About this comparison
QNAP TS-464-8G-US and Synology DS425+ compared by drive layout, network and processor, best use.
The practical choice turns on best use, then on the constraints in your own setup.
Before you choose
How they fit your plans
Two future upgrades may compete for the same QNAP slot
If the plan includes a network upgrade and another PCIe accessory, TS-464’s single expansion slot makes the exact card choice important. Two separate cards cannot occupy it together. Investigate a supported combination card or decide which job takes priority before buying. Choose QNAP for a verified expansion plan, or DS425+ when its built-in connections are sufficient and the added hardware would go unused.
Facts behind this advice
TS-464 has one PCIe Gen3 x2 slot. QNAP offers different expansion roles, but compatibility, card size and shared bandwidth must be checked for the chosen model. DS425+ does not list a comparable general expansion slot.
A Synology photo-library purchase can need an immediate RAM upgrade
DS425+ ships with 2GB memory. If object recognition in Synology Photos is part of the family archive, include a compatible upgrade that clears the documented 4GB minimum. QNAP’s selected 8GB configuration avoids that particular small-memory starting point, but uses different photo software. Choose the photo workflow first, then budget its exact requirements rather than comparing RAM as a proxy for recognition quality.
Facts behind this advice
Synology explicitly publishes the object-recognition minimum. The selected TS-464-8G has 8GB. Neither fact establishes relative recognition accuracy, indexing time or support for identical albums and search features.
Winner by situation
Start with what you need it to do
Run Plex at home
Both records list “2.5 Gbps network. Plex use supported” for network and processor. Both records show the same result for “Network and processor”, so this row does not separate them.

Meaningful differences
What changes the fit
| What changes | QNAP TS-464-8G-US | Synology DiskStation DS425+ | Why it matters |
|---|---|---|---|
| Drive layout | 4 storage bays | 4 storage bays | Both records show the same result for “Drive layout”, so this row does not separate them. |
| Network and processor | 2.5 Gbps network. Plex use supported | 2.5 Gbps network. Plex use supported | Both records show the same result for “Network and processor”, so this row does not separate them. |
What you give up
Every choice has a cost
If you choose QNAP TS-464-8G-US
- 10GbE needs a separate PCIe adapter.
If you choose Synology DiskStation DS425+
- There is no 10GbE upgrade path.
What matters in practice
How to make the call
The useful difference
Both have four SATA bays, two M.2 slots and Intel Celeron J4125 or N5095 class processors.
What the numbers change
TS-464 has HDMI and PCIe expansion.
The trade-off
DS425+ starts with 2GB while this TS-464 variation has 8GB.
What this comparison cannot tell you
- Drive compatibility changes over time.
- Real transfer speed depends on the full network and drive array.
- Plex behavior depends on the exact media format and client.
