Key takeaways
- Cache SSDs: the DXP2800’s dual M.2 slots can hold SSDs for caching or fast volumes, which helps with metadata and thumbnails. Plex’s database benefits from fast storage.
- Metadata location: store the Plex library database on SSD where the NAS allows, and keep media on the hard drives.
- Backups: RAID is not backup. Keep copies of irreplaceable files, such as home videos, on a separate device or off-site service.
For most households running Plex, the UGREEN DXP2800 or the Synology DS224+ is the right size: both pair an Intel CPU with Quick Sync hardware transcoding in a two-bay case. Buyers with many simultaneous streams or 4K libraries should look at the UGREEN DXP4800 Plus or the QNAP TS-464, and anyone who only plays files directly to capable TVs and streaming boxes can save money with a low-power model that does not transcode. The processor matters more than almost any other spec, because it decides whether the NAS can convert video on the fly for phones, remote viewers and older TVs.
What Plex needs from a NAS
Plex either direct plays a file, when the playing device supports its format, or transcodes it, when the device cannot. Direct play barely touches the CPU. Transcoding is the heavy part, which is why reviewers keep pointing to x86 chips with Intel Quick Sync graphics. One 2026 buyer’s guide states that Intel CPUs beat AMD for this job on a NAS because of Quick Sync. Plex documents that hardware-accelerated streaming requires a paid Plex Pass subscription, so factor that into your plan; consult Plex’s support pages for current requirements.
ARM-based NAS units are generally direct-play only. The same guide flags a trap: Synology’s DS225+ looks newer than the DS224+, yet the guide says Synology removed the kernel graphics driver, disabling Plex hardware transcoding on that model, making the older DS224+ the better pick for this specific job. Another roundup also says the DS225+ is listed with a Realtek ARM chip. Because reviewers disagree on the exact chip, read the maker’s current specification sheet and Plex forum notes before buying any Synology value-line model.

CPU, RAM and networking
CPU and transcoding
The UGREEN DXP2800’s Intel N100 belongs to the Alder Lake-N family and offers Quick Sync, which reviewers value for modern codecs. The older Celeron J4125 inside the Synology DS224+ also has Quick Sync, which is why the unit remains popular despite its age. The QNAP TS-464’s Celeron chips have Quick Sync as well. Newer chips tend to handle more streams and higher bitrates, while older chips may struggle with certain modern formats such as HEVC tone mapping; consult Plex’s documentation for what your server can do.
RAM
Plex itself is modest on memory, but a NAS also runs its operating system, containers and indexing. Eight gigabytes is a comfortable level for Plex plus a few other apps. The DXP2800 ships with 8GB DDR5 as reported, and the TS-464 with 8GB DDR4.
Network ports
A single gigabit port is enough for a handful of 1080p streams, but 4K remux files, which can carry very high bitrates, push the limit. The DXP4800 Plus reportedly has a 10GbE port plus a 2.5GbE one, and the TS-464 has dual 2.5GbE. These help when several viewers stream while you copy files. The rest of your network, including switch and router, must match.
Bays, drives and capacity
Two bays are enough for a mirrored pair, which protects against one drive failure but does not replace backup. Four bays give you more total space and options such as RAID 5, with the trade-offs the NAS maker describes. Use drives the NAS maker lists as compatible, and prefer NAS-rated models, which are designed for continuous operation and vibration in multi-bay enclosures. Plan capacity from your library: movies and series add up quickly, especially at 4K.
- Cache SSDs: the DXP2800’s dual M.2 slots can hold SSDs for caching or fast volumes, which helps with metadata and thumbnails. Plex’s database benefits from fast storage.
- Metadata location: store the Plex library database on SSD where the NAS allows, and keep media on the hard drives.
- Backups: RAID is not backup. Keep copies of irreplaceable files, such as home videos, on a separate device or off-site service.
Budget tiers
Budget
Synology’s DS223j is the low-cost direct-play route in one roundup, with no transcoding. It suits households whose TVs and boxes handle their library’s formats natively. The TerraMaster F2-425 appears as a cheap x86 option for those who want transcoding without spending much, though reviewers rate its software as less refined.
Mid-range
This is where most buyers should land. The UGREEN DXP2800 draws praise for value and its dual M.2 slots. The Synology DS224+ remains the choice of buyers who want DSM, a mature app ecosystem and strong Plex community support. Both are two-bay devices with Quick Sync.
Premium
The UGREEN DXP4800 Plus is named by two roundups as a top pick for transcoding power and fast networking. The QNAP TS-464 and TS-264 give you more ports and, on the TS-464, an HDMI output that some users connect directly to a television. Premium units also tend to be bulkier and louder.
Pick X if you…
| If you… | Pick | Why |
|---|---|---|
| Want the best two-bay value | UGREEN DXP2800 | N100 with Quick Sync, 8GB DDR5, dual M.2 |
| Prefer the most polished software | Synology DS224+ | DSM maturity and Plex compatibility |
| Stream to many users or hold large 4K files | UGREEN DXP4800 Plus | Faster CPU and 10GbE |
| Want four bays and HDMI | QNAP TS-464 | Four bays, dual 2.5GbE, HDMI as reported |
| Only direct play to capable devices | Synology DS223j | Low-cost, no transcoding |
| Want to stay away from a transcoding trap | Avoid the DS225+ for Plex | Reportedly lacks hardware transcoding |
Setup and care
- Ventilation: give the NAS airflow on all sides, and keep it away from heat sources.
- Power protection: pair it with a UPS so a power cut does not interrupt a write.
- Updates: keep the NAS operating system and Plex up to date, and close unneeded remote access ports.
- Remote access: use strong passwords and two-factor sign-in on both the NAS and Plex accounts.
- Noise: multi-drive enclosures can be audible. Place the unit away from sleeping areas.
- Drive failure: if a drive fails, replace it promptly and let the array rebuild. If data becomes inaccessible, stop writing and contact a professional recovery service.
Alternatives worth considering
- A small PC or mini PC as a Plex server: offers strong transcoding at a low cost, but you manage the operating system and storage yourself.
- Nvidia Shield or similar streaming boxes with an external drive: a simple direct-play setup.
- Jellyfin or Emby on the same NAS: similar server software with different licensing; confirm the NAS maker’s app support.
Matching the NAS to your household
A single viewer with a modern television and a library of common formats can be perfectly well served by a direct-play machine, and in that case money is better spent on drives than on a faster processor. A family where phones, tablets and a few older TVs stream at once, or where relatives watch remotely over a limited internet upload connection, needs transcoding headroom, and that is where Quick Sync models such as the DXP2800, DS224+ and TS-464 earn their place. A collector who keeps untouched 4K discs at very high bitrates should prioritize network bandwidth and bays: the DXP4800 Plus and its 10GbE port are aimed at that buyer, according to roundups.
Think two or three years ahead. Libraries grow faster than expected, and swapping drives for larger ones is easy only if the enclosure has the bays and the maker supports the capacity you want. Check the maker’s compatibility list, and give the extra bay or the M.2 cache slots some thought even if you do not use them on day one.
Frequently Asked Questions
Do I need a NAS that can transcode?
Only if your devices cannot play your files natively, or if you stream remotely at lower bitrates. If every TV and box handles your formats, a direct-play NAS is enough.
Is the Synology DS225+ good for Plex?
One 2026 guide advises against it, saying the kernel graphics driver was removed so hardware transcoding is disabled. Read the maker’s current specification and Plex forum notes before choosing a Synology value-line model.
How much RAM does a Plex NAS need?
Eight gigabytes is comfortable for Plex plus a few other apps. Models like the DXP2800 and TS-464 are reported with 8GB.
Do I need 10GbE?
Not for most homes. A gigabit or 2.5GbE port serves a few streams. Ten-gigabit helps with large file transfers and many simultaneous users, if your switch and computer support it.
How many bays should I buy?
Two bays suit most libraries, with mirrored drives. Four bays give more capacity and options but cost more and take more space.
Is RAID a backup?
No. RAID protects against a single drive failure but not accidental deletion, malware or fire. Keep a separate backup of irreplaceable files.
