The best NAS for Plex in 2026 is the UGREEN NASync DXP4800 Plus for most people, because its Intel processor includes Quick Sync hardware transcoding, it has a 10GbE port, and it costs less than comparable Synology hardware. Pick the UGREEN DXP2800 if you want the cheapest NAS that still transcodes, the TerraMaster F4-424 Pro if you want the strongest media-focused CPU, and a Synology DS925+ only if your devices direct play and you value DSM software over transcoding.
The deciding factor for a Plex NAS is not storage speed. It is whether the processor has integrated graphics that Plex can use to convert video on the fly. This guide explains why that matters, compares seven real models, shows how to calculate how many simultaneous streams you can support, and lists the settings that keep a Plex server smooth for years.

Hardware transcoding in Plex requires a paid Plex Pass subscription on the server owner’s account. Specifications are from manufacturer pages and published reviews; retailer listings sometimes disagree, so verify details for the exact SKU.
Direct play, transcoding, and why the CPU decides everything
When a device can play a file exactly as stored, Plex sends it untouched. This is direct play, and it needs almost no processing power. When the device cannot handle the file, Plex converts it on the fly. That conversion, called transcoding, is the heavy part. Common triggers are an incompatible video codec, burned-in subtitles, audio the client cannot decode, a 4K file played on a 1080p screen, or a remote stream limited to a low bitrate over the internet.
Software transcoding on a modest NAS processor struggles with a single 4K stream. Hardware transcoding hands the job to the integrated graphics chip, which can handle several simultaneous streams using a fraction of the power. Intel processors with Quick Sync are the standard answer. Several 2025 Synology Plus models have no hardware transcoding path: the Ryzen-based DS925+ has no integrated graphics, and the Intel-based DS225+ and DS425+ are reported not to ship with the graphics driver Plex needs. That is why many Plex guides now steer buyers to UGREEN, QNAP, or TerraMaster for transcoding duty.
Best overall: UGREEN NASync DXP4800 Plus
The DXP4800 Plus uses an Intel Pentium Gold 8505 with one performance core, four efficiency cores, and six threads, plus Quick Sync graphics. It has 8 GB of DDR5 memory expandable to 64 GB, four SATA bays, two M.2 PCIe 4.0 slots, one 10GbE port, one 2.5GbE port, and HDMI 2.0b. Reviewers report Plex hardware transcoding working smoothly, and it undercuts the Synology DS925+ on price while offering a faster CPU, more memory, and 10GbE.
Four bays with 12 TB drives give about 36 TB usable with single parity, plenty for a large 4K library. Use one M.2 slot for the Plex application data so library browsing stays fast.
Trade-offs: UGOS is still maturing, the warranty is two years, and the 10GbE port only helps if your computer also has 10GbE.
Best budget transcoding NAS: UGREEN NASync DXP2800
The DXP2800 has an Intel N100 with four cores, 8 GB of DDR5 memory (expandable to 16 GB), two SATA bays, two M.2 slots, and a single 2.5GbE port. The N100’s Quick Sync engine transcodes several 1080p streams and a few 4K streams at once, which covers most households. UGREEN lists a maximum capacity of 80 TB, though some retailers list less.
Two bays mean RAID 1 mirroring or two independent drives, so you get less capacity per dollar than a four-bay unit and no room to expand.
Trade-offs: only two bays and no PCIe slot or 10GbE. It is a good first Plex server and a poor choice for a library you expect to double.
Best media-class CPU: TerraMaster F4-424 Pro
The F4-424 Pro carries an Intel Core i3-N305 with eight cores, a turbo up to 3.8 GHz, and integrated UHD graphics, paired with 32 GB of DDR5 memory that cannot be upgraded. It has four SATA bays, two M.2 slots, two 2.5GbE ports, an HDMI port, and a USB-C 3.2 Gen 2 port. Reviewers call it one of the most powerful media-class four-bay NAS units available, and the large memory pool leaves room for Docker containers alongside Plex.
Trade-offs: no 10GbE and no PCIe slot, and TerraMaster’s TOS software and support network are less established than Synology’s or QNAP’s.
Best for upgraders: QNAP TS-464
The TS-464 has an Intel Celeron N5105 or N5095 (QNAP lists both), 8 GB of DDR4 memory expandable to 16 GB, four SATA bays, two M.2 slots, two 2.5GbE ports, a PCIe Gen3 x2 slot, and HDMI output. Intel Quick Sync handles Plex hardware transcoding, and the PCIe slot gives you a later path to 10GbE. HDMI output also lets some owners use the NAS as a direct media player.
Trade-offs: an older Celeron is noticeably slower than the N100 or Pentium Gold for software tasks, and QNAP’s interface has a learning curve.
Best for large libraries: UGREEN NASync DXP8800 Plus
If your library already fills several large drives or a household includes many simultaneous viewers, the DXP8800 Plus offers eight SATA bays, an Intel Core i5-1235U with Iris Xe graphics, 8 GB of DDR5 (up to 64 GB), two 10GbE ports, two Thunderbolt 4 ports, a PCIe x4 slot, and two M.2 slots. Its Iris Xe integrated graphics and ten-core CPU give the most transcoding headroom in this guide.
Trade-offs: price, power draw, and noise. It is excessive for a typical household.
Best for DSM fans who direct play: Synology DS925+
The DS925+ has an AMD Ryzen V1500B with four cores and eight threads, 4 GB of ECC memory (up to 32 GB), four SATA bays, two M.2 slots, and two 2.5GbE ports. It excels at storage, backup, and software polish, but Ryzen V1500B has no integrated graphics, so Plex cannot hardware transcode on it. Software transcoding of a 1080p stream is possible; heavy 4K conversion is not realistic.
This works if your players direct play: an Apple TV 4K, Nvidia Shield, recent smart TV, or a computer that handles your codecs. If you stream away from home at reduced bitrates, add a separate small PC for Plex or choose a different NAS.
Best for fast storage and direct play: Asustor Lockerstor 4 Gen3
The AS6804T combines an AMD Ryzen V3C14, 16 GB of ECC DDR5 memory, four SATA bays, four M.2 PCIe 4.0 slots, two 10GbE ports, two 5GbE ports, and USB4. It is built for storage speed, not transcoding, because the Ryzen lacks integrated graphics. Choose it if your Plex server also hosts editing projects or backups, and all your clients direct play.
Decision matrix
| Situation | Pick | Reason |
|---|---|---|
| Remote streaming or mixed devices | UGREEN DXP4800 Plus | Hardware transcoding plus 10GbE |
| First server, small library | UGREEN DXP2800 | Lowest cost with Quick Sync |
| Many Docker apps plus Plex | TerraMaster F4-424 Pro | 32 GB memory, strong CPU |
| Want PCIe expansion later | QNAP TS-464 | PCIe slot for 10GbE card |
| Large household, many streams | UGREEN DXP8800 Plus | Most transcoding headroom |
| All clients direct play, want DSM | Synology DS925+ | Best software, no transcoding needed |
| Fast pool, editing projects | Asustor AS6804T | NVMe slots and dual 10GbE |
How many streams can you support? A worked calculation
Network bandwidth
A 4K remux streams at roughly 80 megabits per second. A gigabit network carries around 900 megabits in practice, so about eleven such streams, which is far more than a household needs. Your internet upload speed is the real limit for remote viewers: a 20 megabit upload supports two streams at 8 megabits each.
Transcoding capacity
Quick Sync capacity depends on the generation of the chip, but a rough planning rule is that an N100-class processor can transcode several 1080p streams or a small number of 4K HDR streams, and tone-mapping HDR to SDR consumes extra resources. Plan for the worst case: if three people may watch remotely at once, each needing a transcode, choose a processor above the N100 class.
Storage example
A library of 300 films at 40 GB averages 12 TB. Add 5 TB of television and 30 percent growth, about 22 TB. Single-parity protection across four 8 TB drives gives 24 TB usable, a close fit, so four 12 TB drives (36 TB usable) leave comfortable headroom.
Plex settings that make a NAS smooth
- Enable hardware acceleration in Plex Media Server settings (requires Plex Pass) and confirm transcode sessions show an acceleration label.
- Move the Plex application data folder to NVMe storage to speed up library browsing and thumbnails.
- Set the transcoder temporary directory to an SSD or RAM disk so transcoding does not hammer the hard drives.
- Prefer direct play: use clients that support your codecs, and convert unusual files once with a batch encode.
- Limit remote streaming quality to a bitrate your upload can sustain.
- Schedule library scans and thumbnail generation for overnight hours.
Pair the NAS with CMR NAS drives, and keep a backup of the Plex database and your irreplaceable files. RAID does not replace a backup.
Troubleshooting buffering and stutter
When playback stalls, identify which resource is the bottleneck before buying hardware. Open the Plex dashboard during a problem stream. If it says the stream is transcoding and the label does not show hardware acceleration, the CPU is doing the work in software, which is the usual cause of stutter on low-power processors. If it says direct play and the video still stutters, suspect the network: weak Wi-Fi on the client, a congested powerline adapter, or a slow link between the router and the NAS.
If the stream is a hardware transcode but still stutters, look at temperatures and storage. A drive that has spun down needs several seconds to wake, and a nearly full volume with heavy background scans can slow reads. Move the transcode folder to an SSD, reschedule maintenance tasks, and check the NAS resource monitor for sustained high CPU or disk wait times.
For remote viewers, verify that the server has a direct connection rather than a relayed one. A relay caps bandwidth at a low bitrate and forces transcoding. Forward the Plex port on the router, or use a secure alternative, and confirm in the settings that remote access shows as fully accessible.
Jellyfin and Emby as alternatives
Everything above applies equally to Jellyfin and Emby. Jellyfin is free and open source, and it supports hardware transcoding without a subscription on Intel graphics, which makes the UGREEN, TerraMaster, and QNAP picks even more attractive. The trade-off is a less polished client ecosystem and fewer built-in remote features. Emby sits between the two, with a paid tier that unlocks hardware transcoding. Whichever server you choose, the processor still determines how many conversions you can run at once, so the same buying logic holds.
Organizing a library so everything matches correctly
Plex matches titles using folder and file names, and a consistent structure prevents wrong posters and missing episodes. Keep separate top-level folders for films and television. Name films with the title and year, such as Title (2020), one folder per film. For television, use a show folder with season subfolders and episode names that include the season and episode number. Keep extras such as trailers and behind-the-scenes clips in a clearly named subfolder so they do not appear as separate films.
Store original files and avoid renaming them after the library is built. Back up the Plex database regularly; it contains watch history, ratings, and custom metadata that take a long time to recreate. A weekly copy to another volume costs almost nothing in space.
Drive layout for a Plex NAS
A tidy layout uses three tiers. The first is the main storage pool: CMR hard drives holding the media, set up with single or double parity depending on how irreplaceable the content is. The second is an NVMe volume holding the Plex application data and a transcode folder, which keeps browsing fast and spares the hard drives from constant small writes. The third is a backup target, either an external drive or a second NAS, holding the database and any personal videos. Following this layout means a failed hard drive does not interrupt browsing, and a rebuilt array does not take the application data with it.
Capacity planning should include the transcode folder. A 4K transcode can create a temporary file of several gigabytes per active stream, so give the SSD room for at least a few concurrent sessions, and clear the folder if a crashed session leaves files behind.
Remote access without exposing your NAS
Streaming outside the home is where a Plex NAS earns its keep, and it is also where careless setup creates risk. Forward only the Plex port, never the NAS management interface. Keep the NAS and Plex updated, use a long unique administrator password with two-factor authentication, and create a separate Plex account for each family member instead of sharing one login. If you would rather not open any ports, a private VPN into your home network lets your own devices reach the server securely, although guests will still need standard Plex sharing.
Finally, set an upload bandwidth limit for remote streams that leaves room for your household. A 20 megabit connection shared by two remote viewers at 8 megabits each leaves almost nothing for video calls at home, so cap remote quality and let Plex transcode down for those streams.
Frequently Asked Questions
Do I need a Plex Pass for a NAS?
Plex runs without it, but hardware transcoding is a Plex Pass feature. If you stream away from home or to devices that need conversion, the subscription is what makes a transcoding-capable NAS worthwhile.
Can a Synology NAS run Plex well?
Yes, for direct play. Several 2025 Synology Plus models cannot hardware transcode, so they struggle if clients need conversion. Check whether your devices direct play before choosing one.
How much RAM does a Plex NAS need?
Plex itself is light, and 4 to 8 GB is enough for most libraries. More memory helps if the NAS also runs Docker containers or virtual machines.
Is 2.5GbE enough for Plex?
Yes. Even a 4K remux needs about 80 megabits per second, so a gigabit network handles many streams. Faster ports mainly help with backups and large file transfers.
Should I install Plex on the NAS or a separate PC?
Run it on the NAS if the NAS has hardware transcoding, because it keeps everything in one low-power box. If you chose a model without it, a small Intel mini PC reading media over the network is a good alternative.
Which hard drives are best for a Plex NAS?
CMR NAS drives such as WD Red Plus or Seagate IronWolf in the 8 to 12 TB range suit most libraries. Choose quiet drives if the server is in a living area.
