Best NAS for Plex & Jellyfin 2026: Which Ones Actually Hardware-Transcode

By LK Wood IV · Published 2026-07-19 · Updated 2026-09-28 · ~13 min read · St. Louis County, MO

Start here: do you even need to transcode?

A media server does the least work when it Direct Plays, handing the file to your player untouched. From there the server’s effort climbs: Direct Play → Remux (swap the container) → Direct Stream (convert audio only) → Transcode (rebuild the video), per Jellyfin’s transcoding docs. Transcoding is the expensive step.

It is also a fallback, used when the client can’t play the file as-is or the connection can’t carry it.

Three things trigger it. The client can’t play the video codec. An unsupported container or audio track only forces a remux or direct stream, per Jellyfin’s codec support page. A bandwidth cap applies.

Plex’s CPU guide says remote access will very often require transcoding because the network often can’t carry the full quality. Or subtitles have to be burned into the picture, which Jellyfin calls the most intensive method of transcoding.

Jellyfin’s codec table marks 8-bit HEVC as fully supported in six of its eleven client columns (Safari and the Android TV app among them) and on Roku only for 4K devices, so a house of those clients rarely transcodes. If that’s you, an ARM NAS is a perfectly good storage box.

So the buying rule is to match your player to your files first, then buy exactly as much transcode headroom as the unavoidable cases demand. The case that forces your hand is 4K HDR tone-mapping, meaning 4K HDR content played on an SDR target. Jellyfin’s own hardware-selection guide is blunt about it.

Tone-mapping 4K60 Dolby Vision to 4K60 H.264 SDR “requires a Ryzen 9 5950X for faster than real-time” in software, so “a GPU is ALWAYS recommended.” That one workload is why the CPU inside your NAS, and the transcoder built into it, is the spec that matters.

The one rule: Intel Quick Sync (and what it rules out in 2026)

Quick Sync handles video decoding and encoding on Intel’s integrated GPU.

• Intel N100-class or newer (Quick Sync) → yes. N100, N150, N95, Pentium Gold 8505, Core i3-N305, Core i5-1235U and newer Intel parts with integrated graphics.
• Older Intel J- and N-series Celerons → the silicon has Quick Sync, but Jellyfin says not to buy one now. The J4125, N5105 and J6412 all carry Quick Sync hardware. Jellyfin’s hardware-selection page (last changed June 23, 2026; I read it September 26, 2026) recommends “Intel Core i5-11400, Intel Pentium Gold G7400, Intel N100, Apple M series or newer (excluding Intel J/M/N/Y series up to 11th gen)” for a server running on integrated graphics, and says of those low-power J/M/N/Y parts: “It is advised to avoid using these parts in a Jellyfin Server.” It also warns that “Intel 10th gen and older integrated graphics are losing support for QSV on Linux”, and Jellyfin’s Intel page (last changed August 31, 2026) says Ice Lake, Jasper Lake, Elkhart Lake “and older generations are losing support for QSV on Linux” and “may stop working in a few years”. Neither page says support has ended. Jellyfin tells owners of 7th-to-10th-gen chips to keep using them and tells buyers to consider a newer CPU. So do I.
• ARM / Realtek → no. No Quick Sync at all. Plex’s CPU guide expects an ARM NAS to manage “at least one stream with no transcoding”, and Jellyfin’s hardware guide lists prebuilt NAS appliances with “Realtek ARM CPUs” as potentially problematic hardware. Fine for storage and Direct Play only.
• AMD without an iGPU → no. Some embedded Ryzen parts (see Synology below) have no integrated graphics, so every transcode falls back to the CPU.
• AMD with a Radeon iGPU → it depends. Parts like the Ryzen Embedded R2514 (Radeon graphics) can hardware-transcode through VA-API. Jellyfin runs it, but its hardware guide says AMD is not recommended for integrated graphics (encoder quality and driver support), and Plex’s hardware-streaming page supports dedicated AMD cards “as is” and names no AMD integrated graphics. Buy Intel for this job.

The 2026 Synology transcode trap

In 2026 a Synology is usually the wrong buy for a Plex or Jellyfin box. Its transcoding broke in two different ways at once.

Prong one: the AMD models have no iGPU. Synology’s 25-series AMD units have no integrated graphics. The DS925+ and DS1525+ use the Ryzen V1500B, and the DS725+ uses the R1600, as the older DS723+ and DS923+ do.

Wikipedia’s Ryzen processor list gives the V1500B no GPU, and cpu-monkey’s R1600 spec sheet lists “no iGPU”.

Every transcode on these boxes runs on the CPU, and by Plex’s rule the V1500B manages two 1080p H.264 transcodes and not one 4K stream (the table below has the arithmetic).

Prong two: the Intel models had their driver removed. The 2025 DS225+ and DS425+ still ship the same Intel Celeron J4125 with Quick Sync silicon as older units, but Synology removed the iGPU kernel driver from DSM on the 25-series, disabling hardware H.264/HEVC transcoding at the software level.

Synology’s own statement, quoted in a Channels community PSA, is that “starting with products released in 2025 and beyond, even if the CPU supports hardware transcoding, we will no longer provide the driver required to enable it,” citing HEVC licensing.

The lone 2025 exception is the BeeStation Plus, for which Synology paid the codec licenses. And a J4125 with its driver is still the class of chip Jellyfin’s hardware-selection page tells buyers to avoid.

The result is a genuine consumer trap. The DS225+’s Amazon listing title still read “Intel CPU for Hardware Transcoding” on September 26, 2026, which is true about the silicon and false about what DSM will let Plex or Jellyfin do. So do not buy a current Synology Plus as an out-of-box media transcoder.

Newegg had the DS225+ at $364.99, the DS425+ at $599.99 and the DS925+ at $850.99, sold by Newegg, on September 26, 2026. Newegg’s DS925+ listing says J4125. Synology’s CPU table lists the V1500B. They are fine NAS units for many jobs.

Both retailers list them: DS225+ at Amazon or Newegg, DS425+ at Amazon or Newegg, DS925+ at Amazon or Newegg.

Hardware media transcoding is not one of those jobs in 2026. (The older Intel DS224+ and DS423+ still transcode via Quick Sync on DSM, but Synology’s CPU table lists the same Celeron J4125 in both, which puts them on Jellyfin’s avoid list too. Don’t build a 2026 purchase around finding one new.)

Streams by CPU: what each box here can transcode

Jellyfin and Plex publish no hardware stream count for these chips. Neither do UGREEN or TerraMaster.

UGREEN’s DXP4800 Plus FAQ says transcoding demand “varies substantially” with the source file, the client and the settings, and TerraMaster’s F4-424 Pro specification lists codecs up to 4K at 60 fps and stops there.

What is published is which jobs each chip does in hardware and what Jellyfin says about it. Plex adds a PassMark rule for software transcoding. The last column is the fallback. It is what you get with hardware transcoding off: Plex without a Plex Pass, a 25-series Synology, a chip with no graphics.

Plex’s rule comes from its CPU guide (last modified June 18, 2019): one full transcode needs about 2,000 PassMark from a 10 Mbps 1080p H.264 file, and 12,000 from 40 Mbps 4K SDR HEVC or 17,000 from 50 Mbps 4K HDR 10-bit HEVC transcoded to 10 Mbps 1080p, and simultaneous streams multiply it.

Plex calls it a rough guide, not a measurement. It describes Plex’s software transcoder. The PassMark figures are cpubenchmark.net averages read September 26, 2026.

The hardware cells come from Jellyfin’s Intel and AMD pages and Plex’s tone-mapping table.

The EU counts come from Wikipedia’s Alder Lake and Goldmont Plus tables. The GPU transcoding guide’s support list covers discrete cards and the other Intel generations.

Read it by the job you need done:

• Every client direct-plays at home: any row, ARM included. Buy for bays and noise.
• One or two remote 1080p streams, or Plex without a Plex Pass: an N95 or N100 box. Even in software, Plex’s rule gives it two 1080p H.264 transcodes. The F4-425 at $343.99 on September 26, 2026 is the cheapest box here that does it.
• 4K HEVC or HDR files on screens that can’t play them: hardware only. No chip in the table reaches Plex’s 12,000 for one 4K SDR transcode in software. Buy an Intel row with a yes, and with Plex, a Plex Pass.
• AV1 files: the 12th-gen Intel rows decode AV1 in hardware; Jellyfin’s floor is Gen 12 Tiger Lake, and the J4125 falls short of it. Jellyfin’s guide also says not to worry about AV1 when choosing parts, because software AV1 decoding is efficient and AV1 media isn’t common yet.
• Several 4K transcodes at once: Jellyfin’s Intel page credits the UHD 770 and Iris Xe with a second MFX video engine for concurrent transcoding, and names no NAS chip beside them; the GPU guide’s setups by use case cover the desktop chips that carry them.

Picks by use case

Every pick below is a current Intel Quick Sync box that hardware-transcodes on its shipping firmware. I have not benchmarked these boxes myself. Jellyfin’s hardware guide lists prebuilt NAS appliances as potentially problematic, for slow chips and for software environments that can make third-party apps harder to install.

If Jellyfin is the main job, weigh the mini-PC route at the end of this list.

Best budget, 2-bay: UGREEN NASync DXP2800

An Intel N100 (quad-core Alder Lake-N with UHD Quick Sync), 8GB DDR5, 2.5GbE and two M.2 slots make this my 2-bay pick with working hardware transcoding. Jellyfin recommends the N100 by name.

It decodes HEVC 10-bit and AV1 and tone-maps 4K HDR in hardware, and by Plex’s rule the chip alone manages two 1080p transcodes if hardware transcoding is off. Newegg sold it for $389.99 on September 26, 2026, shipped and sold by Newegg. The 4-bay F4-425 below cost less at $343.99 from TERRAMASTER OFFICIAL on Newegg that day.

This is the box I would buy instead of the Synology DS225+.

Best mainstream, 4-bay: UGREEN NASync DXP4800 Plus

The DXP4800 Plus pairs an Intel Pentium Gold 8505 (five-core Alder Lake with UHD Quick Sync) with 8GB DDR5, a 128GB system SSD and 10GbE plus 2.5GbE. Four bays give you room to grow. Its 48-EU graphics do the same hardware jobs as the N100’s.

And at 9,008 on PassMark it manages four 1080p software transcodes by Plex’s rule to the N100’s two. Newegg had it at $656.99 on September 26, 2026, sold by Newegg.

One caution. UGREEN sells a near-identically-named DXP4800 GT that uses an AMD Ryzen R2514 (Radeon graphics), and on September 26, 2026 it was the cheaper of the two at Newegg ($559.99). It transcodes through VAAPI on Jellyfin, which does not recommend AMD graphics.

Plex names only dedicated AMD cards, “as is”, and its tone-mapping table lists only Intel and NVIDIA. If Plex is your app, pin the “Plus” SKU, not the GT.

Most CPU headroom: TerraMaster F4-424 Pro

Step up to the Intel Core i3-N305 when the box runs more than a media server: eight cores and a 32-EU UHD iGPU, paired here with 32GB of DDR5 and dual 2.5GbE. Its 9,350 PassMark is the highest of any box on this page, four 1080p transcodes in software by Plex’s rule against the N100’s two.

TerraMaster’s spec page lists hardware transcoding for H.264/H.265/MPEG-4/VC-1 up to 4K at 60 fps. Neither Jellyfin, Plex nor TerraMaster puts a hardware stream count on the N305, or on the N100. I would not buy it for 4K transcodes alone.

On September 26, 2026 it was $859.99 at Newegg, sold through Newegg by TerraMaster’s own store (TERRAMASTER OFFICIAL).

If you want Quick Sync for less and can live with a plainer chassis, the TerraMaster F4-425 is a strong value 4-bay. Newegg’s listing names its quad-core chip as an Intel Celeron N95, with 4K H.265 hardware decode, and TerraMaster’s store sold it there for $343.99 on September 26, 2026.

The N95 is an Alder Lake-N chip from the N100’s family, newer than the Celerons Jellyfin warns about.

Already have storage: add a mini-PC

Keep media on your existing NAS. Run Plex or Jellyfin on an Intel N100 or N150 mini-PC and connect to the NAS over the network. A DAS connects directly to the mini-PC. It’s more moving parts and a little more setup. In exchange it decouples transcode compute from your disks and sidesteps the NAS software environment Jellyfin warns about.

Our best mini-PCs for a homelab guide covers the boxes with dated prices; pair one with the drives from our best NAS hard drives guide.

Plex vs Jellyfin: the transcode cost gap got wider in 2026

Pick the same Intel Quick Sync box and both apps can use it: Jellyfin and Plex both transcode through Intel Quick Sync and NVIDIA NVENC, per their own hardware pages (I go deeper in Jellyfin vs Plex). What differs is the bill.

Plex gates hardware transcoding behind a paid Plex Pass, and that price moved sharply this year: on July 1, 2026 the lifetime Plex Pass rose to $749.99 from $249.99, per Plex’s own pricing announcement; monthly and annual prices stayed put, and a 5-year plan arrived.

Plex’s plans page listed all four on September 26, 2026: $6.99 a month, $69.99 a year, $249.99 for five years and $749.99 lifetime.

Jellyfin does the same hardware transcoding for free: it is free software under the GNU GPL (jellyfin.org), and its hardware-acceleration docs list the same Quick Sync and NVENC paths.

If you’re buying a Quick Sync NAS specifically to transcode, that turns “free hardware acceleration” into a real line item against Plex’s lifetime price. Weigh it before you commit to an ecosystem.

The bottom line

Buying a NAS for Plex or Jellyfin in 2026 is not the Synology default it used to be.

Work it in order. Decide whether you even transcode, and match your player to your files first. If you do transcode, buy Intel Quick Sync on an N100-class chip or newer, which today means a UGREEN or TerraMaster Intel box or an N100/N150 mini-PC paired with storage you already own. Skip the J4125 boxes, Synology’s included.

The silicon works, but Jellyfin tells buyers to avoid that class of chip.

Then pair the box with disks from our NAS hard-drives guide, and if you’re still choosing apps, weigh Jellyfin’s free hardware transcoding against Plex’s $749.99 lifetime (Plex’s plans page, September 26, 2026) in Jellyfin vs Plex. Every price here is Newegg’s or Plex’s on September 26, 2026. Check the listing before you buy.
