data loss common in multi-drive setups.
Do I need 2.5GbE or 10GbE networking for a home Plex server?
For simply streaming movies, 1GbE is plenty; even a high-bitrate 4K Blu-ray rip rarely exceeds 120Mbps. However, faster networking (2.5GbE+) is a massive time-saver for the “ingestion” phase. If you are transferring 2TB of new movies from your PC, a 2.5GbE connection will finish the job in about 3 hours, whereas 1GbE will take nearly 7 hours. If you’re a frequent “hoarder,” prioritize 2.5GbE.
When is the best time of year to find deals on NAS enclosures?
NAS hardware typically sees its deepest discounts during Amazon Prime Day (July) and Black Friday. Unlike laptops, NAS models have long lifecycles (3-5 years), so you don’t need to worry about a model becoming “obsolete” a month after you buy it. If you see a 15-20% discount on a Synology Plus-series or QNAP Intel-based unit, that is usually the floor price.
Final Verdict
If you are building a serious Plex server for a family and need rock-solid 4K transcoding, the Synology DS423+ is the only choice that makes sense. If you are a performance enthusiast who wants the fastest file transfers and plans to tinker with Docker, the Asustor AS5402T offers much better hardware for your money. For those on a strict budget who just want to stream local files to an Apple TV, the QNAP TS-233 is a fantastic entry point. The NAS market is moving toward higher-speed networking, so investing in 2.5GbE today will likely save you an upgrade in two years.
