Main trade-off
ASUSTOR Nimbustor 2 Gen2
Only two SATA drives fit internally.
Head-to-head
ASUSTOR AS5402T vs QNAP TS-464: Six drive positions each, but the SATA and NVMe mix differs
The short answer
Choose AS5402T for two SATA drives plus as many as four onboard NVMe drives. Choose TS-464 for up to four SATA drives plus two NVMe drives, or a supported PCIe expansion card. Both have six internal drive positions in total, but those positions accept different drive types and cannot be exchanged.
Before you choose
The reasoning and the trade-offs
Six drive positions can hide an incompatible drive plan
AS5402T allocates its six positions as two SATA and four NVMe. TS-464 allocates them as four SATA and two NVMe.
What this is based on
2 plus 4 equals 6 on both sides, but the connector counts are not interchangeable.
Main trade-off
QNAP TS-464-8G-US
Only two onboard M.2 sockets are provided.

About this comparison
Compare AS5402T and TS-464 for the split between SATA and NVMe storage, a PCIe network upgrade and installed RAM.
Choose AS5402T for two SATA drives plus as many as four onboard NVMe drives. Choose TS-464 for up to four SATA drives plus two NVMe drives, or a supported PCIe expansion card. Both have six internal drive positions in total, but those positions accept different drive types and cannot be exchanged.
Winner by situation

What matters in practice
The differences that matter
Six drive positions can hide an incompatible drive plan
AS5402T allocates its six positions as two SATA and four NVMe. TS-464 allocates them as four SATA and two NVMe.
How we reached this conclusion
2 plus 4 equals 6 on both sides, but the connector counts are not interchangeable.
The faster-network route depends on the expansion slot
TS-464 documents a compatible PCIe card path to 10GbE. AS5402T has no comparable general-purpose slot.
How we reached this conclusion
Both start with dual 2.5GbE ports, so the optional adapter is a separate purchase.
The smaller chassis starts with half the memory
AS5402T ships with 4 GB and the selected TS-464-8G-US ships with 8 GB.
How we reached this conclusion
8 GB divided by 4 GB equals two. This is capacity arithmetic, not an application-speed result.

QNAP TS-464-8G-US
The chassis has 4-bay storage. Its fastest documented network path is 2.5 Gbps.
- Best matched use
- Install four SATA drives
Checked facts
- SATA drive positions: 4
- M.2 NVMe positions: 2
- Built-in Ethernet: Two 2.5GbE ports
- General-purpose PCIe slot: One Gen3 x2 slot
Meaningful differences
What changes the fit
| What changes | ASUSTOR Nimbustor 2 Gen2 | QNAP TS-464-8G-US | Why it matters |
|---|---|---|---|
| SATA drive positions | 2 | 4 | Extra M.2 positions cannot accept your spare SATA hard drives. |
| M.2 NVMe positions | 4 | 2 | Extra SATA bays do not become onboard NVMe sockets. |
| Built-in Ethernet | Two 2.5GbE ports | Two 2.5GbE ports | Their original port-speed class is the same. |
| General-purpose PCIe slot | None listed | One Gen3 x2 slot | QNAP provides the documented optional 10GbE card route. |
| Selected installed memory | 4 GB | 8 GB | An 8 GB starting requirement changes the ASUSTOR basket. |
What you give up
Every choice has a cost
If you choose ASUSTOR Nimbustor 2 Gen2
- An 8 GB starting plan adds a compatible memory purchase.
If you choose QNAP TS-464-8G-US
- The optional network card uses the single PCIe slot.
Recommendation switch
The decision flips if...
My drive plan includes four onboard NVMe SSDs
Choose ASUSTOR Nimbustor 2 Gen2. AS5402T supplies four sockets.
I need four SATA HDDs or a PCIe card
Choose QNAP TS-464-8G-US. TS-464 supplies those hardware paths.
I need four SATA HDDs and four onboard NVMe SSDs
Choose neither. Neither selected layout provides both counts.
What matters in practice
How to make the call
Six drive positions can hide an incompatible drive plan
List the physical drives you intend to reuse. Four SATA HDDs select TS-464 immediately. Two HDDs with four onboard NVMe SSDs select AS5402T instead. A six-position headline can conceal the wrong connector mix. This counts physical hardware only and does not promise that every desired RAID layout or migration is supported.
The faster-network route depends on the expansion slot
Choose TS-464 if a supported 10GbE card is already in the upgrade plan. Include the card, client adapter and any needed switch in the budget. AS5402T can provide more onboard SSD sockets, but that does not increase the speed of each built-in Ethernet port. Do not count its two ports as an automatic five-gigabit single-client link.
The smaller chassis starts with half the memory
If the planned workload already calls for 8 GB, price a supported ASUSTOR memory upgrade alongside the drives. TS-464 meets that installed-capacity requirement in the selected package. For modest file sharing, that capacity difference may not decide the outcome. Confirm the actual app requirements instead of assuming twice the RAM means twice the useful performance.
What this comparison cannot tell you
- No performance, reliability or acoustic comparison was measured. An empty bay or slot does not guarantee an in-place migration path.
