The best NAS for Plex in 2026 depends on where Plex Media Server runs and how often your clients need transcoding. For an all-in-one four-bay server with a documented Intel graphics path, the QNAP TS-464 is the clearest pick in this shortlist. The Synology DS925+ is the stronger storage-first choice for a large library and mostly direct-play clients, while the two-bay Synology DS224+ suits smaller collections. None should be assigned a guaranteed 4K stream count from specifications alone: playback depends on the exact Plex compatibility entry, codecs, subtitles, clients, Plex Pass, software versions and concurrent workload.
Use this guide to choose between Plex on the NAS and Plex on a separate computer, size your storage, verify transcoding support and secure the server before exposing it to the internet.

Which NAS should you buy for Plex in 2026?
Choose the QNAP TS-464 if Plex Media Server must run on the NAS and you want four bays plus a documented Intel graphics engine to investigate for hardware-accelerated transcoding. QNAP lists an Intel Celeron N5095, Intel UHD Graphics, four drive bays and 2.5GbE networking in its TS-464 hardware specification. That makes it the most straightforward all-in-one candidate here, not a promise of a particular number of simultaneous 4K conversions.
Choose the Synology DS925+ when capacity, expansion and a storage-focused design matter more than running every conversion on the NAS. Synology lists four bays, an AMD Ryzen processor, 2.5GbE and expansion options in the DS925+ specifications. Its listed processor is not an Intel Quick Sync part, so buyers who expect frequent transcoding should plan separate compute or verify the exact Plex compatibility information for their workload.

Choose the Synology DS224+ for a smaller collection and a compact two-bay enclosure. Its product specifications list an Intel Celeron J4125 with integrated graphics. Two bays limit usable capacity and future expansion, and Plex compatibility still needs to be checked for the current server package and the media you intend to play.
Should Plex Media Server run on the NAS or another computer?
The first buying decision is the server location, not the brand. A NAS can store every movie and episode while Plex Media Server runs on a desktop, mini PC or other computer mounted to the NAS; Plex explicitly describes this as a valid approach when the NAS is not the right compute platform.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesRunning Plex on the NAS keeps the installation compact and can reduce the number of devices that must stay powered. It also concentrates storage, database, metadata, network service and transcoding demands in one box. If a client requests a conversion, the NAS processor or graphics engine must handle it while the system continues serving files and managing other applications.
Separate compute costs more and adds setup work, but it decouples storage from transcoding. You can select a NAS for bays, redundancy and expansion, then upgrade the computer that runs Plex without replacing the disk enclosure. Plex’s guidance on whether Plex Media Server on a NAS is right for you and its NAS limitations article are useful checks before committing.
Why is the QNAP TS-464 the all-in-one pick?
The TS-464 combines four bays with an Intel Celeron N5095 and Intel UHD Graphics. That profile gives a buyer a clear hardware path to investigate when Plex needs conversions, while four bays provide more flexibility than a two-bay enclosure for capacity planning and redundancy.
Hardware on the specification sheet is only one part of the decision. Plex says model compatibility, supported codecs, operating-system support and the server workload determine whether hardware-accelerated streaming works. The Plex NAS Compatibility List should be checked for the exact TS-464 entry and current package status, rather than assuming that every N5095-based configuration behaves identically.

Intel’s Quick Sync reference describes the underlying media technology, but it is not a Plex benchmark for this NAS.
The TS-464 is therefore the best fit for a buyer who wants one four-bay box, understands that direct play is preferable, and is prepared to verify Plex Pass, model support, codecs and subtitles before relying on transcoding. Do not buy it on the assumption that the N5095 specification guarantees a fixed count of 4K streams.

When is the Synology DS925+ the better choice?
The DS925+ is the storage-first four-bay option. Its four bays let you build a larger usable pool than a two-bay unit, and Synology lists 2.5GbE networking and expansion options for future growth. It is especially sensible when your televisions, streaming boxes and mobile clients can direct play most of the library.
Direct play means the client can read the file’s container, video and audio codecs, resolution and subtitle format without conversion. In that situation, the NAS mainly reads data and sends it over the network; the demanding video conversion stage is avoided. Network speed still matters for high-bitrate files and remote access, but faster Ethernet cannot replace compute when a client requires transcoding.
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →Synology identifies an AMD Ryzen processor for the DS925+, not an Intel Quick Sync processor. That does not make Plex impossible: you can use direct play, verify the model’s current Plex compatibility entry, or run Plex on a separate computer with the DS925+ mounted as storage. It does mean the DS925+ should not be presented as an Intel hardware-transcoding solution.
Pick the DS925+ when your priority is a four-bay library, expansion and a clean separation between storage and compute. If your household frequently watches incompatible 4K files, uses image-based subtitles or serves many remote clients, budget for separate Plex compute rather than assuming the NAS processor will cover every case.
Is the Synology DS224+ enough for a small Plex library?
The DS224+ is the compact two-bay NAS for Plex in this shortlist. Synology lists an Intel Celeron J4125 with integrated graphics, giving it a documented graphics capability to investigate for compatible hardware acceleration while keeping the enclosure smaller than the four-bay choices.
Two bays are the decisive trade-off. They limit the number of disks you can use, the maximum practical library size and your options for expanding later. A two-disk redundant arrangement can protect against a single drive failure, but redundancy is not a backup; important media, personal recordings and metadata still need a separate backup strategy.

Before purchasing, check the current Plex compatibility list for the DS224+ and the server package available in your region. The J4125 specification does not establish a guaranteed stream count, and subtitles, unusual codecs, remote clients and simultaneous viewers can change the workload substantially.
How do direct play and transcoding affect NAS choice?
Direct play is the easiest workload for a NAS because the original file is sent to a compatible client without conversion. Transcoding is required when the client cannot decode the source video or audio, when the bitrate must be reduced for a connection, or when subtitle handling forces a video conversion. Plex Media Server then uses CPU or supported graphics hardware, and concurrent conversions compete for the same resources.

Make a list of every playback device: smart televisions, streaming boxes, game consoles, phones, tablets and web browsers. Record the formats in your library, including common video codecs, audio codecs, containers, 4K or high-dynamic-range files and the subtitle types you use. A library that is direct-play friendly on a home television may still transcode for a browser or a remote phone.
Plex’s Media Server requirements and compatibility documentation explain why there is no universal “X streams” answer. The exact model, Plex version, codec, resolution, subtitle behavior, client and number of viewers all matter. Treat vendor specifications as capability clues, not comparative Plex measurements.
What does hardware-accelerated streaming require?
Hardware acceleration moves supported decode or encode work from general-purpose CPU cores to an integrated graphics engine or other compatible media hardware. It can reduce CPU load, but it is not automatic and does not support every codec, subtitle path or conversion scenario.
- Confirm that the exact NAS model appears in Plex’s current compatibility information.
- Confirm that Plex Media Server is available for the NAS operating system and that the package channel is current.
- Use a Plex Pass account; Plex states that hardware-accelerated streaming requires Plex Pass.
- Check that the source and target codecs, resolution and subtitle behavior are compatible with the hardware path.
- Allow for CPU work even when acceleration is enabled, because unsupported stages can still fall back to software processing.
The TS-464’s Intel UHD Graphics and the DS224+’s integrated graphics are reasons to investigate this path. The DS925+’s AMD Ryzen specification should instead push a storage-first buyer toward direct play or separate Plex compute unless current model-specific documentation confirms the required behavior.
How many 4K Plex streams can these NAS models handle?
The supplied official specifications do not establish a reliable stream count for any of these models, so a responsible buying guide cannot promise a number of simultaneous 4K streams. A stream may direct play, require a light audio conversion, trigger a full video transcode, or become much heavier when subtitles are burned into the picture.
Remote viewers add another variable because the server may need to reduce bitrate for each connection. The same NAS can appear idle with compatible local clients and become compute-bound when several remote users request different resolutions. Use your actual clients and media formats as the sizing input, and avoid transferring a third-party benchmark to an official product claim.
How many drive bays and how much expansion do you need?
Bay count determines how easily you can grow the library, replace disks and balance usable capacity against redundancy. The DS224+ has two bays; the TS-464 and DS925+ each have four. A four-bay enclosure generally gives a growing collection more room to add capacity without immediately replacing every existing disk, while a two-bay unit favors a smaller, simpler setup.
Calculate usable capacity from the size of your media, expected annual growth, a safety margin and the redundancy layout supported by your storage system. Keep a separate backup: RAID or a similar redundant arrangement helps with a failed disk but does not protect against accidental deletion, corruption, theft or ransomware.

Drive support and expansion details can vary by model, firmware and region. Check the vendor’s current compatibility list for the exact disks you plan to buy, and verify expansion-unit support before treating an advertised expansion option as part of your final capacity plan.
Does 2.5GbE matter for Plex?
Both the TS-464 and DS925+ list 2.5GbE, which can help with multiple high-bitrate transfers, large file copies and a busy household when the rest of the network also supports that speed. The DS224+ specifications should be checked for the networking configuration relevant to your purchase.
Recommended Free Tools
2.5GbE does not solve a transcoding bottleneck. If a client needs video conversion, the server’s codec support and compute resources are the limiting factors; a faster link cannot make an unsupported hardware path work. For remote Plex access, upload bandwidth, router configuration and the viewer’s connection are equally important.
How should you set up a NAS for Plex?
Gather the NAS, compatible disks, a separate backup target, a wired network connection where possible, a Plex account and a clear list of playback clients. Decide whether Plex runs on the NAS or on another computer before creating libraries, because that choice determines where the server database, metadata and transcoding workload live.
- Plan the storage layout. Estimate current media, growth, redundancy and backup capacity. Check the exact NAS drive-compatibility list and do not count redundant space as available media capacity.
- Install and update the NAS operating system. Apply the vendor’s current firmware and security updates before exposing services to the internet.
- Choose the Plex server location. Install Plex Media Server on the NAS only after confirming the model and package channel, or install it on a separate computer and mount the NAS media folders there.
- Check Plex compatibility. Review the current NAS compatibility list, including the exact model, operating-system version and package availability.
- Organize libraries. Use separate, clearly named folders for movies, television, music and personal recordings. Keep the Plex database and metadata on reliable storage and include them in your backup plan.
- Map clients to workloads. Identify which devices direct play and which request conversion. Pay special attention to web browsers, remote phones and subtitle-heavy content.
- Enable hardware acceleration only when eligible. Confirm Plex Pass, model support, compatible codecs and current software before enabling the option. Do not treat the checkbox as proof that every conversion will use the graphics engine.
- Test configuration without making performance promises. Play representative files on each client, inspect Plex’s playback information for Direct Play or Transcode, and correct client quality or subtitle settings when appropriate.
- Secure remote access. Use strong account credentials, current firmware and a current Plex Media Server build. Restrict unnecessary exposed services and review remote-access settings after updates.
What Plex security update should buyers know about?
Plex announced that Media Server versions earlier than 1.43.3.10861 were affected by actively exploited vulnerabilities and recommended updating. The official announcement states: “We recommend all server owners and Desktop users update to the latest version as soon as possible.” Plex also warned that a NAS package may lag behind the newest release.
Before exposing a new NAS installation to the internet, check the installed Plex Media Server version and the NAS manufacturer’s package channel. Plex’s security announcement does not state that every vendor, model and region had delivered the fixed package at the same time, so verify the actual version on your system. Plex’s security announcement includes current remediation guidance and should take precedence over an old package listing.
If an internet-reachable server is below the fixed version Plex identifies, follow the announcement’s remediation instructions and assume the server may have been compromised. Updating the NAS operating system alone is not enough if the Plex package remains old.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What are the main buying pitfalls?
- Choosing by CPU name alone: A processor specification does not prove Plex compatibility, hardware acceleration or a stream count.
- Ignoring subtitles: Some subtitle workflows can force video conversion even when the underlying file would otherwise direct play.
- Confusing redundancy with backup: A mirrored or parity array cannot restore deleted or encrypted files by itself.
- Assuming all clients behave alike: A television app, browser, console and phone may request different formats from the same library.
- Buying too few bays: A two-bay NAS can become a capacity problem when the library grows or when you need a safer replacement process.
- Relying on faster networking to fix transcoding: Ethernet speed affects data transfer, not unsupported codec conversion.
- Exposing an outdated server: Check the Plex version and package channel before enabling remote access.
- Forgetting total cost: Include disks, backup storage, Plex Pass where needed, separate compute if applicable, power and setup time.
Which setup fits your Plex workload?
| Your situation | Most suitable direction | Why |

Frequently asked questions
Can Plex run without a Plex Pass on a NAS?
Plex Media Server can be installed and used for ordinary library serving without hardware-accelerated streaming, but Plex states that hardware-accelerated streaming requires Plex Pass. If your plan depends on the NAS graphics engine for conversions, include Plex Pass in the requirements and verify the account is active.
Is a NAS hard drive backup enough for a Plex library?
No. A second copy on a separate device or location is needed to recover from deletion, corruption, ransomware, theft or a failed enclosure. RAID-style redundancy improves availability after a disk failure but is not a substitute for an independently managed backup.
Why does Plex transcode a file that my television appears to support?
The television may support the video codec but not the audio track, container, bitrate, subtitle format or selected quality level. Check Plex’s playback information to identify the exact conversion trigger, then try a compatible audio track, subtitle setting or client quality option before replacing hardware.
Should remote Plex users buy the fastest Ethernet NAS?
Not necessarily. Remote playback is constrained by the server’s upload connection, the viewer’s download connection and whether the client can direct play. Faster NAS Ethernet helps local transfers, but remote transcoding still depends on compatible codecs, Plex Pass where required and sufficient compute.
How often should I recheck NAS and Plex compatibility?
Recheck when you change the NAS operating system, Plex package, client applications, media codecs or remote-access setup. Product availability, package rollout, regional listings and Plex compatibility entries can change, so confirm the current vendor and Plex pages immediately before purchase and after major updates.

Frequently Asked Questions
Can Plex run without a Plex Pass on a NAS?
Plex Media Server can serve a library without hardware-accelerated streaming, but Plex says hardware-accelerated streaming requires Plex Pass. If your NAS purchase depends on graphics-assisted transcoding, include Plex Pass and verify the account before enabling that feature.
Is a NAS hard drive backup enough for a Plex library?
No. RAID-style redundancy helps with a failed disk but cannot restore deleted, corrupted or encrypted files. Keep an independent backup on separate storage or at another location.
Why does Plex transcode a file that my television appears to support?
The client may support the video codec but not the audio track, container, bitrate, subtitle format or selected quality level. Inspect Plex playback information and try a compatible track or subtitle setting before upgrading hardware.
Should remote Plex users buy the fastest Ethernet NAS?
Not necessarily. Remote playback depends on upload bandwidth and client compatibility; faster local Ethernet does not remove the compute needed for transcoding. Prioritize direct-play compatibility and adequate Plex compute.
