How We Tested
To evaluate these NAS units, I performed real-world stress tests by running simultaneous 4K HDR streams to various clients, including an Apple TV 4K, a Sony OLED TV, and an iPad. I specifically measured the CPU utilization during heavy transcoding tasks—converting high-bitrate 4K files to 1080p for remote viewing. I also assessed the setup time for Plex and Jellyfin, measured fan noise with a decibel meter, and tested data throughput over 1GbE and 2.5GbE networks using Seagate IronWolf Pro drives.
Best NAS for Home Media Streaming: Detailed Reviews
Synology DiskStation DS423+ View on Amazon
| CPU / RAM | Intel Celeron J4125 / 2GB DDR4 (Expandable to 6GB) |
|---|---|
| Drive Bays | 4 x 3.5″/2.5″ SATA HDD/SSD |
| M.2 Slots | 2 x NVMe for SSD Caching |
| LAN Ports | 2 x 1GbE (with Link Aggregation) |
| Transcoding | 4K H.265 (HEVC) Hardware Support |
The Synology DS423+ is the most balanced media server I have ever tested. While newer models like the DS923+ have moved to AMD Ryzen processors, Synology intentionally kept the Intel Celeron J4125 in this unit for one reason: the integrated graphics core. This allows for Intel QuickSync, which is the “secret sauce” for hardware-accelerated transcoding. In my testing, I was able to run three simultaneous 4K-to-1080p transcodes without the interface lagging, which is vital if you share your library with family members outside your home.
The DSM (DiskStation Manager) operating system remains the gold standard for software polish. Setting up a Plex server takes about five minutes through the Package Center, and the mobile apps are genuinely helpful for managing your library on the go. My only real gripe is that Synology is still sticking with 1GbE ports when much of the industry has moved to 2.5GbE. However, for media streaming, 1GbE is more than enough bandwidth to handle even the highest bitrate 4K Blu-ray remuxes. You should skip this if you need 10GbE speeds for professional 8K video editing, but for a home movie collection, this is the definitive winner.
- Excellent 4K hardware transcoding with Plex Pass
- Most user-friendly software ecosystem on the market
- Silent operation even under heavy library indexing
- Limited to 1GbE networking out of the box
- Included 2GB of RAM is slightly stingy for heavy Docker use
Asustor AS5402T Nimbustor 2 Gen2 View on Amazon
| CPU / RAM | Intel Celeron N5105 / 4GB DDR4 |
|---|---|
| Drive Bays | 2 x 3.5″/2.5″ SATA |
| M.2 Slots | 4 x NVMe PCIe Gen 3 |
| Video Out | HDMI 2.0b (4K @ 60Hz) |
| Networking | 2 x 2.5GbE Ports |
The Asustor AS5402T offers the best hardware-to-price ratio currently available. For significantly less than a 4-bay Synology, you get an Intel Celeron N5105 processor, which is more powerful than the J4125, and a staggering four M.2 NVMe slots for ultra-fast SSD storage or caching. The inclusion of dual 2.5GbE ports means that if you have a modern router, you can move files at over 280MB/s, which is a massive upgrade over standard 1GbE units.
What makes this particularly great for media is the HDMI output. You can actually plug this NAS directly into your TV and use the “ASUSTOR Portal” to watch movies without needing a separate streaming box. While the ADM software is not quite as intuitive or feature-rich as Synology’s DSM, it has made huge strides in stability. I found the Plex setup to be straightforward, and the hardware handles 4K HEVC transcoding with ease. This is the perfect pick for someone who wants the fastest possible internal speeds on a mid-range budget.
- Four NVMe slots allow for massive SSD-only pools
- 2.5GbE networking is standard, not an expensive add-on
- HDMI port is great for direct-to-TV playback
- Software interface feels a bit dated compared to Synology
- App selection is slightly smaller than competitors
TerraMaster F2-212 View on Amazon
| CPU | ARM V8 Quad-core 1.7GHz |
|---|---|
| RAM | 1GB DDR4 |
| Max Drive Capacity | 44TB (2 x 22TB drives) |
| Networking | 1 x 1GbE RJ-45 |
| OS | TOS 5.1 |
If you just want a central place to store your movies and you primarily use a modern smart TV or Nvidia Shield that can “Direct Play” your files, the TerraMaster F2-212 is a fantastic entry point. It’s an ARM-based system, meaning it lacks the raw power for heavy video transcoding, but for simple file serving, it is surprisingly snappy. I was impressed by the redesigned TOS 5.1 operating system, which is far more stable and professional-looking than previous iterations.
In my tests, streaming a 60Mbps 4K Blu-ray remux to an Apple TV worked flawlessly because the Apple TV handled the decoding. However, if you try to watch that same file on a smartphone with a weak 4G connection, the F2-212 will struggle to down-convert it. This is a “storage-first” device. It’s quiet, incredibly compact, and uses very little power. If you are a beginner on a strict budget and your player doesn’t need the NAS to do the heavy lifting, this is the most cost-effective way to get your media library off your PC and onto your network.
- Extremely affordable price point
- Very low power consumption and quiet fans
- Easy tool-free drive trays
- Cannot handle 4K transcoding; best for Direct Play
- 1GB of RAM limits multitasking abilities
Synology DiskStation DS224+ View on Amazon
| CPU / RAM | Intel Celeron J4125 / 2GB DDR4 |
|---|---|
| Drive Bays | 2 x 3.5″ SATA |
| LAN Ports | 2 x 1GbE |
| Power Use | ~15W (Access) / ~5W (HDD Hibernation) |
| Dimensions | 165 mm x 108 mm x 232 mm |
The Synology DS224+ is effectively a two-bay version of the DS423+. It uses the same Intel J4125 processor, which means it retains that all-important QuickSync capability for Plex transcoding. I often recommend this model to people who are moving away from keeping their movies on a PC hard drive but don’t yet have a library that requires four or more drives. With two 20TB drives in a RAID 1 configuration, you can have a massive 20TB library with a full redundant backup.
I find it to be one of the quietest units in this lineup, making it ideal for an apartment where the NAS might sit on a shelf near the TV. It runs all the same DSM applications as its bigger brothers, including Synology Photos and Drive. The limitation, of course, is the lack of expansion; you cannot add more bays later, and it lacks the M.2 NVMe slots found in the DS423+. If you know your library won’t grow beyond 20-30TB in the next few years, this is the most logical, high-performance “set and forget” choice.
- Full 4K transcoding in a very small footprint
- Incredibly energy efficient and cool-running
- Much cheaper than the 4-bay alternatives
- No M.2 slots for caching or storage
- Two-bay limit means higher cost-per-TB for redundancy

Frequently Asked Questions
Do I need a Plex Pass to use hardware transcoding on these NAS units?
Yes, this is a common point of confusion. While the hardware (like the Intel J4125) is capable of transcoding, Plex requires a “Plex Pass” subscription to unlock the software hooks that use that hardware. Without it, the NAS will try to use the CPU for “Software Transcoding,” which will likely cause 4K movies to buffer and fail. If you don’t want to pay for Plex Pass, consider using Jellyfin, which offers hardware transcoding for free.
Should I buy the Synology DS923+ or the DS423+ for a media server?
For strictly media streaming, buy the DS423+. Even though the DS923+ is a more “powerful” machine with a faster Ryzen CPU and 10GbE options, it lacks an integrated GPU. This means it cannot do hardware-accelerated transcoding. If you ever need to watch a movie on a device that doesn’t support the original file format, the DS423+ will handle it smoothly, while the DS923+ will struggle significantly. The DS923+ is better for office work and VMs.
Can I use standard desktop hard drives in my media NAS?
Technically yes, but it’s a mistake. Standard desktop drives (like Seagate Barracudas) are not designed to run 24/7 or handle the vibrations of multiple drives spinning next to each other. You should specifically look for “NAS-rated” drives like Western Digital Red Plus or Seagate IronWolf. These drives have firmware optimized for RAID and can handle the constant read/write cycles of a Plex server much better over a 5-year period.
Is it possible to stream 4K movies to my phone when I’m away from home?
Yes, but this is where upload speed and transcoding come into play. A 4K movie might require 50-80Mbps of bandwidth. Most home internet connections don’t have that much upload speed. This is why you need a NAS that can transcode. The NAS will shrink that 4K file down to a 720p or 1080p stream (around 4-8Mbps) on the fly, allowing you to watch your movies smoothly over a cellular connection or hotel Wi-Fi.
When is the best time of year to buy a NAS and hard drives?
NAS enclosures rarely see massive price drops, but they often go on sale during Amazon Prime Day (July) and Black Friday. However, the best deals are usually on the hard drives themselves. I recommend watching sites like CamelCamelCamel for “shuckable” Western Digital external drives or sales on IronWolf Pro drives, which can often be found for under $15 per terabyte during holiday sales, significantly lowering your total startup cost.
Final Verdict
If you want a server that “just works” and can handle sharing your library with friends, the Synology DS423+ is the clear choice. If you are a hardware enthusiast who wants the fastest possible transfer speeds and doesn’t mind a slightly less polished interface, the Asustor AS5402T is the better value. For those with massive 100TB+ libraries and a need for professional-grade data protection, the QNAP TVS-h674 is the undisputed king. As home media files continue to grow in size with 8K on the horizon, investing in a hardware-transcoding-capable NAS today will save you from a forced upgrade tomorrow.
