The catch
QNAP TS-264-8G-US
No single-parity layout fits in two bays.
Side by side
The TS-264 is right when QTS and a supported PCIe adapter solve your brief. For a simpler route, the DXP2800 offers N100-based UGOS Pro with one 2.5GbE port.
Before you buy
Before formatting, this example gives 12TB with QNAP TS-264-8G-US and 12TB with UGREEN NASync DXP2800. Moving to another chassis does not add protected capacity.
Where this comes from
Suppose each SATA bay holds a supported 12TB disk. A two-bay RAID 1 gives the usable capacity of one disk. With three or more drives, RAID 5 usable TB = (drive count minus 1) × 12. The layout is only an illustration. It is not storage that comes included, and it is not a backup.
The catch
No single-parity layout fits in two bays.
The catch
Only two SATA bays means limited growth and no parity layouts.

Which of TS-264-8G-US and DXP2800 fits depends on protected storage, included networking and the exact SSD or application layout you need.
Expansion and software set these two compact Intel NAS models apart.
Which one fits
Here two disks use RAID 1 and three or more use RAID 5. QNAP TS-264-8G-US gives 12TB and UGREEN NASync DXP2800 gives 12TB before formatting. A different chassis does not raise this protected capacity.
The ports included run at 2.5GbE and 2.5GbE. Read the 100GB calculation together with the real client speed.
QNAP TS-264-8G-US has 8 GB RAM and supports 16 GB, and UGREEN NASync DXP2800 has 8 GB and supports 16 GB. Compare the stated application memory requirement with the supplied configuration first, and only then budget for an upgrade. RAM capacity alone does not establish application speed.
Two physical 2.5GbE ports on the TS-264 let a direct workstation segment and a LAN connection each take their own interface. With a single 2.5GbE port, the DXP2800 needs some other supported networking approach to get the same physical layout.
In practice
Before formatting, this example gives 12TB with QNAP TS-264-8G-US and 12TB with UGREEN NASync DXP2800. Moving to another chassis does not add protected capacity.
Suppose each SATA bay holds a supported 12TB disk. A two-bay RAID 1 gives the usable capacity of one disk. With three or more drives, RAID 5 usable TB = (drive count minus 1) × 12. The layout is only an illustration. It is not storage that comes included, and it is not a backup.
At line rate, the minimum is 320 seconds for QNAP TS-264-8G-US and 320 seconds for UGREEN NASync DXP2800. Real copies take longer. With a 1GbE client the lower bound becomes 800 seconds for both.
Decimal 100GB × 8 = 800 gigabits. Take the fastest included port rate, 2.5Gbps or 2.5Gbps, and divide 800 by it. Protocol overhead is ignored here only because this is a lower-bound calculation. Optional adapters and aggregated ports are left out.
Two physical 2.5GbE ports on the TS-264 let a direct workstation segment and a LAN connection each take their own interface. With a single 2.5GbE port, the DXP2800 needs some other supported networking approach to get the same physical layout.
The topology calls for 2 wired network interfaces. TS-264 has 2 and DXP2800 has 1. Separate interfaces do not raise the speed of any single transfer by themselves, and they need correct routing.

QNAP, TS-264-8G-US
This is a 2-bay chassis, and 2.5 Gbps is the fastest network path documented for it.

UGREEN, DXP2800
This is a 2-bay chassis, and 2.5 Gbps is the fastest network path documented for it.
Spec by spec
| Spec | QNAP TS-264-8G-US | UGREEN NASync DXP2800 | In practice |
|---|---|---|---|
| Processor | Intel Celeron N5095 | Intel N100 | The platform determines the media engines, the application architecture and the concurrency. |
| Software and expansion route | QTS with PCIe expansion slot | UGOS Pro | Pick the applications and supported add-ons the job calls for. |
| Included Ethernet port count | Two 2.5GbE ports | One 2.5GbE port | On the QNAP, a dedicated workstation cable and the household LAN can each use a separate physical interface. |
| PCIe expansion slot | PCIe Gen 3 x2 slot | No PCIe card slot documented | If the planned storage or network layout outgrows the onboard interfaces, look at a supported QNAP adapter. |
Trade-offs
Change of plan
Go with QNAP TS-264-8G-US. QTS, two 2.5 GbE interfaces and a PCIe slot come with TS-264. A direct workstation connection and a separate LAN connection can each use their own physical port.
Go with UGREEN NASync DXP2800. DXP2800 is built on an Intel N100 platform and comes with 8 GB RAM, two SATA bays and two M.2 positions. Its single 2.5 GbE interface has to handle the planned network layout.
Decision guide
The TS-264 is right when QTS and a supported PCIe adapter solve your brief. For a simpler route, the DXP2800 offers N100-based UGOS Pro with one 2.5GbE port.
Two SATA bays, two M.2 slots and 8GB supplied memory are common to both, so none of those values is a reason to upgrade from either to the other.
Dual 2.5GbE ports and a PCIe slot come on the TS-264. Extra network paths can keep traffic apart, but a single transfer gains only when the client, protocol and network configuration support the intended path.
