Best NAS for Plex in 2026: 5 Current Picks

Almost any NAS can store a Plex library. The product decision changes when a client cannot direct play and the server must decode, tone-map, subtitle-render, or re-encode video.

This guide avoids fixed “simultaneous stream” promises. A 1080p H.264 transcode without subtitles is not equivalent to 4K HEVC HDR tone mapping with image-based subtitles. Validate the actual library and client mix.

Quick verdict

The QNAP TS-464 is the best all-around Plex NAS because it combines Intel integrated graphics, four bays, dual 2.5GbE, M.2 slots, and PCIe expansion.

Choose the TerraMaster for heavier co-located applications, the ASUSTOR for compact NVMe flexibility, the DS225+ for a small DSM-managed library, or the DS925+ for direct play and separate compute.

Plan for direct play first

Direct play sends the existing media file to the client. It requires network bandwidth but little server compute. Transcoding changes the file because the client cannot accept the codec, container, bitrate, resolution, HDR format, audio format, or subtitles.

Before buying a larger server:

1. Inventory the source codecs and HDR formats.
2. Identify every client device.
3. Check whether subtitles trigger video burn-in.
4. Measure remote bandwidth.
5. Test representative files.

Better clients often eliminate more transcoding than a faster NAS.

QNAP TS-464

The TS-464 is the balanced appliance. Intel integrated graphics provides a supported hardware path for compatible Plex workloads, while four bays and PCIe expansion leave room for library and network growth.

Verify that the Plex process or container has access to the graphics device. Hardware capability does nothing when the container mapping or application setting is wrong.

TerraMaster F4-424 Pro

The Core i3-N305 and 32GB of installed memory make the F4-424 Pro appropriate when Plex shares the NAS with indexing, photo management, download automation, and other containers.

Its tradeoff is a less mature appliance ecosystem. Document configuration and recovery rather than relying on the hardware specification alone.

ASUSTOR AS5402T

The AS5402T pairs an Intel N5105 with two SATA bays and four M.2 slots. It fits a compact design where large media lives on HDDs and application data or active media lives on NVMe.

Synology DS225+

The DS225+ is the current compact Synology option. It combines an Intel J4125 with 2.5GbE, 1GbE, and DSM. Two bays and a 6GB memory maximum define the growth ceiling.

The prior DS224+ should not be presented as the current model.

Synology DS925+

The DS925+ uses an AMD V1500B without an integrated GPU. It remains a good Plex storage target when clients direct play.

For a larger library, a clean architecture is often:

• DS925+ for resilient storage and backup.
• A mini PC or GPU server for Plex compute.
• NFS or SMB between them over 2.5GbE.

That split keeps media application upgrades away from the storage appliance.

Bottom line

Buy the QNAP TS-464 for the most balanced single-box Plex NAS. Buy the TerraMaster when the application stack is heavier, the ASUSTOR for NVMe-heavy compact storage, or the DS225+ for DSM in two bays.

Buy the DS925+ for Plex only when direct play dominates or separate compute handles transcoding.
