Main trade-off
Synology DiskStation DS1825+
The stock network links are 2.5GbE.
Head-to-head
Choose DS1825+ when eight internal SATA positions and DSM are the requirements. Choose DXP6800 Pro when six bays are enough and native dual 10GbE or a supported memory upgrade beyond 32 GB is more useful. The larger Synology drive count does not provide faster Ethernet or a higher RAM ceiling in the supplied package.
Before you choose
Six drives occupy all DXP6800 Pro SATA bays and leave two empty positions in DS1825+.
What this is based on
Eight minus six leaves two spare physical bays. Six minus six leaves none.
Main trade-off
The stock network links are 2.5GbE.
Main trade-off
A six-drive installation fills every SATA bay.


Compare DS1825+ and DXP6800 Pro for eight SATA positions, immediate 10GbE and a supported memory plan beyond 32 GB.

Winner by situation
DXP6800 Pro provides six bays.
UGREEN includes the faster ports.
DS1825+ publishes 32 GB maximum.
Both provide the required connector counts.
What matters in practice
Six drives occupy all DXP6800 Pro SATA bays and leave two empty positions in DS1825+.
Eight minus six leaves two spare physical bays. Six minus six leaves none.
DXP6800 Pro supplies two 10GbE sockets. DS1825+ needs a compatible add-in card for that link rate.
The native port-rate difference is 10 versus 2.5GbE. Actual transfers also depend on the drives and network path.
DXP6800 Pro supports up to 64 GB. DS1825+ publishes 32 GB, even though it has more HDD bays.
64 GB is twice the Synology supported ceiling. Both packages start with 8 GB.

Synology, DS1825+
Eight SATA bays with ECC memory and a supported PCIe route to 10GbE or 25GbE networking.

UGREEN, DXP6800 Pro
Six SATA bays with two native 10GbE ports, two NVMe sockets and a 64 GB supported memory ceiling.
Meaningful differences
| What changes | Synology DiskStation DS1825+ | UGREEN NASync DXP6800 Pro | Why it matters |
|---|---|---|---|
| Internal SATA bays | 8 | 6 | The larger count can preserve spare positions after the initial build. |
| NVMe sockets | 2 | 2 | Both have the same onboard M.2 count. |
| Native Ethernet | Two 2.5GbE ports | Two 10GbE ports | The six-bay model supplies the higher rated link without a card. |
| Supported network-card path | Compatible 10GbE or 25GbE PCIe card | PCIe x4 slot, dual 10GbE already built in | A physical slot still requires verified card and software compatibility. |
| Supplied and maximum RAM | 8 GB ECC, up to 32 GB | 8 GB DDR5, up to 64 GB | The platform with more drive bays has the lower supported RAM ceiling. |
| Stock operating system | DSM | UGOS Pro | The app and storage-pool plan must work on the selected platform. |
What you give up
Recommendation switch
Choose Synology DiskStation DS1825+. DS1825+ fits that storage and software plan.
Choose UGREEN NASync DXP6800 Pro. DXP6800 Pro supplies the relevant published hardware.
Choose neither. Neither compared configuration combines both requirements.
What matters in practice
Choose DS1825+ when the plan reserves internal positions for two more SATA drives. If the drive count will stay at six, those extra positions may add little. Both products still provide two NVMe sockets. Before assuming the spare SATA bays support a seamless future upgrade, check the chosen operating system, RAID layout and migration procedure.
For a workstation that already has a suitable 10GbE adapter, UGREEN supplies the matching NAS interface in the original box. Include a network card when pricing the Synology configuration. DS1825+ can support a documented 25GbE upgrade, which matters for a different network plan. Neither option establishes a measured editing-stream count.
When a verified UGOS-compatible workload needs 64 GB, the six-bay model has the relevant capacity after a memory purchase. If the application requires DSM instead, the larger memory number cannot override that software requirement. Synology documents system-level ECC memory, while UGREEN lists DDR5 on-die correction. Those are separate hardware considerations rather than a matched reliability result.
