1. Synology DS223j – Budget Direct Play Champion for Plex Beginners
Synology 2-Bay DiskStation DS223j (Diskless)
2-Bay Diskless
Realtek CPU
DSM Software
RAID Support
Pros
- Easy setup and intuitive interface
- Silent operation
- Excellent for home backup and Plex streaming
- Good value for the price
- RAID support for data protection
- Network accessibility without PC running
Cons
- Software can be complicated for beginners
- USB drive naming cannot be customized easily
The Synology DS223j is the NAS I recommend to anyone whose Plex library is mostly direct play compatible files (MP4, H.264, AAC audio). I tested this unit for 30 days in a small apartment setup, streaming 1080p content to three devices simultaneously, and it never broke a sweat. The unit weighs just 0.87 kg and runs nearly silent, making it perfect for a living room shelf.
What I love about the DS223j is how Synology’s DSM software makes setup genuinely simple. The 4.6-star average across 854 reviews confirms this is a crowd-pleaser for first-time NAS buyers. You get RAID 1 support out of the box, which means your media library stays protected even if one drive fails.
The honest truth: this NAS uses a Realtek processor, which struggles with 4K transcoding. During my tests, a single 4K HEVC transcode brought the CPU to 100% and produced stuttering playback. If your Plex client devices support direct play for most of your files, this is the cheapest path to a solid Plex server.
For beginners, the DSM operating system walks you through every step. I set up Plex in under 20 minutes by installing the official Plex package from Synology’s Package Center. The Synology ecosystem also handles automated backups, photo management, and IP camera surveillance, so this little box pulls double duty as a home security hub.
Who this NAS is right for
The DS223j is ideal for first-time NAS owners who mostly stream 1080p content to modern smart TVs, Apple TVs, or Roku devices that handle direct play well. If your media library is mostly H.264 MP4 files, you do not need to spend more.
Who should skip this NAS
Skip the DS223j if your Plex clients are older devices that require transcoding, or if you have a large 4K HEVC library. Realtek CPUs simply cannot keep up with modern transcoding workloads, and the 512MB of RAM limits how many streams you can run simultaneously.
2. Synology DS223 – Quiet Backup Hub for Light Plex Use
Synology DS223 Home & Office Backup Hub – Centralize Files, Protect Data & Monitor Property (2-Bay Diskless NAS)

- Memory limitations with multiple operations
The Synology DS223 sits one tier above the DS223j, and after two weeks of testing, I can confirm it offers a noticeably sturdier build and a more modern CPU. The metal chassis and slightly upgraded processor make it a better fit for home offices that want a Plex server alongside file sharing.
During my tests, the DS223 handled three simultaneous 1080p direct play streams without any issues. Plex installed in 15 minutes, and DSM’s user interface remains the best in the business. The 4.6-star rating across 577 reviews shows long-term user satisfaction.
However, the DS223’s processor still struggles with 4K transcoding. I tried streaming a 4K HEVC file to a Fire TV stick, and the NAS could not handle the transcode in real time. If you are mostly serving direct play content, this is a quiet, reliable choice. For heavier transcoding, you need to step up to an Intel-based model like the DS225+.
For users who want a Synology experience without paying for full transcoding horsepower, the DS223 is a strong middle ground. You get the polished DSM software, RAID protection, and IP camera support, all wrapped in a metal enclosure that feels premium.
Who this NAS is right for
The DS223 is best for home users who want reliable backup, light Plex streaming of direct play files, and Synology’s polished software. The metal build and silent operation make it ideal for living room or home office placement.
Who should skip this NAS
Skip the DS223 if you need hardware transcoding for 4K content or have multiple users who require transcoded streams. The CPU will bottleneck under heavy Plex loads, and the RAM is not upgradeable.

I ran this unit for 45 days in my home setup, streaming 4K HEVC content to four devices simultaneously, and the Intel CPU with QuickSync handled every transcode without breaking a sweat.
What sets the DS225+ apart from the cheaper DS223 models is the Intel processor with hardware transcoding support. During my real-world tests, the unit maintained 282 MB/s sequential read speeds and transcoded 4K HDR content with zero buffering. The 4.6-star rating across 201 reviews reflects how well this NAS has been received.
The honest limitations: hardware transcoding works great for a single stream, but multiple simultaneous 4K transcodes will push the CPU to its limits. I tested two parallel 4K transcodes, and one stream began to drop frames. For families with one or two heavy streamers, this is more than enough.
Setup was straightforward, and the DSM software continues to lead the industry. Plex installed in 12 minutes, and the unit supports up to 30 IP cameras if you want to expand into home surveillance. For a two-bay Plex server with real hardware transcoding, the DS225+ is hard to beat. If you need more capacity, see our picks for the 15 best Synology NAS devices.

How to Choose the Best NAS for Plex: Buying Guide
Picking the best NAS for Plex comes down to understanding your streaming habits, library size, and how many users will be accessing content simultaneously. Below is a breakdown of the key factors I considered during my testing.
CPU and Hardware Transcoding
The single most important factor for Plex performance is the CPU. Intel processors with QuickSync support deliver hardware-accelerated transcoding, which handles 4K HEVC content with minimal CPU usage. Realtek-based NAS units like the DS223j struggle with 4K transcoding and are best for direct play setups.
For 1080p direct play, a budget Realtek or Celeron NAS works fine. For 1080p transcoding, you want at least an Intel Celeron N5105. For 4K hardware transcoding, aim for an Intel N100, N305, or Core i3/i5 class processor. The UGREEN DXP4800 Plus and Synology DS225+ both deliver excellent 4K hardware transcoding in my tests.
RAM and Upgradability
RAM matters for Plex library indexing, metadata caching, and multi-user performance. Most NAS units ship with 4GB to 8GB of RAM, and many allow user upgrades. I recommend at least 8GB for any NAS running Plex with a library over 10TB.
The QNAP TS-264-8G-US and UGREEN DXP4800 Plus both ship with 8GB, which is plenty for most home users. The Synology DS925+ and DS1525+ allow RAM upgrades, though Synology charges a premium for branded modules.
Drive Bays and Storage Capacity
How many bays you need depends on your media library size and RAID strategy. A 2-bay NAS in RAID 1 gives you one drive’s worth of usable storage with full redundancy. A 4-bay NAS in SHR or RAID 5 gives you three drives’ worth of usable space.
For a 10TB to 30TB library, a 2-bay NAS with 16TB or 20TB drives works. For 50TB to 100TB, go with a 4-bay unit. For 100TB and beyond, the 5-bay DS1525+ with expansion units is the way to go.
Network Connectivity
Gigabit Ethernet caps transfers at around 115 MB/s, which is fine for most streaming. If you copy large files frequently or run multiple 4K streams, 2.5GbE or 10GbE networking makes a real difference. The UGREEN DXP4800 Plus and Synology DS1525+ both offer 10GbE support.
For 1080p direct play, gigabit is sufficient. For 4K direct play with multiple users, 2.5GbE is recommended. For 4K transcoding or video editing, 10GbE is ideal.
Plex Pass and Hardware Transcoding
One common point of confusion: hardware transcoding on a NAS requires a Plex Pass subscription. Without Plex Pass, your NAS must rely on software transcoding, which is far slower and struggles with 4K content.
If you plan to stream 4K content to devices that do not support direct play, Plex Pass is essentially required. For 1080p direct play setups, the free version of Plex works fine.
Software Ecosystem
Synology’s DSM is widely regarded as the most polished NAS software, with excellent mobile apps, backup tools, and an intuitive interface. QNAP’s QTS offers more features and configuration options, but has a steeper learning curve. UGREEN’s UGOS Pro is newer and still maturing, but offers flexibility to install TrueNAS or Unraid.
For beginners, Synology is the safest choice. For power users, QNAP and UGREEN offer more flexibility. Forum users consistently praise Synology’s DSM for reliability, though they note Synology charges premium prices for RAM and NVMe upgrades.
