Head-to-head
ASUSTOR AS5404T vs QNAP TS-464: Four onboard NVMe drives or a supported PCIe upgrade
The short answer
Choose AS5404T when four built-in NVMe slots are central to your storage layout. Choose TS-464 when a supported PCIe upgrade is more important than those extra SSD sockets. Both have four SATA bays and two 2.5GbE ports. Check RAM, drives and network adapters as one complete configuration.
Before you choose
The reasoning and the trade-offs
Two mirrored SSD pairs need four physical slots
AS5404T has enough onboard sockets for two two-drive NVMe pairs. TS-464 has two onboard sockets total.
What this is based on
Two mirrored pairs require four drives. This counts sockets and does not prescribe filesystem or pool configuration.
Main trade-off
QNAP TS-464-8G-US
There are only two onboard NVMe slots.

What matters in practice
The differences that matter
Two mirrored SSD pairs need four physical slots
AS5404T has enough onboard sockets for two two-drive NVMe pairs. TS-464 has two onboard sockets total.
How we reached this conclusion
Two mirrored pairs require four drives. This counts sockets and does not prescribe filesystem or pool configuration.
A future 10GbE client favors the expansion slot
TS-464 supports an optional 10GbE PCIe card, while AS5404T has no comparable general-purpose slot in its specification.
How we reached this conclusion
Both start with two 2.5GbE sockets. The supported adapter route is the differentiator.
The RAM upgrade belongs in the initial basket
The selected TS-464 starts with 8 GB while AS5404T starts with 4 GB.
How we reached this conclusion
This is installed memory capacity, without a claim about application speed.

Meaningful differences
What changes the fit
| What changes | ASUSTOR Nimbustor 4 Gen2 | QNAP TS-464-8G-US | Why it matters |
|---|---|---|---|
| SATA bays | 4 | 4 | Both hold the same number of internal SATA drives. |
| M.2 NVMe slots | 4 | 2 | Two mirrored NVMe pairs require four sockets. |
| Built-in Ethernet | Two 2.5GbE ports | Two 2.5GbE ports | Four SSDs do not change the built-in network link speed. |
| PCIe expansion card slot | No general-purpose PCIe card slot listed | One Gen3 x2 slot | TS-464 provides an official route to a compatible 10GbE card. |
| Selected base RAM | 4 GB | 8 GB | Application plans can add a memory upgrade to the ASUSTOR basket. |
What you give up
Every choice has a cost
If you choose ASUSTOR Nimbustor 4 Gen2
- No general-purpose PCIe card slot is listed.
If you choose QNAP TS-464-8G-US
- A 10GbE card is a separate compatible purchase.
Recommendation switch
The decision flips if...
My layout needs four onboard NVMe drives
Choose ASUSTOR Nimbustor 4 Gen2. AS5404T provides the required socket count.
My upgrade plan includes a supported 10GbE PCIe card
Choose QNAP TS-464-8G-US. TS-464 has an expansion slot.
I expect either package to include native 10GbE
Choose neither. Both built-in interfaces are 2.5GbE.
What matters in practice
How to make the call
Two mirrored SSD pairs need four physical slots
If you want separate mirrored SSD storage for active work and applications, AS5404T supplies four onboard positions. TS-464 needs another supported storage route for the same four-drive plan. Confirm ADM or QTS pool rules before purchasing the drives. Four positions do not establish greater throughput for an individual application.
A future 10GbE client favors the expansion slot
Choose TS-464 if the intended next step is a 10GbE workstation and a supported add-in card. Include the adapter and client network hardware in the budget. AS5404T can be attractive for local SSD organization, but its four M.2 sockets should not be mistaken for four faster network paths.
The RAM upgrade belongs in the initial basket
When the planned applications already need more than 4 GB, price and verify a supported ASUSTOR memory upgrade before comparing the two baskets. For file storage with modest app needs, the original memory may be enough. Extra RAM does not remove a network bottleneck or create additional drive bays.
What this comparison cannot tell you
- No matched app, Plex, storage or noise tests were performed.
