NAS for Plex & Jellyfin: transcoding

A source-backed guide to choosing a NAS or box for Plex and Jellyfin — why the 2025 Ryzen Synology models can't hardware-transcode, and the Intel options that can.

Who this is for

Choosing a box for Plex or Jellyfin comes down to one question: will your apps transcode, or direct-play? It matters more than ever in 2026 because Synology's new Ryzen Plus models dropped hardware transcoding entirely. This guide frames the decision around that, with every claim sourced. For the operational side of transcoding, see the Plex/Jellyfin transcoding hardware runbook; to compare the NAS platforms themselves, see Synology vs UGREEN vs DIY.

Bottom line

Start with direct play — if your clients (Apple TV, modern smart TVs, Shield, current phones) play your files as-is, the box never transcodes and almost anything works. If you *do* need to transcode, you need Intel Quick Sync (or a GPU): the 2025 Ryzen Synology models (DS925+/DS1825+) have no integrated GPU and can't hardware-transcode — buy them only for direct-play libraries. A UGREEN NASync (Intel) keeps Quick Sync in a turnkey NAS; a DIY Intel N100/N305 mini-PC gives the most transcode-per-dollar. Remember Plex needs a Plex Pass for hardware transcoding; Jellyfin's is free.

How to choose

Will your clients direct-play?
Direct Play sends the file untouched when the client supports it — near-zero server work, no quality loss, and the preferred outcome. If your apps direct-play your library, transcoding hardware barely matters and a Ryzen Synology is fine.
Plex Pass vs Jellyfin
Plex requires an active Plex Pass to use hardware-accelerated transcoding; without it, Plex falls back to CPU software encoding. Jellyfin's hardware acceleration is free. Factor the Plex Pass into the cost if you'll lean on Plex transcoding.
Quick Sync (or a GPU) for transcoding
Hardware transcoding needs Intel Quick Sync (the common path) or a discrete/integrated GPU. The 2025 AMD Ryzen Synology models have no iGPU at all; UGREEN's Intel NASync and Intel N-series mini-PCs do have Quick Sync.
Turnkey appliance vs DIY
A UGREEN NASync gives you transcoding in a finished, warrantied box (younger software). A DIY Intel mini-PC gives the most transcode-per-watt and per-dollar, but you own the OS and updates — a common split is an AMD Synology for files plus an N100 mini-PC for Plex.

The options

AV1 hardware decode works on all the Intel options here (Alder-Lake media engine); AV1 hardware encode does not (it needs Arc or Meteor Lake and newer).

Synology 2025 Plus (DS925+ / DS1825+)

Synology

Synology's 2025 desktop Plus models use the AMD Ryzen V1500B — an embedded CPU with no integrated GPU and therefore no hardware video transcoding. An excellent file/backup/app NAS that is a poor on-the-fly transcoder.

Best for

Buyers whose Plex/Jellyfin clients can direct-play their library, and who value DSM's mature backup, snapshot, and app ecosystem and ECC memory over media muscle.

Watch-outs

If any client needs to transcode (e.g. 4K HEVC down to a weak TV app or remote stream), this is the wrong box — transcodes fall back to slow CPU software encoding. A clear break from older Intel Synology models that had Quick Sync.

Hardware transcode capabilityNo hardware video transcode — Plex/Jellyfin must use CPU software encoding, which struggles with 4K/HEVC. (Synology also removed the i915 driver in DSM 7.2.2, disabling HW transcode on its older Intel models too.)Researchedsource
Best media useDirect play only: store H.264/HEVC files your clients natively support so the NAS never has to transcode.Researchedsource

UGREEN NASync (Intel)

UGREEN

UGREEN's NASync line uses Intel CPUs with integrated UHD graphics and Quick Sync, so it can hardware-transcode in Plex (with Plex Pass) and Jellyfin (free) — the turnkey-NAS answer for transcoding that the 2025 AMD Synology line no longer offers.

Best for

Buyers who want a finished, warrantied NAS appliance and real hardware transcoding for mixed or older clients — e.g. transcoding 4K HEVC down to 1080p for a weak TV app or a remote stream.

Watch-outs

UGOS is younger and less mature than DSM. Confirm the specific SKU's CPU — the 2-bay DXP2800 uses the N100, the DXP4800 Plus the Pentium 8505, higher models Core i5 variants — since the transcode ceiling differs.

DIY Intel N100 / N305 mini-PC

DIY / Intel

A low-power Intel Alder-Lake-N mini-PC (N100, or the 8-core N305) is the enthusiast's transcode workhorse: a ~6–15 W box whose Quick Sync engine can hardware-transcode multiple 4K streams. Run Plex/Jellyfin bare-metal or in Docker, alongside a separate storage NAS.

Best for

Hands-on operators who want the best transcode value and don't mind self-managing the OS and containers — including the popular split where an AMD Synology holds files and the mini-PC does all transcoding.

Watch-outs

No appliance warranty on the software stack — you own setup and updates. Plex still needs a Plex Pass; mini-PCs lack ECC and built-in multi-bay redundancy, so pair with real storage and backups.

Pick by use case

Every client direct-plays your library, and you want the best file/backup NAS

Synology 2025 Plus (DS925+ / DS1825+). If nothing has to transcode, the Ryzen Synology's lack of Quick Sync is irrelevant and you get DSM's mature ecosystem and ECC.

You need real hardware transcoding in a finished, warrantied NAS appliance

UGREEN NASync (Intel). Its Intel Quick Sync handles 4K-to-1080p transcodes out of the box for mixed/older clients — the turnkey Intel option the 2025 Synology line dropped.

You want maximum transcode-per-dollar and will self-manage the stack

DIY Intel N100 / N305 mini-PC. A ~6–15 W Quick Sync box transcodes multiple streams cheaply; pair it with a NAS for storage.

You already own a 2025 Ryzen Synology but now need to transcode

DIY Intel N100 / N305 mini-PC. Add a cheap N100 mini-PC to run Plex/Jellyfin with Quick Sync and keep the Synology purely for files — the standard files-plus-mini-PC split.
