The catch
QNAP TS-464-8G-US
Setup takes care given the interface's many controls.
Side by side
The TS-464 brings HDMI, hardware transcoding and PCIe expansion. The DS425+ is the better match if you want the Synology DSM workflow.

How QNAP TS-464-8G-US and Synology DS425+ differ in drive layout, network, processor and best use.
This one comes down to best use first, then to the limits of your own setup.
Day to day
When the plan covers a network upgrade as well as another PCIe accessory, TS-464’s single expansion slot makes the exact card choice matter, since two separate cards cannot sit in it together. Before buying, look into a supported combination card or decide which job comes first. QNAP is the one for a verified expansion plan. DS425+ is the better fit if its built-in connections are enough and extra hardware would sit unused.
The one PCIe Gen3 x2 slot on TS-464 can serve different expansion roles in QNAP's lineup, but you must check compatibility, card size and shared bandwidth for the model you pick. DS425+ lists no comparable general expansion slot.
The DS425+ comes with 2GB of memory. When the family archive relies on object recognition in Synology Photos, add a compatible upgrade that gets past the documented 4GB minimum. The selected 8GB QNAP configuration sidesteps that low starting memory, though its photo software is different. Decide on the photo workflow first and budget for its exact requirements. Do not treat RAM as a stand-in for recognition quality.
The object-recognition minimum is published outright by Synology, and the selected TS-464-8G has 8GB. Neither fact shows how the two compare on recognition accuracy or indexing time, or whether they support identical albums and search features.
Which one fits
Both models list “2.5 Gbps network. Plex use supported” for network and processor. Both models show the same result for “Network and processor”, so this row won't decide between them.
Converting compatible 4K files for remote viewers is where a hardware video engine matters on a NAS.
The library stays protected and still usable when storage is redundant and photos can be reached remotely.
Plugging straight into a TV only works if the NAS has a display output of its own.
A compatible processor and enough usable memory are what containers and home apps depend on.
On a first NAS, guided setup and clear software count for more than deep controls.

Spec by spec
| Spec | QNAP TS-464-8G-US | Synology DiskStation DS425+ | In practice |
|---|---|---|---|
| Drive layout | 4 storage bays | 4 storage bays | Both models show the same result for “Drive layout”, so this row won't decide between them. |
| Network and processor | 2.5 Gbps network. Plex use supported | 2.5 Gbps network. Plex use supported | Both models show the same result for “Network and processor”, so this row won't decide between them. |
Trade-offs
Decision guide
Intel Celeron J4125 or N5095 class processors, four SATA bays and two M.2 slots are shared by both.
The TS-464 adds HDMI and PCIe expansion.
This TS-464 variation comes with 8GB, against a 2GB start on the DS425+.
